| Information On Cupola Casting And The Process Of Cupola Casting A Cupola is a type of furnace that is very much alike to blast furnace. The Cupola furnace is refractory lined, stack of steel that is around 20 to 35 feet high. It rests on a base plate that is made of cast iron and has four legs. The casting that is obtained from the cupola furnace is known as a cupola casting. Cupola Furnace: The Cupola furnace is one of the oldest forms of furnace that have been used by the iron and metal foundries. The Cupola furnace is the crudest and the simplest furnace that has been used by the industries. However, the cupola’s use is declining and the furnace is fast being extinct. Merits of the Cupola Furnace: Though the electric or the blast furnace has started replacing the Cupola Furnace, it has some special benefits of its own. The Cupola furnace can always remain continuously in action. The furnace also offers a very high melting rate. The most important merit of the furnace is that it has relatively very low melting cost. The furnace has also permits a lot of ease of operation. However, due to the invention and development of the electric furnace, the use of Cupola furnaces has substantially declined. The electric furnace melts a much larger amount of metal. The operation cost of the electric furnace is also very low. The electric furnace also emits a much smaller level of smoke heat and also pollutants. Construction of the Cupola furnace: The Cupola furnace is constructed in a crude and simple manner. The Cupola furnace is a vertical structure like a steel shell. The steel is lined with refractory bricks from the inside. The furnace has an opening half way in the vertical shaft. The charge is introduced through the opening. The charge is divided into different layers. It contains the metal that is to be melted. The metal is mixed with coke, fuel, and lime stone flux. The fuel is burnt directly into the air and is introduced in to the furnace through the tuyeres which are positioned above the hearth. The hot gases that have been produced ascend and pre heat the charge. The cupolas in majority of the cases have drop down doors. The bottoms can be dropped down to facilitate the cleaning and the repairs. At bottom in front of the furnace is a tap hole. The molten metal is removed from the tap hole. At the rear there is also another slag hole. The top of the stag is covered with a spark or fume arrester. Usually the cupola has a diameter of 405 to 2000 mm. It is operated on varying fuels for different metal ratios. The molten metal that can be produced in the copula of this size at a speed of 1 to 30 tones per hour. Continuity of process: After the process of melting has ended, the charging is halted. However, the blast of hot air is always maintained till all the metal has been melted and has been taken out from the tap hole. When the air cools down, the doors at the bottom are opened and the residue that has been left behind is removed. |

| Iron Casting Information And The Process Of Iron Casting Iron castings can be referred to as products made out of melted iron molecules. These molecules are, first, poured into mold and allowed to cool. They are then extracted. The casting properties depend a great deal on the foundry practice. They also depend on the cooling rate. Iron contains huge carbon concentrations. This content facilitates melting, simplicity of casting, and machining. Iron casting designs have a great variation owing to the property of iron to resist shrinkage during the process of cooling. The end product attains a great reputation for its strength and durability. Tensile strength ranges between 20,000 psi and over 60,000 psi. The values of hardness (without heat treatment) range between 100 and 300 BHN. Some factors need to be considered while buying iron castings. The first thing on the agenda should be, checking the quality of foundry used in products and procedures. This should be done because foundry practices determine the casting properties. The consumer might have a tough time in finding the apt one. Secondly, the concentration of carbon should be looked into. The percentage of carbon commonly ranges between 2.5 and 4%. An addition of even 0.1% would cause the tensile strength to decrease by around 2700 psi. Casting procedures differ from foundry to foundry. Green sand molding is the most commonly used type of casting. Normally, small and medium sized products are produced using this type of casting. Shell molding is preferred for bigger applications. Shell molding facilitates cooling of the mold containing heated metal. This process gives a better finishing to the final product as compared to all the other processes. Centrifugal casting is used for producing big cylinders and pipes. Both, producer and consumer would get highly satisfied if a proper blend of correct casting process and reputed foundry is made. Iron castings are utilized extensively in machinery, automotive, and agricultural industry. Parts such as turbine and pump housings, dynamometer bases, compressors are made out of iron castings. Majority of manufacturers have the caliber to go for high and low production outputs. They are also entitled to go for short order runs. There are standard prototypes ensuring customer satisfaction and accuracy. Some manufacturers provide finishing services like galvanizing, painting, and machining as well. In general, iron castings include alloy casting, ductile castings, and malleable castings. There are some terms relating to iron castings. They need to be known in order to get a fair idea of iron. Brinell Hardness Number (BHN): It can be defined as the method used for measuring the hardness of iron. For iron castings, a metal ball of 3000Kg is put on a flat iron piece. After the removal of ball, indentation observed is recorded. This measurement indicates the value of hardness. Tensile Strength: Tensile strength can be defined as the quantity of bending and stretching undergone by a material before tearing or breaking. Here the metal is iron. Modulus of Elasticity: It can be defined as the ratio of stress to strain. This value determines the elasticity as well as the stiffness of the concerned material. |

| Information On Casting Sand And Green Sand Or Foundry Sand Green Sand: Green sand is also called as foundry sand or molding sand. This is utilized for sand casting. When this sand is oiled or moistened, it has a tendency to pack well and retain the shape. Green sand is a mix of pulverized coal, water, bentonite clay and sand. Out of these four components, the biggest part is that of the sand. There are several proportions of these four components. The different ratios are used to adjust the surface finish, moldability and capacity of the hot molten metal to degas. The prime use of this sand is in the metal casting. The coal is usually called as sea coal in foundries. The amount of sea coal is less than 5 percent. It undergoes partial combustion when there is molten metal present and this causes offgassing of organic vapors. Green sand is stored in flasks (as the casters call the container). These are boxes that do not have a bottom or lid. This box is divided into two half parts and these are connected together. These halves are called as the top or cope and bottom or drag flask. As per its name, green sand is not green in color. The word “green” is used as it is used in the wet state. Casting Sand: Some casting sands are oil bonded and foundry mix sand. This is a mixing of oil, resin and sharp fine silica sand. Such a mix can be utilized in sand casting of all varieties of metals. Some casting sands consist of 20 percent more oil and resin as compared to other brands. The objective is to ascertain the best mix for maximum green power and the best finish for the surface, that is possible. The oil bonded sand is a substitute for water bonded green sands to be used for casting sand. The advantage over traditional, older sands is that as water is absent, the sand does not steam like the traditional sands. This sand is more secure to use than green sand. The reason is that potentially explosive quantities of steam are not generated. Due to this dearth of steam generation and the smooth texture of the sand, the oil bonded sand results in a smoother surface finish. The novice can use these sands and get professional results. Use of casting sand: The same techniques, patterns and tools that are used for water bonded sands can be used for oil bonded casting sands. As the sand has better adhesive properties, there are fewer hassles with loose sand in the impression. The difference is that water cannot be used to manage loose sections. However, as the self adhesion is better, there are fewer problems of crumbling. When the oil comes in contact with molten metal, it does not burn. When the castings are being shaken out, it is advisable to take off the sand that is burned. This sand that is burned can then be mixed again in the pile of fresh sand. It reabsorbs oil and works very well. After repeated use of this sand, the oil gets depleted. In this case, around 30W of non-detergent motor oil can be used to reload the sand with oil. |
| Information On Resin Casting And The Process Of Resin Casting Resin Casting is a system of technical installation that is used in the process of casting resin. The process of Resin Casting is a complex process that is used in a variety of fields. The resin casting giver a high quality and precision to the product that is casted. Need for Resin Casting: Resin casting is used to obtain a high level of quality and also precision in the dimensions of the product. Resin casting is basically used in the process of miniaturization i.e. the process of making things small. The process of Resin Casting is also used extensively the field of electronics. The electronics industries today resort to the resin castings to achieve the norms of total quality management. The process of resin metal casting earned success and also gained popularity in the field of electronics because it facilitated the acute miniaturization process and also at the same time maintained a high level of quality. The electronics industry is a very demanding field in terms of quality and cost. Experts recommend that the process of resin casting is an ideal way to achieve the required quality and it also helps cut down the cost of production. The process is also highly productive and also reliable with respect to speed. Industrial Applications of Resin Casting: The process of resin casting is basically used in the electronics industry. Resin Casting is used in the production of transformers, Liquid Crystals Displays more commonly known as the LCD’s. It also used in the manufacture of heavy electronic systems. Important steps in Resin Casting: The process of resin casting is completed in basically five important steps. The first step is to condition the resin, and then the material is transported. After the transportation of the material the three most important steps are executed. First the material is metered, then the material is mixed and then finally it is dispensed. Conditioning process: The process of conditioning in the resin casting evenly distributes the fillers ion the mixture. The conditioning also eliminates the moisture and air. It also makes the mixture constant, and also elevates the temperature of the mixture. The process of conditioning also maintains a low viscosity in the mixture. This process is very important for complex combinations as it intensifies the quality of the product. Process of Material Transportation: In the process of transportation of the materials, the piston pumps, screw pumps, and the gear pumps are used. For the highly viscous substances, instead of gear pumps, follower plate pumps are used. Mixing process: The process of mixing is extremely important as it obtains an equal and stabilized reaction through all the materials. The most commonly used methods in the mixing are the static mixing tube, the dynamic blender, and the dynamic static mixing tube. Dispensing process: The process of dispensing is the most important process in the Resin Casting. In the dispensing process the dispensing unit and the movement of the part are relative to each other. Resin is casted through various dispensing processes like the metering systems, or sometimes the dispensing is done in a vacuum. In the industrial to cut costs and also time multiple dispensing units are used. |
| Metal Casting Information And Basic Metal Casting Information Casting can be defined as a process of manufacturing, which implies pouring of a ‘liquid’ material into ‘A Mold’ containing a desired shaped hollow cavity, and then made to solidify. The ejection or breaking out of the casting then takes place to get the process completed. The use of casting is ‘forming hot liquid metals’ or numerous metals that are cooled after having the components like clay, plaster, concrete, and epoxies mixed. Complex shapes are normally made by casting, as other methods are not feasible. Casting came into being around 6000 years ago. ‘Copper Frog’ is the most ancient casting existing till date since 3200 BC. The process of casting has two distinct subdivisions: non-expendable and expendable mold casting. ‘Non-expendable’ mold casting: This technique is inclusive of at least 4 distinct methods: continuous, centrifugal, die, and permanent casting. Continuous casting: Continuous casting can be defined as a refined process of casting for high-volume, continuous production of ‘metal sections’ with constant cross-section. The pouring of molten metal into a water-cooled, open-ended copper mold takes place. This allows a ‘layer’ of ‘solid metal’ to be formed above the ‘still-liquid’ center. Continuous casting is widely accepted due to its cost-effectiveness. The metals continuously cast are aluminum, copper, and steel. Centifugal casting: Centrifugal casting is independent of both-pressure and gravity. This is because its own ‘force feed’ is created by the way of using a ‘temporary sand mold’ in ‘spinning chamber’ at 900 N. Lead time is variant with respect to application. True- and semi-centrifugal processing allow 30 to 50 pieces/hr. The batch processing has an upper limit of around 9000 Kg (practically). This method used to be applied for ‘Casting of Railway Wheels’. It was developed by the company called ‘Krupp’. It had a German origin. Jewelry is normally cast by this method. Die-casting: Die casting can be defined as a process of ‘forcing molten metal’ into cavities of mold under high pressure. These castings comprise of nonferrous metals, especially-alloys of aluminum, copper, and zinc. It is even possible to make die castings of metal. The method of die casting is used where finer parts are needed. ‘Permanent Mold Casting’: This casting is made up of non-ferrous metals. It requires some time to set up (some weeks), after which the production rate of about 5 to 50 pieces/hour-mold is achieved. The coating of ‘acetylene soot’ is applied to steel cavities. This helps in removing the work piece easily and promoting longer life (of tools). Permanent molds possess a limited life span. For worn molds, replacement or refinishing is required. Expendable mold casting: ‘Expendable Mold casting’ can be referred to as a standard classification inclusive of the following: Sand casting: It is amongst the simplest and most popular casting types used since ages. It involves very small size operations. The bonding of sand takes place by use of clays (as in ‘green sand’) or ‘polymerized oils’, or ‘chemical binders’. Recycling is easily possible. Plaster casting (for metals): There is no difference between plaster casting and sand casting, except the fact that plaster is used in place of sand. Similarly, there are also plastic and concrete castings. |
| Metal Casting Furnaces And Metal Casting Furnace Types Described There are several types of casting furnaces which include Electric Arc furnaces, Blast furnaces, Cornwall Iron Furnace, etc. Here’s a quick review of some of them. Electric Arc Furnace: This furnace can be described as a furnace heating charged materials by the way of an electric arc. These furnaces exist in all the sizes-right, from the smallest one having a capacity of around 1 ton to the largest one having a capacity of 400 tons. The former one is used in foundries to produce cast iron products, whereas the latter one is used for secondary steel making. The ones used by dentists and in research laboratories might be having capacity of a few grams only. The electric arc furnace can have temperatures risen up to 1800 Celsius. The first electric furnaces came into being in 1907, at the hands of Paul Heroult of French origin. The commercial part of these furnaces was established in the United States of America. In the beginning, the specialty product used in the making of spring steel and machine tools was electric steel. Calcium Carbide was also prepared in these arc furnaces. It (calcium carbide) was used in carbide lamps. This furnace comprises of a refractory-lined vessel, normally water-cooled in huge sizes, having a covering of a retractable roof, through which the entry of graphite electrodes takes place. They might be one or many in number. The furnace is divided into 3 sections: the shell, consisting of lower steel bowl and sidewalls, the hearth, consisting of refractory lining the lower bowl, and the roof, that can be water-cooled or refractory-lined, and can easily be shaped into a spherical section or conical section (frustum). A refractory delta is also supported by the roof at its center, by the way of which graphite electrodes make an entry. The process of operation starts with delivery of scrap metal to scrap bay which is located adjoining melt shop. After that, the loading of scrap into huge buckets or baskets takes place. The next step is to carry this basket to the melt shop. The charging takes place here. After the completion of charging, let the electrodes be allowed to enter and placed onto scrap. This causes the arc to be struck. Lower voltage is preferred for this part (of operation) to provide protection to the walls and roof against arc damage and excessive heat. After having the electrodes reached the heavy melt, shielding of arcs by scrap takes place. This enables a rapid formation of molten pool, thereby decreasing tap-to-tap times. Oxygen is also allowed to enter. Blast Furnace: It can be referred to as a kind of metallurgical furnace, through which the process of smelting takes place. This produces metals, normally iron. These furnaces trace their origin to China (around 500 BC). They were also found in Belgium and England later. They do not have any special mode of operation. The metals get melted by heating only. Generally, iron is melted in these furnaces. The chemical reaction can be explained as follows: Fe2O3 3CO -> 2Fe 3CO2 |
| Injector Torch, Cutting Torch, And Other Metal Casting Torches Described Oxy-fuel cutting and oxy-fuel welding can be described as the processes of using oxygen and fuel gases to either cut or weld metals. There are some striking differences between these two processes. In the first process, a cutting torch is made use of for heating ferrous metal to a temperature of around 980 degree Celsius. An oxygen stream is being trained on a hot metal that combines with iron chemically which later flows from the kerfs, or cut in the form of slag of iron oxide. In the second process, a ‘welding torch’ is made use of for welding metals. Torches that burn the inside fuel with air (atmosphere) cannot be termed as oxy-fuel torches. They stand out owing to the use of single tank. This is because oxy-fuel cutting/welding requires oxygen, fuel, and two tanks. It’s not possible to melt some of the metals with single-tank torches. Hence, these torches can be used for brazing and soldering, but not for welding. A metal-cutting torch is better known as hot blue spanner, blue wrench, hot wrench, smoke wrench, and gas-axe. Types of Torches: The torch can be defined as the part held and manipulated by the welder to get the weld made. It possesses a valve and connection for oxygen and the same things for fuel gas, a handle to obtain the grip, an integrating chamber (angularly set) where there occurs a mixing of oxygen and fuel gas, with a tip where formation of flame takes place. The fuel gases used along with oxygen include propylene, propane, hydrogen gas, MAPP gas, Liquefied Petroleum Gas (LPG), and the most widely used is acetylene. Injector Torch: It can be defined as an archetypal oxy-fuel torch, also known as an equal-pressure torch. It carries out the mixing of mere two gases. The injector torch operates in such a way that high pressure oxygen comes out of the tiny nozzle present in the torch head, and the fuel gas gets dragged towards it via the venturi effect. Rose-bud Torch: The use of this torch is to carry out the heating of metals for straightening, bending, etc. It is generally used where a huge area requires heating. It produces a rose-bud shaped flame at the end, hence the name. This torch can carry out the function of heating small areas like rusted bolts and nuts as well. However, here, filler rod won’t be used with torch. Cutting Torch: The head of the cutting torch is used for cutting metal. Its identification details are as follows: The inside of the torch consists of a combination of oxygen and acetylene. It helps in producing flame of a high temperature. It consists of 3 pipes going to a nozzle at 90 degree. It also contains an oxygen-blast trigger which blasts away the material during its cutting by the way of providing oxygen. Welding Torch: The welding torch consists of either 1 or 2 pipes running towards the nozzle without oxygen-blast trigger. As the name suggests, it performs the function of welding. |
