A cupola or cupola furnace is a melting device used in foundries that can be used to melt cast iron, Ni-resist iron and some bronzes.The cupola can be made almost any practical size. The size of a cupola is expressed in diameters and can range from 1.5 to 13 feet (0.5 to 4.0 m). The overall shape is cylindrical and the equipment is arranged vertically, usually supported by four legs.
a blast furnace byproduct from pig iron production. Other sources of slag include the copper, lead, and phosphate industries. The production process has 3 primary components--molten mineral generation in the cupola, fiber formation and collection, and final product formation. Figure 11.18-1 illustrates the mineral wool manufacturing process.
Cupola furnaces are tall, cylindrical furnaces used to melt iron and ferrous alloys in foundry operations. Alternating layers of metal and ferrous alloys, coke, and limestone are fed into the furnace from the top. A schematic diagram of a cupola is shown in Figure.
Blast Furnace. After mining, various kinds of iron ores are brought to the blast furnace which is the starting process for refining iron ores or mined ores and for the production of pig iron.Blast furnace was invented in 14th century. A typical blast furnace along with its various parts is shown in Fig. 1.

Jan 06, 2018· Cupola Furnace is a melting device used to melt cast iron, Ni-resist iron, and some bronzes and It is used in Foundries. The cupola can be made of any size and the size of the cupola is measured in diameters which range from 1.5 to 13 feet.
John Campbell, in Complete Casting Handbook (Second Edition), 2015. The cupola; a shaft furnace for iron. Iron foundries have had the benefit of such a furnace for many years in the form of the cupola.Because the melted iron passes over a deep bed of incandescent coke, it can be heated to a high temperature if necessary.
flow at the center of the furnace. To achieve this, the ore to coke weight ratio (O/C) has to be maintained lower locally at the center. This is done by adjusting the weight ratio of ore and coke around the radius at the time of charging both the materials from the top of the furnace.
