BACKGROUND REPORT AP-42 SECTION 12
Furnace Operations The three most common furnaces used in the iron foundry industry are cupolas, electric arc, and electric induction furnaces. The cupola is the major type of furnace used in the iron foundry industry. It is typically a cylindrical steel shell with a refractory-lined or water-cooledInduction furnace - Wikipedia,An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal. Induction furnace capacities range from less than one kilogram to one hundred tonnes, and are used to melt iron and steel, copper, aluminum, and precious metals.. The advantage of the induction furnace is a clean, energy-efficient and well-controllable melting process compared to most,Gold Smelting & Metal Melting Equipment - 911Metallurgist,Oxidizing conditions were intensified by using oxygen and additional air. A charge of pig iron containing, in percent, Fe 89.3, Si 5.1, C 3.8, P 0.19, and S 0.01 was melted in a zirconium silicate crucible by induction heating. Limestone, to the extent of 20 percent of the charge weight, was placed on the molten metal at 1,350° C.
