studentsrepo.um.edu.myIn foundry, cast steel is typically melted in electric arc furnaces or coreless induction furnaces. However, there are several kinds of furnaces that are being utilized. The cupola furnace is the common furnace used for cast iron melting and the oldest type of furnace used in foundries. The cupola process produces a
12.5 Iron And Steel Production - US EPA
www3.epa.gov12.5.1.5 Steelmaking Process — Electric Arc Furnace - Electric arc furnaces (EAF) are used to produce carbon and alloy steels. The input material to an EAF is typically 100 percent scrap. Cylindrical, refractory lined EAFs are equipped with carbon electrodes to be raised or lowered through the furnace roof. With electrodes retracted, the ...
4 FURNACES - Bureau of Energy Efficiency
beeindia.gov.inmajority of the furnaces use liquid fuel, gaseous fuel or electricity as energy input. Melting furnaces for steel, cast iron use electricity in induction and arc furnaces. Non-ferrous melting utilizes oil as fuel. Oil Fired Furnace Furnace oil is the major fuel used in oil fired furnaces, especially for reheating and heat treatment of materials.
