Induction Furnace- A Review

Non-uniform flame distribution, Oxidation of metal, Scale formation and Emission of pollutants are the various major problems found in oil-fired and coal-fired furnaces. Both of these furnaces have low productivity and longer start-up time. The development of Industrial induction furnaces has taken place over a period of last 25 years. So, these problems can be avoided by using the new technology induction furnace. Present practices followed in Induction Furnaces are discussed in this paper. Due to non-availability of the proper instrumentations the effect of the ill practices cannot be precisely judged. If this is properly measured, the percentage of productivity improvement in steel melting Induction Furnace can be calculated
