Induction Furnace - A Review

A new generation of industrial induction melting furnaces has been developed during the last 25 years. Present practices followed in Induction Furnaces are discussed in this paper. Through a literature review account of various practices presently being followed in steel industries using Induction Furnaces has been carried out with a view to gather principal of working. Apart from this a pilot study has also been carried out in few industries in India. We provide some recommendations for the productivity improvement .Due to non availability of the proper instrumentations the effect of the ill practices can not be precisely judged. If this is properly measured, the percentage of productivity improvement in steel melting Induction Furnace can be calculated.The review is carried out from the literature in the various journals and manuals.
