The use of induction heating as an alternative to gas or oil fired heating for the fire, refining of precious metals is attractive for several reasons: (1) compactness, (2) less waste heat, therefore cooler room temperatures, (3) cleaner operation, (4) no off-gas discharge, (5) energy efficient as less material heated and (6) less time to reach temperature.
A process for refining steel in induction furnace comprising steps of: (a) providing an induction furnace having basic or neutral refractory lining; (b) providing slag having basicity of the order of 1.5 to 4; and (c) maintaining iron oxide content (FeO) of slag in the induction furnace for continuous oxidation and removal of phosphorus from slag.
content in the slag. During the induction furnace process due to low slag basicity and low slag volume sulphur removal is not present. Due to the lack of refining capability with induction steelmaking process, induction furnaces are mainly present in rebar production with required carbon
The Induction Furnace is an advanced version of the Electric Furnace. It has the ability to process 2 stacks of items simultaneously. Doing so will also save 50% of the energy that would have been used had every stack been smelted by itself. Another feature of the Induction Furnace is its ability to build up heat.
Induction slag melting (ISM) was developed by the Bureau in the 1970's as a technique for vacuum induction melting titanium in a segmented copper crucible. Its original intent was to consolidate titanium castings revert and loose titanium scrap into electrodes for melting in consumable-arc furnaces.
