ABSTRACT:
A furnace for the melting of ferriferous materials, namely, iron scrap, pig iron and sponge iron having a low oxygen content, is operated by the addition of coke to the charge so that the quantity of coke substantially is equal to that required to carburize the melt. A non-oxidizing gas heated by plasma torch is introduced into the melt to smelt the charge by direct transfer of sensible heat thereto. The method allows the use of renewable energy sources in place of the fossil fuels and other nonrenewable sources hitherto required to generate the thermal energy for melting.
