Abstract

PURPOSE: To obtain electric power sufficient for refining by presmelting ore in a rotary converter using coal as fuel and an oxygen lance, gathering the generated gas, and utilizing power generated by the energy of the gas in the reducing process of a refining furnace.
CONSTITUTION: Ore is presmelted by melting or melting and partial reduction in a rotary converter 1 using coal from a burden feeder as fuel and an oxygen lance 2. Gas generated during the presmelting is passed through a wet venturi 4, freed of dust with a cyclone 5, and burned with a boiler 9 to produce steam. A power generator 12 is worked by the steam to generate power, and this power is supplied to a plasma arc furnace 14 through a substation 13. In the furnace 14 the molten oxide from the converter 1 is reduced.
