Abstract

A process for the production of molten crude iron and reduction gas is described wherein the molten iron and gas are formed in a smelting gasifier, to which is introduced at the upper portion thereof preheated sponge iron of particle size between 3 mm and 30 mm and coal to form a fluidized bed, and an oxygen-containing gas at the lower portion thereof, and controlling the ratio of oxygen-containing gas and coal to maintain a high temperature zone in the lower portion of the gasifier and a lower temperature zone in the upper portion thereof, the oxygen-containing gas being introduced substantially immediately above the resulting melt which is formed at the bottom of the gasifier.
