METHOD FOR MAKING STEEL

摘要

The method for making steel from solid metal Fe-bearing materials, particularly from scrap material, in an oxygen converter provides for heating and melting solid metal Fe-bearing materials by the bottom- and lateral-blown fuel and oxidizer feed, which is effected upwards and sideways across the thickness of the metal materials charged into the converter, and by the top-blown oxidizer feed. Then the metal melt is refined and a silicon-containing and heat-conveying material is added thereinto simultaneously. At the same time the lateral and top-blown oxidizer feed is discontinued and the bottom-blown oxidizer feed is reduced.
