半钢炼钢加块状含碳材料补充供热试验

Trial on Addition of Lumpy Carbon Containing Material as Supplementary Heat Source in Making Steel with Semi Steel Charge

本文介绍马钢二炼钢厂20t转炉添加块状含碳材料补充供热的试验情况,解决了半钢炼钢热源不足问题,从而使钢质量提高,废钢比增加及显著的经济效益。

The present paper reveals the detail of production trial on adding Lumps of carbon containing material to the 20-tonne oxygen-blown converter as su- pplementary heat source by No. 2 Steel Plant in Ma An Shen lron and Steel Co- mpany. Results of the test show that heat source shortage in steel making of oxygen converter with semi steel is adequately compensated, steel Guality improved, and scrap ratio increased by using the method, thus marked economic effect has been achieved.
