METHOD OF INCREASING THE COLD MATERIAL CHARGING CAPACITY IN THE TOP-BLOWING PRODUCTION OF STEEL

摘要

Pig iron is refined by top blowing with oxygen and injecting inert gas from the bottom. The slag formation is minimized by controlled addition of lime to match the formation of slag components as they are generated by the process. This increases the capacity of the melt to receive a cold charge, e.g. of scrap.
