PROCESSO PARA AUMENTAR AS PROPORCOES DE ADICAO DE MATERIAIS FRIOS NA FABRICACAO DE ACO POR SOPRAGEM DE OXIGENIO

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.
