PROCESS FOR PRODUCING CHROMIUM CONTAINING MOLTEN IRON |
摘要 |
<p>A process of production of chromium containing molten iron generally comprises two steps. In a first step, top and bottom-blow injection is performed with charging carbon containing material and slag forming agent from the top of a converter for melting stainless scrap and for rising temperature of molten iron bath.
