Verfahren zur Herstellung von chromhaltigem, flüssigem Eisen.

摘要

A process of production of chromium containing molten iron generally comprises two steps. In a first step, top and bottom-blown reduction for reducing chromium 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. In a second step which is performed subsequently to the first step, top and bottom-blow injection with charging chromium oxide and carbon from the top of the converter for reduction of chromium.
