composition for reducing the eisenoxidbildung in slag from steel melts, and process for the production of a slag with low iron oxide content or

摘要

A composition comprising: from 50 to 60 wt-% of C, from 7 to 10 wt-% of Al, from 15 to 20 wt-% of Al2O3, from 7 to 10 wt-% of CaO and from 2 to 5 wt-% of MgO. A process for preparing such compsitions as well as a process for using such composition in the melting of scrap iron in a electric furnace with the aim of decreasing iron losses due to oxidation and of lowering iron oxide content of steel melting slag.
