高碳铬铁炉改炼硅钙合金实践

RPACTICE OF SMELTING SILICOCALCIUM IN HIGH CARBON FERROCHROMIUM ELECTRIC ARC FURNACE

为满足市场需求，将 0. 6MVA高碳铬铁矿热炉改造为 0. 6MVA硅钙电炉，采用分层加料法冶炼效果较好，不仅延长了炉龄，提高了品级率，降低了电耗和原料消耗，同时提高了元素回收率。

To meet the need of the market,0.6MVA HC FeCr electric furnace was transformed into 0.6MVA SiCa furnace.Smelting SiCa with layer by layer distribution method can prolong furnace life,increase rate of grade,reduce electricity and material consumption amd increase element recoverey,thus the smelting results are very good.
