RESEARCH AND PRACTICE ON INFLUENCING FACTORS OF Cr2O3 CONTENT IN SLAG OF LARGE-CAPACITY FERROCHROME SUBMERGED ARC FURNACE
The article researched relation between Cr2O3 in slag and parameters,such as chrome ore properties,slag composition,slag basicity,MgO/Al2O3 ratio,silicon content in alloy,etc.At the same time,used data analysis soft-ware Mintab to clarify the order of priority among those factors.There by purposefully optimized and adjusted the origi-nal process parameters.Eventually Cr2O3 content in slag was effectively reduced and the chromium recovery rate of was raised.
