SYNTHETIC SLAG USED FOR ADJUSTING THE SIO2 CONTENT OF SLAG IN THE PRODUCTION OF HIGH CARBON FE MN IN SUBMERGED ARC FURNACE (SAF)

摘要

A process of producing synthetic slag used for adjusting the SiO2 content of slag in the production of high carbon FeMn in submerged arc furnace where in the quartz / quartzite fines or suitable materials. Containing high concentration of silica is mixed with stream of hot molten slag form FeMn operation and after coding; the mixture is rushed of lumps of required size for use.
