SIMPLE DISCUSSION ON THE ROLE OF MICRO CARBON FERRO-MANGANESE-SILICON IN "FOUR FURNACE LINKAGE"
This paper introduces the furnace,blast furnace,quenching and tempering furnace,refining furnace using blast furnace manganese slag or dust cold pressed pellets step take micro carbon ferromanganese-silicon and then full hot charging micro and low carbon ferromanganese production practice,namely on the basis of normal production of high carbon ferromanganese or refined ferromanganese in blast furnace or refining furnace,increasing a one-step pro-duction process for micro carbon ferromanganese-silicon,and with quenched and tempered blast furnace slag drawer shaking production ferromanganese-silicon(C<0.2%),eventually refining furnace hot charging production of micro and low carbon ferromanganese(Mn slightly lower).Through the"four furnace"capacity matching,and choosing the appropriate slag type and slag tapping temperature,iron tapping time,controlling the silicon and carbon content,and other technical measures,the utilization rate of silicon has been fully improved,thus forming a unique new quality pro-ductivity.
