Current Situation and Development Trend of Electric Furnace Slag Treatment Technology
Against the background of increasing emissions of steel slag from electric furnaces,the treatment technology of electric furnace slag is very necessary.Based on the composition of electric furnace slag from a certain factory in the north,it analyzes the quantity of free calcium oxide and magnesium oxide in steel slag.Due to the strong fluctuation of steel slag composition,the reuse technology of electric furnace steel slag is limited to some extent.At present,the utilization direction of electric furnace steel slag mainly includes the preparation of steel smelting flux and smelting raw materials,building materials,ecological improvement agents,and soil fertilizers.The latest research and development direction of electric furnace slag treatment technology mainly focuses on online processing of steel slag and waste heat recovery,including mod-ified electric furnace steel slag treatment process,slag iron hot separation and recovery process for matte phase enrichment and separation,col-laborative quenching and tempering treatment of steel slag and non-ferrous metal smelting slag,fluidized bed quenching steel slag treatment process,disc electric furnace steel slag treatment process,and horizontal vibration pressure hot soaking steel slag treatment process.However,the sensible heat recovery technology of steel slag still needs further development and application in production practice.
