METHOD FOR PREPARING COMPOSITE MATERIAL FOR SINTERED ORE USING NICKEL SLAG PRODUCED AFTER REFINING NICKEL

摘要

PURPOSE: A method for preparing composite material for sintered ore is provided to recycle nickel slag as substitute for serpentine, forsterite, or dolomite, thereby obtaining high quality sintered ore ensuring high strength at room temperature.;CONSTITUTION: A method for preparing composite material for sintered ore comprises a step of adding moisture to a powder material for sintered ore, which includes fine ore, a SiO2-containing material, a limestone-based powder material, and a solid fuel based powder material and assembling the powder material using water as a cross-linking agent, wherein the SiO2-cotaining material employs nickel slag.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Room-temperature strength(SI,%); (BB) Ni-Slag usage ratio(%)
