Description

technical field [0001] The invention provides a composition conditioning material suitable for blast furnace slag glass-ceramics and a conditioning method thereof, belonging to the technical field of glass-ceramics preparation. Background technique [0002] Blast furnace slag is the accompanying product discharged from the blast furnace when the pig iron is smelted. When the furnace temperature reaches 1400-1600 ° C, the furnace charge melts, and the gangue in the ore, the ash in the coke, the co-solvent and other impurities that cannot enter the pig iron are formed. Slag mainly composed of silicate and aluminate floating on the molten iron. Blast furnace slag contains a large amount of "sensible heat" and "basic inorganic slag". However, as a high-quality waste heat resource, the efficient utilization of blast furnace slag has always been a problem that the iron and steel industry has paid close attention to. CaO, SiO in blast furnace slag 2 、Al 2 o 3 The total amount o...
