What Are the Uses of Blast Furnace Slag (BFS)? FTM

12-12-2019 · When pig iron is smelted in a blast furnace, the flux is added to the raw materials from the blast furnace in addition to iron ore and fuel (coke). When the furnace temperature reaches 1400-1600 ℃, the lime in the flux reacts with the aluminate, silicate and coke ash in the ore at high temperature and chemically combines to form a nonmetal product called blast furnace slag.
