The role of lime in steelmaking: Lime in steelmaking, especially in basic electric arc furnace, mainly used for "slagging agent", to remove harmful elements in the molten steel S, P and other impurities plant desulfurization powder manufacturers, optimizing steel quality. Slag generated in the steel-making slag, which is mainly composed of (4CaO · P2O5) and (CaS), continuous removal of the slag from molten steel process to achieve the purpose of removing sulfur and phosphorus. Lime traits: quicklime generally contain fire lime powder desulfurization plant offer, burned lime powder desulfurization plant quality slow ripening, maturation if the lime slurry and then hardening occurs due to expansion caused by aging resulting uplift and cracking. In order to eliminate this hazard burned lime, lime, after curing, but also "Chen V" about two weeks.
