The role of lime in steelmaking: lime powder desulfurization plant in steelmaking, especially in basic electric arc furnace plant desulfurization Buying powder, mainly used for "slagging agents" supply plant desulfurization powder, removal of harmful elements in the molten steel S , P and other impurities, optimized steel quality. Power generated in the steelmaking slag desulfurization slag powder can sell, the main component of (4CaO · P2O5) and (CaS), continuous removal of the slag from molten steel process to achieve the purpose of removing sulfur and phosphorus. The main factors affecting the quality of the lime burning: calcining kiln choice. Calcining kiln rational structure for the production of "light burning" lime to create conditions for the fire point uniform distribution, logistics, and each segment proper temperature control, the effect is like firing. Other factors. Charge mode of operation, feeding, ash and kiln seal way, automatic control production levels, technical quality of workers and the like.
