Application of active lime in molten steel refining

Date of release:2019-07-19 Author: Click:

Experiments have proved that adding appropriate amount of active lime and fluorite to the refined molten steel has achieved better results: eliminating slagging, slagging and top slag crusting in the ladle, and also eliminating the slagging of the impregnation cover and suction nozzle The active lime greatly reduces the thermal shutdown processing time of the ladle, dipping hood, and suction nozzle, reduces the radiation on the top of the refining furnace, and improves the service life of the ladle refractory and refined refractory; It improves the refined molten steel The basicity of the top slag reduces the melting point of the slag, improves the fluidity of the slag, and has a certain desulfurization effect on the molten steel. At the same time, it reduces the total amount of inclusions in the molten steel and improves the quality of the molten steel; it not only satisfies the production process The requirements ensured the smooth progress of production and created considerable economic benefits.
