Abstract:The production process of deoxidizing by CaC2 in BOF and LF refining furnace accompanied by feeding aluminum wire to compensate aluminum in LF can make full use of the deoxidation characteristics of CaC2 and aluminum, combine the diffusion deoxidation and precipitation deoxidation reasonably, improve the rate of aluminum, improving refining slag activity, leading to a good desulfurization effect of LF furnace and an improved economic benefit of aluminum steel.
