| description | The invention relates to the technical field of steelmaking, in particular to an LF rapid desulfurization method of HPB300 plain carbon deformed steel bar. According to the corresponding relation between the C content of the argon station sample and the LF refining arrival oxygen, a corresponding amount of high-aluminum slag is added, so that good diffusion deoxidation efficiency can be obtained corresponding to different C contents, and desulfurization is promoted; and moreover, the high-aluminum slag is used for replacing a ferrosilicon powder deoxidizing agent on the silicon killed steel, so that the deoxidizing effect is obvious, the desulfurization speed is synchronously accelerated, and the labor intensity of workers is effectively reduced. Meanwhile, according to the rapid desulfurization method disclosed by the invention, the addition amount of lime and the corresponding strong stirring time are controlled according to the S content of the argon station sample, so that efficient desulfurization is ens |
