Abstract

Abstract

To make full use of symplesite resources in China,CaO + CaF₂,CaC₂+ CaF₂ and Si-Ca-Ba alloy + CaF₂ were used as an agent in molten steel dearsenization experiment. The Si-Ca-Ba alloy + CaF₂ agent shows the most obvious dearsenization effect.Their dearsenization rate is as high as 67.7%. Under the same operation conditions,the effects of temperature,mass transfer coefficient and S content on the dearsenization of the three dearsenization agents were analyzed and compared by laboratory research.
