为了充分利用我国含砷铁矿资源，采用CaO+CaF2、CaC2+CaF和Si-Ca-Ba合金+CaF2对钢液进行脱砷研究，获得较高的脱砷率，其中Si-Ca-Ba合金+CaF2脱砷效果最明显，其脱砷率最高可达67.7%.在相同实验操作条件下，通过实验室研究，分析比较了温度、传质系数和S含量对不同脱砷剂脱砷效果的影响.

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 coeffi-cient and S content on the dearsenization of the three dearsenization agents were analyzed and compared by laboratory research.
