Abstract：To make full use of domestic iron ore containing arsenic， the dearsenication agent of Si-Ca-Ba alloy＋CaF2 were researched in laboratory. It has been shown that the ratio of Si-Ca-Ba alloy， temperature， the amount of dearsenicatior and initial sulfur content in molten steel can affect the results of dearsenication. The present results indicate that the ratio of Si-Ca-Ba alloy which is in the range of 65%-75% has the most obvious dearsenication effect. Simultaneously， elevating temperature of molten steel， increasing the amount of dearsenication agent and reducing the initial sulfur content can improve the rate of dearsenication..
