Abstract

Abstract

To make full use of Chinese symplesite resources,refining slags and different Ca alloys were added to molten steel as dearsenization agents in the experiment. The Si-Ca-Ba alloy showed the most obvious dearsenization effect. Under the same operation conditions,the change of arsenic content in molten steel was investigated by changing experimental conditions,and the influences of experimental conditions on the dearsenization effect were discussed. Simultaneously,the utilization ratio of Ca after adding different Ca alloys to molten steel at high arsenic content was discussed in detail.
