摘要
为了充分利用我国含砷铁矿资源,采用精炼渣+不同Ca合金对钢液进行脱砷研究,获得较高的脱砷率,其中Si-CaBa合金综合脱砷效果最佳.在相同操作条件下,通过改变实验条件,对钢液中砷含量随时间变化规律以及对脱砷效果的影响进行研究,并对高砷含量下不同Ca合金加入钢液后Ca的有效利用率进行详细分析.
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.
