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. In order to make full use of arsenic resources in our country, refining slag + different Ca alloys were used to study arsenic removal of molten steel to get a higher arsenic removal rate, of which Si-CaBa alloy had the best arsenic removal effect. Under the same operating conditions The change of arsenic content in molten steel over time and its effect on arsenic removal were studied by changing the experimental conditions. The effective utilization of Ca after adding different Ca alloy into molten steel under high arsenic content was analyzed in detail.
