摘　　要：根据实验室对低氟碳酸盐熔渣发泡剂的研究结果,在宝钢100t冶炼不锈钢电弧炉上进行熔渣发泡性能的工业性试验。得出了所研制的发泡剂在不锈钢冶炼中具有良好的起泡性能,起泡性能与发泡剂加入方式、发泡剂粒度等有关。根据试验结果总结得出最优的加料方式,分析了发泡剂粒度对熔渣起泡性能的影响。On the basis of results of the laboratory study on the low fluoride carbonate foaming slag the industrial scale experiments on foaming behavior of the slag have been carried out in a 100 t EAF in refining stainless steel in Baosteel. Results show that the newly developed foaming agent has excellent foaming behavior, and the foaming behavior is related to the way of addition and the particle size of the foaming agent. The optimal way of the foaming agent addition is obtained by summarizing the experimental results and the influence of particle size on the slag foaming behavior analyzed in detail.
