摘　　要：介绍了转炉气动挡渣的原理以及该设备在包头钢铁(集团)有限责任公司120t转炉上的使用情况。应用初期,存在钢渣粘结并需要人工处理的情况,通过选用合适的喷涂材料,解决了这一问题。该技术使转炉下渣平均厚度由原来的97.3mm降低到46.9mm,不仅减少了钢水回磷,而且提高了合金的收得率,给企业带来了明显的经济效益。The principle of technology about blocking BOF slag by gas and actual results of application of the slag blocking equipments in the 120 t converter in Baotou Iron ＆ Steel （Group） Co. , Ltd. are described. In the initial stage problem of slag adhesion occurs and it has to be eliminated manually. The problem is finally solved by painting proper paint material. By adoption of this technology the average thickness of exhausted slag is reduced to 46.9 mm from the original 97.3 mm. As the results not only the phosphor pick-up is decreased but also the yield of alloy elements increased. Thus prominent economical efficiency has been achieved.
