摘要/Abstract

摘要： 以用后高铝砖和渣钢粒铁为主要原料，高铝水泥为结合剂制备了转炉无碳挡渣锥，研究和分析了耐火粒子、渣钢粒铁和轻烧镁砂粉对挡渣锥性能的影响。研制的新型无碳挡渣锥在酒钢碳钢120 t转炉、不锈钢110 t脱磷转炉、碳钢50 t转炉成功应用10 000余支，挡渣成功率达到了99%以上，使用效果良好。冶金固废代替了转炉挡渣锥中80%以上的优质原料，大大降低了钢铁冶炼成本，同时减少了固体废物的排放，具有良好经济效益和社会效益。

Abstract:

Carbon-free skimming cones of converter were prepared with used high alumina bricks,slag steel and iron grit as main starting materials,high alumina cement as binder.The effects of refractory grain,slag steel and iron grit and light burned magnesia on the performance of skimming cones of converter were studied and analyzed.More than 10 000 novel carbon-free skimming cones have been successfully applied to 120 t carbon steel converter,110 t stainless steel dephosphorization converter and 50 t carbon steel converter of Jiu steel.The success rate of skimming was over 99% and the application effect was good.Metallurgical solid waste has been replaced more than 80% of high quality raw materials in skimming cone of converter,greatly reduced the cost of iron and steel smelting,and reduced the discharge of solid waste,with good economic and social benefits.

Key words: Metallurgical solid waste, Skimming cone of converter, Environmental protection
