摘　　要：国内很多钢厂大中型转炉采用滑板挡渣出钢技术,配套的出钢口砖成为影响滑板挡渣工艺发展的因素之一。本文对滑板挡渣出钢口砖的应用情况进行分析,研究损毁原因后提出优化改进措施。新研制的高寿命滑板挡渣出钢口砖具有很好的应用效果。Many large and medium-sized converters in domestic steel plants began to adopt sliding gate slag-blocking tapping technology. The supporting tap hole bricks have become one of the factors affecting the development of the sliding gate slag-blocking technology. In this paper,the application of the sliding gate slag-blocking tap hole brick is analyszed,the damage reason is studied and the improvement measures are put forward. The improved and developed long-life tap hole brick has a good application effects.
