1963年11月上旬,辽宁省金属学会在抚顺市召开了耐火材料学术会议。参加会议的有全国18个单位的耐火和炼钢工作者代表43名。会上提出有关耐火材料生产等方面的论文18篇。会议着重对铸锭用耐火材料的损毁原因和提高质量的方向进行了讨论。(一)盛钢桶衬砖。经过讨论后认为盛钢桶衬砖的损毁,主要是在高温下受到钢渣和钢水的侵蚀与冲刷,在砖的某些薄弱部位和砖缝处首先被破坏而逐渐扩大。有些同志还认为衬砖受到的温度激变,也是导致损毁的一个原因。为此,提出了以下 In early November 1963, Liaoning Metals Society held a refractories conference in Fushun City. Attending the meeting were 43 fire and steelmaking workers representing 18 units across the country. At the meeting on the production of refractories 18 papers. The conference focused on the reasons for the damage of the refractory material for ingot and the direction of improving the quality. (A) Sheng steel bucket lining brick. After discussion, it is considered that the damage of the steel lining brick is mainly caused by the erosion and erosion of the steel slag and the molten steel at high temperature, and is gradually expanded in some weak parts and brick joints of the brick. Some comrades also consider that the temperature change in lining bricks is also one of the causes of the damage. To this end, the following is proposed
