Magnesia carbon brick for ladle slag line capable of resisting high-alkalinity slag corrosion and preparation method thereof
The invention provides a magnesia carbon brick for a ladle slag line capable of resisting high-alkalinity slag corrosion and a preparation method of the magnesia carbon brick. The magnesia carbon brick is prepared from the following raw materials in percentage by mass: 70-80% of fused magnesia, 6-16% of crystalline flake graphite, 1-8% of silicon powder, 0.08-4% of aluminum powder, 1-10% of an additive and 2-8% of thermosetting phenolic resin. The additive is a mixture of high-temperature asphalt powder and zirconium plate powder in a mass ratio of 1:(1.5-2.5). According to the invention, theton steel consumption of the magnesia carbon brick for the ladle slag line can be obviously reduced, so that the service life of the ladle slag line brick is longer; the melting loss rate of the refractory lining material for the slag line of the steel ladle built by the slag line brick is lower, so that the ton steel consumption of the refractory material for the slag line of the steel ladle canbe obviously reduced, and the service life of the slag line brick of the steel ladle is longer.
本发明提供一种抗高碱度渣侵蚀钢包渣线用镁碳砖及其制备方法，由下述质量分数的原料制成：电熔镁砂：70%～80%，鳞片石墨：6%～16%，硅粉：1%～8%，铝粉：0.08%～4%，添加剂：1%～10%，热固性酚醛树脂2%～8%；所述添加剂为质量比为1：（1.5～2.5）的高温沥青粉和锆板粉的混合物。本发明能明显降低钢包渣线用镁碳砖的吨钢消耗，使钢包的渣线砖使用寿命更长；该渣线砖砌筑的钢包其渣线用耐火衬料熔损速率较低，能明显降低钢包渣线用耐材的吨钢消耗，使钢包渣线砖的使用寿命更长。
