Magnesia carbon brick added with spinel calcium aluminate particles
The invention provides a magnesia carbon brick added with spinel calcium aluminate particles. The magnesia carbon brick comprises the components in parts by weight: 55-80 parts of fused magnesia particles, 5-20 parts of fused magnesia fine powder, 5-15 parts of fused brown alumina particles, 5-10 parts of spinel calcium aluminate particles, 10-20 parts of graphite, 0.1-1 part of boron carbide, 1-5parts of silicon carbide, 1-5 parts of phenolic resin and 0.1-1 part of urotropine. According to the magnesia carbon brick added with the spinel calcium aluminate particles, the preparation method issimple, the steps are easy to operate, the spinel calcium aluminate particles are added into the raw materials of the magnesia carbon brick, the oxidation resistance of the magnesia carbon brick canbe improved, meanwhile, the corrosion resistance of the magnesia carbon brick is improved, the application performance of the magnesia carbon brick is improved, and the service life of the magnesia carbon brick is prolonged.
本发明提供一种添加尖晶石铝酸钙颗粒的镁碳砖，包括以下组份，各组分按重量份数计为：电熔镁砂颗粒55～80份、电熔镁砂细粉5～20份、电熔棕刚玉颗粒5‑15份，尖晶石铝酸钙颗粒5～10份、石墨10‑20份、碳化硼0.1～1份、碳化硅1～5份、酚醛树脂1～5份、乌洛托品0.1～1份。本发明提供一种添加尖晶石铝酸钙颗粒的镁碳砖，其制备方法简单，步骤易于操作，在镁碳砖的原料中加入尖晶石铝酸钙颗粒能够提高镁碳砖的抗氧化性，同时增加了镁碳砖的耐腐蚀性，改善了镁碳砖的应用性能，提高镁碳砖的使用寿命。
