Magnesia carbon brick for smelting low-alkalinity slag
The invention discloses a magnesia carbon brick for smelting low-alkalinity slag and a preparation method of the magnesia carbon brick. The magnesia carbon brick is prepared from the following raw materials in percentage by mass: 60 to 80 percent of fused magnesia, 10 to 20 percent of fused magnesia-zircon sand, 10 to 14 percent of graphite, 2.5 to 3.5 percent of liquid resin, 0.5 to 2 percent ofcarbon-containing resin powder and 0.3 to 1.0 percent of boron carbide powder. The magnesia carbon brick provided by the invention has good slag corrosion resistance to low-alkalinity slag, and the service life of a magnesia carbon brick furnace lining can be effectively prolonged.
本发明公开了一种冶炼低碱度渣用镁碳砖及其制备方法，本发明的镁碳砖包括以下质量百分数的原料：电熔镁砂60％～80％、电熔镁锆砂10～20％、石墨10％～14％、液态树脂2.5％～3.5％、含碳树脂粉0.5％～2％、碳化硼粉0.3％～1.0％。本发明提供的镁碳砖对低碱度渣具有良好的抗渣侵蚀性，可以有效的镁碳砖炉衬的使用寿命。
