摘要
以高纯烧结镁砂和电熔镁砂为主要原料研制出了具有良好物理性能、施工性能、抗爆裂性能和使用性能的挡渣墙用镁质浇注料。探讨了养护温度、养护时间和环境湿度对坯体性能的影响。在某钢厂 4 8t中间包中的实际使用结果表明 ,镁质挡渣墙对钢水中CaO、SiO2 和A2
Using high purity sintered magnesia and fused magnesia as main raw materials,magnesia based slag dam was developed with good properties and explosion resistance.The influences of cure temperature,cure time and ambient humidity on the properties of the dam blank were discussed.The slag dam was successfully used in the 48 t tundish. The studies on the residual dam showed that the dam could absorb impurities such as CaO,SiO 2 and Al 2O 3,so it has the function of purifying molten steel.
