The perfect proportion of used binder and refractory was farther confirmed. According to this proportion room temperature strength, high temperature strength and residual strength were observed.
Therefore, if we retain about 10% of the heavy MgO after partial hydration, a high grade of refractory material can be obtained at a relatively lower temperature from the dolomite.
所以,部分水化后留下10%左右的重质氧化镁可以在较低温度下制得质量好的耐火材料。

Hightemperature performance of acid lining of the induction crucible furnace mainly depends on the physical and chemical properties and mineral composition of used refractory.
