Note: If piping temperature is within normal range of MGO, the burner can be switched to MGO without stop the burner.

注：待管路中的油温降低至MGO允许范围内，再将控制面板旋钮切换至MGO，则无需停止燃烧器。

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。
