摘要:

对比了不同CaO含量对镁钙系耐火材料性能的影响。结果发现,随着CaO含量的升高,试样的抗水化性能逐渐下降;当CaO含量不超过20%时试样均具有较好的抗水化性能;当CaO含量达到56.9%时,试样抗水化性能下降明显。

Abstract:

This paper compares the properties of magnesia-dolomite system refractories with different contents of CaO.It is concluded that with the increase of CaO content in samples,the hydration resistance reduces gradually,when the CaO content is below 20%,the samples have good hydration resistance,when the CaO content reaches 56.9%,the hydration resistance drops evidently,and the samples will not be used any more.
