摘　　要：天然白云石资源丰富,遍布各地,它是镁钙质耐火材料的优质原料。镁钙质耐火材料能净化钢水,具有做钢包衬不粘渣、在水泥窑里能粘牢窑皮及容易水化等特殊性能。随着对钢质量要求的提高,大型水泥窑的发展,镁钙质耐火材料前景广阔,但水化问题还没有得到彻底解决。Natural dolomite resources are abundant and distributed through out the country,making it a high-quality raw material for magnesium-calcium refractories.Magnesium-calcium refractories have the ability to purify liquid steel,are used as the ladle lining without sticking slags,can firmly adhere to the kiln coating in cement kilns,and exhibit easy hydration and other unique properties.With the improvement of steel quality requirements and the development of large-scale cement kilns,magnesium-calcium refractories have broad prospects.However,the hydration problem has not been completely resolved yet.
