摘　　要：镁钙质耐火材料具有净化钢液、耐火度高、抗热震性好以及在碱性渣中的抗腐蚀性能高等优点,被广泛用于钢铁冶炼行业。然而镁钙质耐火材料在制造、储存和使用过程中会发生MgO和CaO的水化,严重制约了镁钙质耐火材料的应用与发展。综述了镁钙质耐火材料的特点及其水化机制,从烧结致密法、表面处理法及密封包装法三个方面总结了目前镁钙质耐火材料抗水化的研究现状及存在的问题,同时也展望了镁钙质耐火材料抗水化技术的发展方向与研究重点。Magnesia-calcia refractories are widely used in the iron and steel smelting industry because of their advantages of steel liquid purification,high refractoriness,good thermal shock resistance and high corrosion resistance in basic slag.However,MgO and CaO usually hydrate in the process of manufacturing,storage and use of magnesia-calcia refractories,which seriously restricts the application and the development of magnesia-calcia refractories.In this work,the characteristics and hydration mechanism of magnesia-calcia refractories were reviewed,and the current research status and existing problems of the anti-hydration of magnesia-calcia refractories were summarized from three aspects:sintering densification,surface treatment and sealed packaging.In addition,the development trends and the research emphases of anti-hydration technology of magnesia-calcia refractories in the future were also prospected.
