doi:10.3969/j.issn.1001-1935.2024.06.013

Abstract

Abstract: Basic refractory materials are commonly used as linings in metallurgical equipment.However,the harsh working environment often leads to significant damage to these refractories,reducing their high-temperature service performance.The slag penetration and the dissolution of refractory materials caused by the corrosion of the molten slag to basic refractory materials are the main causes of the damage.This paper briefly summarized the test methods of slag corrosion resistance of basic refractories and their advantages and disadvantages,reviewed the research progress of the slag corrosion resistance mechanism of magnesia refractories,magnesia-chrome refractories,magnesium-aluminate spinel refractories,and magnesia-calcia refractories,and discussed their future development directions.

Key words: molten slag, basic refractories, corrosion mechanism, penetration, dissolution

摘要： 碱性耐火材料常被用于冶金设备的内衬。然而,由于工作环境严苛,耐火材料易损毁,使其高温服役性能降低。熔渣对碱性耐火材料侵蚀引起的熔渣渗透和耐火材料溶解是导致其损毁的主要原因。简要概述了碱性耐火材料抗渣侵蚀试验方法及其优缺点,综述了镁质耐火材料、镁铬质耐火材料、镁铝尖晶石质耐火材料及镁钙质耐火材料抗渣侵蚀机制的研究进展,并展望了该领域未来的发展方向。
