Research progress on slag resistance of different basic refractories
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-tem-perature 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 pa-per briefly summarized the test methods of slag corrosion resistance of basic refractories and their advan-tages and disadvantages,reviewed the research progress of the slag corrosion resistance mechanism of magnesia refractories,magnesia-chrome refractories,magnesium-aluminate spinel refractories,and mag-nesia-calcia refractories,and discussed their future development directions.
