By simulating dynamic erosion tests on AZS33#bricks using ultra white glass liquid and ordinary sodium calcium silicate glass liquid respectively in the laboratory,the erosion amount of fused AZS33# bricks was compared under the same temperature,erosion speed,and erosion time conditions.The analysis showed that due to the low iron content in ultra white glass liquid,the thermal conductivity of the glass liquid was good,and the viscosity of the glass liquid was low.Under the same conditions,the erosion of zirconia corundum bricks was more severe.
