Abstract: The math model for erosion-corrosion of liquid steel-inclusion two-phase flow in tundish on refractory has been established and the numerical calculation to erosion-corrosion characteristics of refractory in tundish with turbulence inhibitor, dams and weirs is carried out. Calculated results show that the position with max erosion-corrosion rate in tundish is at turbulence inhibitor, next is the tundish wall near slag line in pouring-in area and the side wall of dams and weirs facing to liquid steel flow, the erosion-corrosion of refractory in another region is very small and can be ignored.

摘要： 建立了中间包内钢液-夹杂物两相流对耐火材料冲蚀的数学模型,并对设置有湍流控制器、挡渣堰、挡渣坝中间包耐火材料的冲蚀特性进行了数值模拟计算。计算结果表明,中间包内冲蚀率最大的位置在湍流控制器内,其次是注入区近渣线处包壁、挡渣堰与挡渣坝迎向钢液流动一侧壁面,其他区域耐火材料的冲蚀很小,可以忽略不计。
