摘　　要：感应电渣离心浇铸H13钢斜轧辊毛坯中夹杂物分布均匀 ,最大直径不大于 7μm ,大部分小于2 μm。铸件毛坯的二次枝晶间距仅为 40 0 μm ,晶粒度为 9～ 10级。结果表明 ,感应电渣离心浇铸H13钢毛坯制造的斜轧辊 。The inclusions in the blank of steel H13 for slanting roller produced by centrifugal induction electroslag casting (CIESC) is dispersed uniformly in blank, most of which the diameters are less than 2 μm and maximum diameter of inclusion is 7 μm. The second dendrite space in the blank casting is 400 μm with grain size 9～10. The application results show that the service life of slanting roller made of CIESC steel H13 blank is up to that made of ESR forged steel H13 blank.
