| Abstract: | MgOspinelCr2O3 castable was developed with magnesia, white fused alumina, bauxite and spinel as main raw materials, and the influence of Cr2O3 on physical properties, slag resistance and thermal shock resistance of the MgOspinel castable was investigated. The castable was applied for slag line of 90t RH refining ladle, the average service life was up to 96.5 heats without any repairs. |
| Keywords: | MgOspinelCr2O3 Ladle Slag line Castable Development and application |
