Developemnt and Application of Al2O3—MgO Castable for Large Ladles in Con—casting System

摘要

Using Al2O3-MgO castable in large ladle can avoid containation of molten steel from carbon-containing refractories and increas ladle servic life remarkably,The addition of magnesia and fine powder,the effect of grain size on the proper-ties of the castable,especially linear change and structure spalling have been studied,Castable pro-dued for large ladle with small weare rate has got good applicatio result.
