        Depending upon the concasting condition, we provide ladle shrouds of Alumina Graphite or Alumina Zirconia Graphite. The products have the following characteristics.
        1) Prebaking unnecessary
        With the functional gradient structure, our ladle shrouds are characterized by high thermal shock resistance and can be applied to the con-casting process directly from the ambient temperature, without preheating.
        2) Long service life
        Specially designed slag line composition for customer casting conditions guarantee our ladle shrouds with the properties of high erosion resistance.
