The above

  The self-flowing corundum castable is made up of three main raw materials :(1) the bauxite aggregate is used for fire resistance and thermal shock stability.(2) corundum material is used to play a wear-resisting role; (3) steel fiber: it is directly combined in the material layer to strengthen the binding force of the material layer, which can greatly improve its toughness, crack resistance, impact resistance, thermal shock resistance and wear resistance, thus extending the service life of castable.
