Divided into three layers:

1. High-strength wear-resisting castable, the main raw materials are :(1) bauxite aggregate, which plays a fire-resistant role;(2) corundum powder plays an wear-resisting role.

Two, lightweight insulation castable, composed of floating beads and bauxite aggregate, to play a role in fire insulation.

Three, aluminum silicate fiberboard, the same as the cyclone separator return material legs
