Dry anti-seepage refractories works well with simple construction, good thermal insulation effect and strong anti-permeability. The working principle of Dry anti-seepage refractory material is to react alkali ions in materials and metal liquids at high temperature, form isolation layer on the surface, prevent sodium salt from going to cathode block.

The high-strength alkali-resistant refractory castable has good resistance to alkaline gas and slag, and has a long service life. High strength alkali resistant castable is mainly used for lining of other industrial furnaces such as kiln door cover, decomposition furnace, preheater system and pipeline system.
Castables for ladle working layer is made from high purity corundum, magnesium aluminate spinel and fused MgO as main aggregates, superfine powder bonding technology and appropriate additives.
Magnesia mortar for fire bricks is made from high-quality magnesite, magnesia mortar performs well in use with excellent workability, desirable hardening time, high adhesive strength, and good corrosion resistance under high temperature.
