High alumina refractory mortar joint material fire clay slurry good plasticity
The main material of high-aluminum refractory mortar is high-alumina clinker, and the binder is made of soft clay or chemical binder. The Al2O3 content is determined according to the brick composition and use requirements of the masonry.
It can be widely used in various industrial furnaces for high alumina brick masonry.
It is used for laying furnace roof, regenerator, combustion chamber, etc. in hot blast stove; blast furnace bottom, hearth, belly, furnace waist, etc. And repairing industrial furnace roof, furnace wall and other parts.
Characteristic of high alumina refractory mortar:
1. Good plasticity and convenient construction;
2. Strong bonding strength and corrosion resistance;
3. High refractoriness;
4. Good resistance to slag invasion;
5. Good thermal spalling.
