Quick Details
Specifications
Castable refractoriness,also know as refractory,is a kind of granular and powder material which is made of refractory material add some amount of binder.High fluidity,so suitable for the unshaped refractoriness which is formed in the way of pouring.Compared with other unshaped refractory materials,the castable has more binder and moisture content,better fluidity,so the unshaped refractory material is widely used,the materials and binder can be chosen according to the usage conditions.and the castable can not only be directly poured into the lining of the kilns,but also be made into precast block in the way of pouring or vibrating.
Characteristics:
1. High refractoriness, High refractoriness under load.
2. High density, low porosity.
3. Good slag resistance and corrosion resistance.
4. High strength and wear resistance.
5. Good resistance to flake performance.
6. Good thermal shock stability.
7. Scouring resistance
Application:
1. Furnaces of metallurgy industry, heat treatment furnace.
2. Furnace of incineration of garbage, recirculating fluidized bed furnace.
3. Furnaces of chemical industry and construction industry.
