Castable is also called  refractory castable.It is a kind of granular and powdered materials made of refractorymaterials by adding a certain amount of binder, with high liquidity, the casting molding of unshaped refractory materials.

     Compared with other unshaped refractory material, binder and high moisture content, good fluidity, therefore the application range of castable is wide, can be used according to the condition of material used and bonded to choose. Can be directly poured into the lining of the body, and by pouring or vibrating method made of prefabricated chunks.

Aggregate type:Clay aggregate (Al2O3 30% ~ 45%)
                                    High alumina aggregate (Al2O3%26ge; 45%)

                                    Siliceous aggregate (SiO2%26ge; 85%, Al2O3%26lt; 10%)

                                   Alkaline aggregate (with magnesite, dolomite etc.)

                                    A special aggregate (carbon, carbides, nitrides, zircon, spinel, etc.)

                                  Insulation aggregate (with perlite, vermiculite, ceramsite, cenosphere, light                                                  brick sand,cement clinker, porousalumina hollow ball etc.)

Advantages:

1.Thermal rock resistance

2.High strength

3.Wear, erosion resistance

5.Good plasticity

6.ISO 9001:2008
