High alumina castable description:
High alumina castable adopts submircon technology. Micro powder is used as binder, aluminate cement as coagulation accelerator, some antidetotant and water reducer will also be added in during the production of High alumina castable , compared with common castable.
High alumina castable adopts submircon powder technology. Micro powder is used as anchoring agent, aluminate cement as coagulation accelerator, some antidetonant and water reducer will also be added in during the production of High alumina castable . Compared with common Refractory Castable, High alumina castable owns the below characteristics:
Our major products are as follows:
1) Refractory brick.
2) Castable series.

High alumina castable advantage:
1. cement is more lower, the content of CaO will be only 1/4-1/3 of common refractory castable. 2. Water consumption rate during the construction is almost 1/2 or 1/3 of the common refractory castable, with high density and low porosity. 3. Good volume stabilit under high tempetature. 4. High normal temp cure property, intensity will be increased after medium tempetature and high tempeature. three or five times more than common refractory castable.
