Low Cement Refractory 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 Low Cement Refractory Castable. Compared with common Refractory Castable, Low Cement Refractory Castable owns the below

 

characteristics: 

1. The dosage of cement is low, the content of calcium only accounts for 1/4-1/3 of common Refractory Castable2. Wter consumption rate during the construction is almost 1/2 or 1/3 of the common Refractory Castable, so the Low Cement Refractory Castable has high density and low porosity.3. High normal temperature cure property, intensity will be increased after medium temperature and high temperature. Three or five times more than common Refractory Castable.4. Good volume stability under high temperature.

Application:

Material for metallurgy, petroleum, chemical and other industries kilnsPart of refining installation, like ladle coverInsert for roof of the kiln
