Refractory cement is a refractory material used as a binder and refractory powder when making refractory castables. It uses high-quality bauxite and lime as raw materials, and is mixed into an appropriate amount of raw material in a certain proportion. After sintering, the resulting product is aluminate Clinker, which is the main component, is then ground into fine powder to make a fire-resistant hydraulic cementitious material called refractory cement.
Refractory cement is also called aluminate cement. Aluminate cement is made by calcining bauxite and limestone into clinker with calcium aluminate as the main component and an alumina content of about 50%, and then grinding it. Hydraulic cementitious materials. The color of aluminate cement is usually yellow or brown, but also gray.
Refractory cement is divided into aluminate cement, dolomite cement, calcium magnesium aluminate cement, etc. according to different compositions. Refractory cement can also be used as a binding agent or refractory powder when making refractory castables.
