Refractory cement is made from high-quality bauxite and high-quality lime , mixed in a certain proportion to form a suitable amount of raw materials.
After sintering, the clinker mainly composed of aluminate is obtained, and then ground it into fine powder to make a water hardening cementitious material with refractory properties.
The fire resistance of refractory cement shall not be lower than 1580 degrees Celsius.
According to different compositions, it can be divided into aluminate refractory cement, low calcium aluminate refractory cement, calcium magnesium aluminate cement, and dolomite refractory cement.
(1) High refractoriness
(2) Good plasticity and bonding strength
(3) Good resistance to slag invasion
(4) Good thermal peelability
