High Alumina Refractory Castable


Refractory cement, also known as aluminate cement, is a hydraulic cementitious material made from bauxite and limestone, which is calcined to produce a clinker with calcium aluminate as the main component and an alumina content of about 50%, and then ground. The refractoriness is not less than 1580℃, and it is usually yellow or brown, and sometimes gray. According to the composition, it can be divided into aluminate refractory cement, low-calcium aluminate refractory cement, calcium-magnesium aluminate cement and dolomite refractory cement.

Product detail

High Alumina Refractory Castable

Product Parameters

High Alumina Refractory Castable is a high-performance unshaped refractory material manufactured by our factory using selected bauxite aggregate, alumina powder, and optimized binders. It is designed for furnace and kiln lining applications that require higher refractoriness, better slag resistance, and longer service life compared with standard alumina castables.
With stable quality and factory direct supply, this castable is widely used in cement, steel, power, and petrochemical industries.

Key Features:
• High Refractoriness – Suitable for medium and high-temperature furnace & kiln lining
• High Mechanical Strength – Excellent resistance to abrasion and load
• Good Thermal Shock Resistance – Stable performance during temperature fluctuations
• Strong Chemical Resistance – Good resistance to slag, gas, and alkali attack
• Easy Installation – Good flowability and workability on site
