Andalusite Refractory Castable
Andalusite refractory castable consists of aggregate, powder, and additives. Aggregate consists of high alumina clinker and andalusite, accounting for 60 to 70% of the total amount of aggregate and powder; The powder consists of andalusite powder,α-Al2O3 powder, corundum powder, silica micopowder, spherical clay powder, and calcium aluminate cement, the total amount of which accounts for 30-40% of the sum of aggregate and powder.
Andalusite Refractory Castable Features
The andalusite refractory castable has the advantages of low impurity content, excellent high-temperature performance, and wide application range.After burning, the compressive strength, high-temperature bending strength, load softening temperature, and creep resistance are all excellent.
