Corundum block is made with industrial alumina as the main raw material, in which the content of alumina is more than 90%. Corundum block belongs to refractory brick with high alumina content, and it has quite excellent chemical and physical properties.
Abrasion resistance refers to the ability of refractory bricks to resist friction, impact and grinding of hard materials, so the higher is the abrasion resistance, the better is the property of refractory.
The abrasion of corundum block is determined by mineral composition, structure and density of particles, therefore, aggregate quality, material composition and sintering degree of mud will influence the abrasion resistance of corundum block during the production process. Corundum block with raw material of good normal pressure and low porosity has better abrasion resistance.
Sunrise have had tests for abrasion resistance of corundum blocks, the testing method is that: put the surface of corundum block sample which is fixed shape against sandblasting tube, then blow the abrasive media to the surface of sample through sandblasting tube with compressed air, then measure the volume of surface abrasion of corundum block sample.
Corundum block produced by sunrise refractory co., LTD. is in strict accordance with national standards, and the measurement data is real and effective, welcome customers to visit and cooperation.
