High R.U.L Chrome Corundum fire brick ISO9001 Certificate Kiln refractory material
Chrome corundum Fire brick is made of alumina and chromium oxide according to a certain ratio,molded by high pressure. The use of superior refractory production process made of refractory bricks can improve the inherent quality of products and high temperature performance.
Chrome corundum Refractory brick features:
High refractoriness
High strength
Good wear resistance
Good thermal shock stability
Creep performance at high temperature
Strong anti-erosion characteristics
Chrome corundum Fire brick bricks have achieved good results in metallurgy, glass, steel, carbon black, petrochemical industry.
