Specifications

1.Passed ISO 9001;
2.57% Alumina content,or as customized;
3. Carborundum Fire Brick is widely used in iron-making.

AL2O3SiCC carborundum fire brick are universal materials for the lining of molten pretreatment equipments of molten iron tank, torpedo car, etc. The products are shaped by machine power by using dense bauxite clinkerand brown fused alumina as base materials and adding high quality SiC fines and high purity glake fraphite. It has the advantages of excellent slag resistance, thermal shock resistance, good resistance to mechanical erosion, abrasion resistance, etc.

Carborundum products belong to high grade refractory material,maximal use temperature is 1500°C,it has excellent thermal conductivity,heat shock stability,high load softening point and very good wear-resisting property,widely used in various industries with special requirement.
