General Information
Silica brick is 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 clinker and brown fused alumina as base materials and adding high quality SiC fines and high purity flake graphite. It has the advantages of excellent slag resistance, thermal shock resistance, good resistance to mechanical erosion, abrasion resistance, etc.
Features
1.High purity
2.Long service life
3.Accurate size tolerance
4.Pure color
5. Luster appearance
6..Good thermal conductivity
7.Good creep resistance
Application of the refractory silica bricks
Silica brick is mainly used for Coke oven, glass kiln, hot-blast stove, tunnel kiln,Acidic furnace non-ferrous metal smelting and some other thermotechnical equipment in good furnace building materials.
