Introduction:
sizes and shapes for Silica Refractory Bricks are made with raw material high grade bauxite and SiC and special sintering process. Silica-mullite bricks are characterized by high density, good performance of abrasion resistance and thermal shock resistance. sizes and shapes for Silica Refractory Bricks can constantly form protective layer for reducing accrection formation, long application cycle,etc.
sizes and shapes for Silica Refractory Bricks Generally suitable for thermal surface refractory lining or other refractory back lining insulation layer. Refractory lining or thermal insulation for industrial furnaces in petroleum or chemical industries, such as ethylene cracking furnaces, tubular furnaces, reforming furnaces for synthetic ammonia, gas generators and high temperature shuttle kilns.
Tunnel kiln, push board kiln, roller kiln, wood kiln refractory lining material for industrial and household ceramics
sizes and shapes for Silica Refractory Bricks is made of silicon as raw material with high temp firing ,which silicon oxide is above 93% ,used in hot blast furnace,coke oven,glass kiln,these brick have good volume stability at high temperature, high refractoriness under the load,small rate of shrinkage in working condition.
Package:
sizes and shapes for Silica Refractory Bricks are packed on wooden pallet and then polyethylene film is placed over it,finally the package is tied up with steel strips or as your request
Good Acid Erosion Resistance Silica Checker Brick:
