Acid Erosion Resistance 94.5 SiO2 Silica Refractory Bricks
Introduction:
Good Acid Erosion Resistance Silica Checker Brick 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
Package:
Good Acid Erosion Resistance Silica Checker Brick 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
