Clay Fired Refractory Checker/Chequer Brick is made from clinker clay by mixing, forming, drying, sintering and matching characterized by good resistance to corrosion and abrasion, good thermal shock resistance, good spelling resistance, high mechanical strength, good volume stability under high temperature.


The Clay Fired Refractory Checker/ Chequer Brick can be divided into three process: Raw material, molding, burning.Generally, refractory brick was molded by dry pressing. By means of mixing the material uniformity in proportion and aging mixture some time. Then, pour some powders into the module and dry pressing.

After this progress, then push the adobe into the tunnel furnace or shuttle kiln to burning around 1300C. This progress will be need about 5-7 days.
After burning, the brick will be packed in pallet and leave the factory.
