Refractory Brick

Refractory 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 dry pressing, the adobe need to pushed in the drying kiln  to stoving or stay in the air  to drying. This progress will need about 3-5 days.  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.
