400C High Thermal High quality manufacturer fused magnesia alumina spinel for refractory fireproof brick is made of local top grade fireclay materials under the high temperature according to the lasted
national standard, which possesses even bulk density, high strength, low thermal conductivity and low impurity.
400C High Thermal High quality manufacturer fused magnesia alumina spinel for refractory fireproof 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, 400C High Thermal High quality manufacturer fused magnesia alumina spinel for refractory fireproof brick will be packed in pallet and leave the factory.
