Description of Low Reheating Linear Rate High Alumina Standard Brick LZ75 Widely Used For hot blast stove
High alumina is a general name of Low Reheating Linear Rate High Alumina Standard Brick LZ75 Widely Used For hot blast stove, which is made of bauxide, andalusite, corundum, mullite other refractory raw materials.
Application of Low Reheating Linear Rate High Alumina Standard Brick LZ75 Widely Used For hot blast stove
Low Reheating Linear Rate High Alumina Standard Brick LZ75 Widely Used For hot blast stove is widely used in high thermal kilns and stoves, like hot blast stove, blast furnace, rotary kiln, lime kiln, reheating stove.
Low Reheating Linear Rate High Alumina Standard Brick LZ75 Widely Used For hot blast stove 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.
