High Temperature Resist Refractory Brick Alumina Bricks High Alumina Fire Bricks
Our high alumina bricks are manufactured strictly according to ISO9001 with high quality GL-70 material for rotary kiln which brings advantages of bulk & density more than 3g/cm3, water absorption less than 5%, higher sintering temperature, less Na2O and K2O, etc. The addition of moderate mullite strengthening matrix and the adoption of high temperature bulk effect of some natural minerals realize high softening temperature with load high temperature bending strength and low thermal expansivity.
Performance:
High wearing resistance, corrosion resistance, low creep, stable thermal shock and the service life is 1.5 times of ordinary products.
Applications:
It is mainly used in blast furnace, hot blast stove, baking furnace, carbon calciner, coking furnace, teeming ladle, casting system, boiler, cement kiln, glass furnace and all kinds of kiln linings and thermal equipment. It is applied in metallurgy, machinery, construction, casting, ceramics, electricity, petroleum, chemical industry, etc.
