High alumina brick can be divided into ordinary high alumina brick and low creep high alumina brick two categories.
1, ordinary high aluminum bricks are divided into: LZ-48, LZ-55, LZ-65, LZ-70, LZ-80, LZ-55G, LZ-65G, LZ-75G nine grades. In the grade, L and Z are the first letters of the Chinese Pinyin of aluminum and brick, the number is the quality fraction of alumina, and the subsequent G represents the brick for blast furnace.
Secondary G4 high alumina firebrick
2, low creep high aluminum brick refers to a high aluminum product with low creep rate at high temperature. According to the physical and chemical indexes, the brand can be divided into: DRL-155,DRL-150,DRL-145,DRL-140,DRL-135,DRL-130,DRL-127, seven brands. The number is one-tenth of the creep rate test temperature, and D, R and L in the grade are the initial letters of the Chinese pinyin for low, creep and aluminum respectively. The dimensions can be produced according to the drawings provided by the customer.
3, the quality of high aluminum brick determines the service life of the kiln, Zhuangcheng refractory material suggested that the blast furnace in the selection of high aluminum refractory brick manufacturers cooperation, must review the qualification, choose a factory with production area.
