Thermal shock-resistant fire-resistant zirconia-corundum refractory brick
The invention discloses a production method of a novel thermal shock-resistant fire-resistant zirconia-corundum refractory brick. The preparation method comprises following steps: raw materials are prepared, wherein the raw materials include an A particle, a B particle, a C particle, a D particle, an E particle, and an F particle; accessory material brick body moulding is carried out; and drying and sintering are carried out so as to obtain the thermal shock-resistant fire-resistant zirconia-corundum refractory brick. The A particle is used for representing fused cast zirconia corundum particle with a particle size of 1 to 3mm; the B particle is used for representing chromic oxide particle with a particle size of 3 to 4mm; the C particle is used for representing white corundum fine powder with a particle size of 1 to 2mm, the D particle is used for representing chromic oxide fine powder with a particle size of 0.02 to 0.03mm; the E particle is used for representing kyanite powder with a particle size of 0.05 to 0.08mm; and the F particle is used for representing kyanite powder with a particle size of 0.1 to 0.2mm. The thermal shock-resistant fire-resistant zirconia-corundum refractory brick possesses surprising thermal shock resistance, and is excellent in compression resistance.
