High-temperature sintered magnesium-zirconium sliding plate brick added with titanium reinforced corundum and production method of high-temperature sintered magnesium-zirconium sliding plate brick

The invention relates to a high-temperature sintered magnesium-zirconium sliding plate brick added with titanium-reinforced corundum and a production method thereof, and the high-temperature sintered magnesium-zirconium sliding plate brick comprises the following raw materials: 58-69.5% of sintered magnesia, 10-15% of macrocrystalline fused magnesia, 5-15% of titanium-reinforced corundum, 5-10% of fused alumina zirconia, 0.5-1% of silica fume, 2-3% of metal silicon, 1-2% of metal silicon micropowder and 1-2% of magnesium-aluminum alloy. The weight of the thermosetting phenolic resin binding agent is 3-5% of the total weight of the raw materials. The apparent porosity of the product is 5-8%, the volume density is 3.00-3.10 g/cm < 3 >, the normal-temperature compressive strength is 120-180 MPa, the normal-temperature breaking strength is 15-35 MPa, the high-temperature breaking strength is 15-18 MPa, and the residual breaking strength retention rate (1100 DEG C water cooling for 3 times) is 62-73%.
