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%. The sliding plate brick only contains a small amount of resin and asphalt cracked carbon, is high in oxidation resistance and excellent in thermal shock resistance and erosion resistance, and is suitable for smelting of varieties of steel such as low-carbon steel, high-calcium steel and clean steel.
