Abstract

The invention provides an a luminum-zirconium-carbon sliding plate brick prepared by combining nickel-aluminum alloy-containing organic silicon resin with high-temperature firing. The aluminum-zirconium-carbon sliding plate brick is prepared from the following raw materials in percentage by weight: 50 to 65 percent of corundum, 15 to 30 percent of fused zirconia corundum, 6 to 12 percent of activated aluminum oxide micropowder, 1 to 3 percent of monoclinic zirconium oxide, 1 to 2 percent of metal silicon micropowder, 1 to 3 percent of carbon black, 1 to 2 percent of carbon-containing resin powder and 0.5 to 1 percent of boron carbide. The aluminum-zirconium-carbon sliding plate brick further comprises organic silicon resin accounting for 3-4% of the total amount of the above raw materials and nickel-aluminum alloy powder accounting for 0.2-1% of the total amount of the above raw materials. According to the invention, a nickel-aluminum alloy raw material is introduced, in-situ fibrous nanocarbon is generated between aggregate and a matrix in a high-temperature firing process under the catalytic action of nickel, the bonding strength and toughness between the aggregate and the matrix are improved, and then the thermal shock resistance and other performance of the material are improved; and the prepared aluminum-zirconium-carbon sliding plate brick has the advantages of long service life, stable performance and the like.

Description

technical field [0001] The invention relates to an aluminum-zirconium-carbon sliding brick made of nickel-aluminum-containing silicone resin combined with high-temperature firing and a production method thereof, belonging to the technical field of refractory materials. Background technique [0002] With the development of steelmaking technology, the capacity of ladles is getting bigger and bigger, and the conditions of steelmaking have become more complex and harsh. At present, the main non-fired and light-fired sliding bricks in the market have been difficult to meet the needs of smelting high-quality steel. At the same time, with the reduction of resources, long-life, high-performance skateboard bricks have become the main development direction of skateboard bricks. Sintered aluminum-carbon and aluminum-zirconium-carbon slide plates are used in large ladle steel flow control systems due to their high strength, good thermal shock resistance, and excellent corrosion resistan...
