Problems solved by technology

[0003] The operating temperature of the aluminum alloy melting furnace is 700-900°C. At 750°C, the viscosity of the aluminum liquid is 0.104Pa·s, which is similar to the viscosity of water (0.1Pa·s) at 20°C. Mg, Zn, Si, Mn, etc. in the alloy are very active elements with strong reducibility, and the alloy Mg and Zn elements have high vapor pressure, which is easier to penetrate into the furnace lining than aluminum liquid, and is compatible with refractory materials

Abstract

The invention discloses a microporous high-penetration-resistance high-aluminum casting material, and a preparation method and an application method thereof. The casting material is prepared from the following components in parts by weight: 51-95 parts of aggregate, 23.5-41.5 parts of powder, 3-6 parts of composite dewetting agent and 0.02-0.4 part of composite water reducing agent, wherein the aggregate is superfine bauxite chamotte; and the powder contains 180-mesh superfine bauxite fine powder, 800-mesh superfine bauxite fine powder, CA-70 cement, alpha-Al2O3 micro powder and SiO2 micro powder. A lining cast by the microporous high-penetration-resistance high-aluminum casting material provided by the invention is low in porosity, small in pore size of air pores and high in resistance to aluminum alloy liquid-state or vapor-state element penetration and corrosion; the aluminum alloy melt penetration resistance is improved; the mechanical strength is high, the high-temperature volume is stable, and the thermal shock resistance is favorable; and nodulation and bulge phenomena at the three-phase juncture can be effectively avoided.

Description

technical field [0001] The invention relates to a microporous high-permeability high-alumina castable, a preparation method and a use method, and belongs to the field of refractory materials. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in national economic construction, and is widely used in various fields such as aviation, aerospace, electric power, machinery manufacturing, and daily life. With the rapid development of science and technology and industrial economy, the demand for aluminum alloy structural materials is increasing day by day. Therefore, the reverberatory furnace, the main equipment of aluminum alloy melting furnace, is constantly being shaped and functionalized. At the same time, more stringent requirements are put forward for the furnace lining material. . [0003] The operating temperature of the aluminum alloy melting furnace is 700-900°C. At 750°C, the viscosity of the aluminum liquid is 0.10...
