Ceramic alumina tube

     Ceramic alumina tube main chemical composition of Al2O3, depending on the materials become: ceramic tubes, alumina tube, alumina ceramic tubes, alumina protection tube, zirconia ceramic, silicon carbide ceramic, silicon nitride ceramic pipes, tubes and other carbonate .

     Ceramic alumina tube in the heat treatment furnace is used in industrial high-temperature vacuum furnace, vacuum atmosphere furnace, tin bath float glass industry with the pipe, solar glass with protective tube, electric wire support tube, aluminum chloride, chlorine pipe industry, muffle furnace tubes, heat can reach 1150-1800 ℃. As used between the lead rods, lead frame and the metal furnace insulation, fixed and withstand high temperature heating elements; mesh belt furnace heating wire support wire; heating module fixed, insulation and high temperature; thermocouple protection tubes, insulators, etc. .

     Ceramic alumina tube having excellent characteristics: fire-resistant high temperature, high mechanical strength and electrical resistivity. Has good chemical resistance, such as at high operating temperatures can be applied to hydrogen and other reducing atmosphere.

Ceramic alumina tube Features

1, good wear resistance: alumina ceramic wear tube due to the inner liner of corundum ceramics (a-AL2O3), Mohs hardness of up to 9.0 equivalent of HRC90 or more. Therefore, metallurgy, electric power, mining, coal transportation and other industries grinding media have a high abrasion resistance. Confirmed by the industrial operation: its hardened steel wear life is ten times or even several times.

2, corrosion resistance, anti-fouling: As the steel ceramic layer (a-AL2O3), is a neutral character. So with acid and resistance to seawater corrosion, and also has anti-fouling properties.

3, heat resistance and heat rushed Fou performance: As the corundum ceramics (a-AL2O3), a single stable crystal structure. Linear expansion coefficient of 6-8 × 10-6 / 0C, around about 1/2 of the steel pipe.

     95 to 99 porcelain alumina ceramic material has excellent insulating properties, small high-frequency loss, high frequency and good insulation; Noncombustible alumina ceramic, stainless steel, solid difficult to damage, good with other organic materials and metal materials unparalleled properties. Alumina ceramic wear resistance, hardness and corundum the same, reaching nine Mohs hardness, wear resistance and cemented carbide match. Alumina ceramic heat resistance, low coefficient of thermal expansion, high mechanical strength, thermal conductivity and good features, resistant to chemical corrosion and other characteristics of molten metal, products to the leading domestic level.
