Application fields of high alumina high strength refractory castables

Application fields of high alumina high strength refractory castables

High-aluminum high-strength refractory castables have been widely used in many industrial fields due to their excellent refractory properties, high strength and good corrosion resistance. The following are its main application areas:

Steel industry:

In the process of steel smelting, high-aluminum and high-strength refractory castables are widely used in key parts such as blast furnaces, converters, and electric furnaces. It can effectively resist the erosion of high-temperature molten metal, maintain the integrity of the furnace lining and extend its service life. It can also be used for refractory linings in furnaces, hearths, furnace roofs, furnace doors, and other parts, such as heating furnaces, melting furnaces, and other equipment.

Nonferrous metal industry:

In the process of nonferrous metal smelting and processing, high-aluminum high-strength refractory castables are used to construct furnace linings to ensure the high-temperature stability and safety of the furnace body. For example, aluminum smelting furnaces, copper smelting furnaces, etc. all require the use of this material. It is also suitable for the refractory lining of aluminum electrolytic cells, copper smelting furnaces, nickel furnaces and other equipment.

Ceramic industry:

During the ceramic firing process, high-aluminum high-strength refractory castables are used to construct kiln linings, which can withstand high temperatures and atmosphere erosion, ensuring the quality and output of ceramic products. It is also suitable for various high-temperature burner linings, as well as heating furnace water pipe wrapping linings and other parts.

Petrochemical industry:

High-aluminum and high-strength refractory castables are used in the refractory lining of cracking furnaces, hydroconverters, catalytic cracking units and other equipment to meet the use requirements of these equipment in high temperature, high pressure and corrosive environments.

Building materials industry:

Used for refractory lining of cement rotary kilns, glass kilns and other kilns. For example, high-alumina refractory castables can be used in the kiln door cover, grate cooler, preheater, decomposition furnace, tertiary air duct and other parts of cement rotary kilns.

Power industry:

It can be used for refractory lining of boilers in coal-fired, gas-fired, biomass-fired power plants. It is also used for the selection of different parts of linings of power station boilers, melting furnaces, soaking furnaces, heat treatment furnaces and induction furnaces.

Waste incineration industry:

Used for refractory lining of waste incinerators to improve the fire resistance of incinerators.

In addition, high-aluminum and high-strength refractory castables are also widely used for lining protection of some mechanical parts or equipment with high temperature, wear resistance and corrosion resistance requirements.
