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:
During the steel smelting process, high-aluminum 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 tops, furnace doors and other parts, such as heating furnaces, melting furnaces and other equipment.
*Non-ferrous metal industry:
During the smelting and processing of non-ferrous metals, 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 need to use this material.
It is also suitable for refractory linings 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 temperature and atmosphere erosion, and ensure 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.
*Glass industry:
During the glass melting process, high-aluminum high-strength refractory castables are used to construct the bottom and wall of the glass melting furnace. It can withstand the erosion and scouring of high-temperature molten glass, and maintain the continuity and stability of glass production.
*Petrochemical industry:
High-aluminum high-strength refractory castables are used for refractory linings of equipment such as cracking furnaces, hydrogenation converters, catalytic cracking units, etc., to meet the use requirements of these equipment in high temperature, high pressure and corrosive environments.
*Building materials industry:
For refractory linings of cement rotary kilns, glass kilns and other kilns. For example, high-aluminum 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.
*Electric power industry:
It can be applied to the refractory lining of boilers in coal-fired, gas-fired, biomass-fired power plants.
It is also used for the selection of different parts of the lining of power station boilers, casting furnaces, soaking furnaces, heat treatment furnaces and induction furnaces.
*Waste incineration industry:
It is used for the refractory lining of waste incinerators to improve the refractory performance of the incinerator.
In addition, high-aluminum and high-strength refractory castables are also widely used for the lining protection of some mechanical parts or equipment with high temperature, wear resistance and erosion resistance requirements.
High-aluminum and high-strength refractory castables play an important role in many industrial fields. Their excellent refractory performance, high strength and good erosion resistance make them an indispensable key material in these fields.
