Application fields of lightweight refractory materials：
High-temperature furnace body and lining: Due to its good thermal insulation and heat insulation performance, lightweight refractory materials are often used in high-temperature furnace body, furnace and lining. For example, steel smelting furnace, ceramic kiln, cement kiln, etc.
Thermal insulation materials: used for external thermal insulation and heat insulation of industrial equipment, such as thermal insulation layer of thermal equipment, pipeline insulation, etc., which can effectively save energy and avoid the influence of external temperature on equipment.
Thermal power plant and nuclear power plant: lightweight refractory materials are used for boiler linings, heat exchangers in thermal power plants, and thermal insulation barriers and firewalls in nuclear power plants.
Aerospace and spacecraft: In the field of aerospace, lightweight refractory materials are often used as outer shell materials of spacecraft, especially as thermal insulation protective layers when entering the atmosphere.
Chemical industry: used for thermal insulation of chemical reactors, heating furnaces, steam generators and other equipment, especially in high temperature and highly corrosive environments.
Construction industry: as a building insulation material, it is used for the insulation layer of building walls or pipelines in high temperature environments to provide thermal isolation and reduce energy consumption.
Main types of lightweight refractory materials:
Lightweight clay bricks: Made of clay and an appropriate amount of foaming agent or expansion material (such as expanded perlite). It has good thermal insulation and fire resistance, and is suitable for the insulation layer of high-temperature furnaces and kilns.
Expanded perlite: Made of expanded perlite particles, it has very light weight and good thermal insulation, and is widely used in industrial insulation and heat preservation.
Lightweight bauxite bricks: Made of raw materials such as bauxite, it is often used in high-temperature industries and has good compressive strength and fire resistance.
Aluminum silicate fiber products: Made of aluminum silicate fiber materials, it is lightweight and high-temperature resistant, and is suitable for insulation and heat preservation layers in high-temperature environments.
Lightweight high-aluminum bricks:
It has a high aluminum content and high refractoriness, and is often used in the insulation layer of high-temperature furnaces.
