Characteristics and Development Trend of Refractory Castables

As an important building material, refractory castable has the characteristics of high-temperature resistance, wear resistance, and chemical corrosion resistance, and is widely used in metallurgy, chemical industry, electric power and construction, and other fields. This article will introduce the definition, characteristics, and application of refractory castables in different fields.

1. Definition and characteristics of refractory castables

Refractory castable is a building material with high-temperature durability prepared based on refractory materials through appropriate formulas and processes. Its main features include:

High-temperature resistance: refractory castables can maintain stable physical and chemical properties in high-temperature environments, and are not easily affected by thermal expansion, melting, or burning.

Wear resistance: Due to the high hardness and wear resistance of refractory castables, they can effectively resist mechanical wear and friction and prolong the service life of the equipment.

Chemical corrosion resistance: Refractory castables are not easily corroded by acids, alkalis, salts, and other chemical substances, and can maintain stable performance in corrosive media.

2. Application fields of refractory castables

Metallurgical industry: In metallurgical furnaces, converters, electric furnaces, and other high-temperature equipment, refractory castables are widely used as lining materials to protect equipment from high temperature and chemical substances.

Chemical industry: Refractory castables are used in the lining of chemical reactors, storage tanks, pipelines, and other equipment, which can resist the corrosion of chemical substances and ensure the safe operation of equipment.

Electric power industry: In the boilers, chimneys, and combustion equipment of thermal power plants, refractory castables are used for lining and protective layers, which can withstand the impact of high temperature and flue gas and prolong the life of the equipment.

Construction industry: Refractory castables are used in firewalls, insulation, and fire-resistant structures of buildings to provide effective fire protection and durability.
