Refractory Castable

Kerui Refractory mainly produces and supplies high-temperature products such as refractory castables. The construction method of castables does not affect the shape and size. After the castable material solidifies, it forms a high-hardness refractory lining. Customers are advised to choose the appropriate castables for construction based on different types of characteristics.

10+ Types of Kerui Refractory Castable for Sale

Kerui Refractory mainly offers 12 types of high temperature castable refractory products and various customized castables based on different compositions.

Introduction of Kerui Monolithic Castable Refractory Material

The castable refractory composition consists of refractory cement (binder material), refractory aggregates, and binders. Castable refractories have characteristics such as high temperature resistance, high density, high strength, good flowability, chemical corrosion resistance, and easy installation. Common construction methods include casting, spraying, pumping, and so on.

Refractory aggregates are the main component of castable refractories. They mainly include various materials such as clay, high alumina, silica, and so on.

Refractory cement serves as the binder and powder material in castable refractories. It plays an important role in the bonding of refractory cement. The particle size of aggregates has a certain impact on the flowability of refractory cement.

Kerui High Temp Castable Refractory Properties

Easy to Construct

Kerui pourable refractory has good flowability, fast curing time, and good plasticity. During construction, the castable is mixed with a certain amount of water before being applied. Its flexibility makes it suitable for use in construction sites of different sizes and shapes. Additionally, its quick-drying effect significantly reduces construction time costs.

Chemical Corrosion Resistance

Refractory castables have good corrosion resistance to acidic, alkaline, and neutral media. When exposed to corrosive chemical environments, the monolithic refractory products can maintain the integrity of the structure and the stability of its performance without being affected. This is crucial for stability and durability in applications.

High Temperature Resistance

Kerui castables typically have a refractoriness between 1300-1800 degrees Celsius. They exhibit excellent high-temperature resistance. This feature is able to withstand extreme temperatures and heat changes in high-temperature furnaces without structural changes. Therefore, they are suitable for maintaining durability in high-temperature working environments.

High Strength

Refractory castables are composed of high-performance refractory aggregates and binders. After proper mixing, they have high density, low porosity, and high strength. They exhibit excellent wear resistance. Additionally, under high pressure and torsional forces, castables do not crack or deform. This is crucial for their ability to withstand mechanical stresses in high-temperature environments.

Wide Uses of Kerui Refractory Casting Castable

Refractories castables, refractory coatings, and refractory prefabricated components have extensive applications in many industries. They are commonly used for lining high-temperature equipment such as furnace linings, furnace doors, chimneys, furnace covers, outlet pipes, wear repair areas, and insulation layers. Additionally, they are widely used in the construction of refractory structures and road construction.

  • In the steel and metallurgy industry, they are used in blast furnaces, hot blast stoves, heating furnaces, metallurgical furnaces, hearths, and so on.
  • In non-ferrous metal smelting, they are used in non-ferrous metal smelting furnaces, electric furnaces, heating furnaces, electrolytic cells, oxidation converters, electric arc furnaces, and so on.
  • In the building materials and industrial manufacturing industry, they are used in atmosphere kilns, vacuum furnaces, ceramic kilns, cement kilns, lime kilns, calcination kilns, rotary kilns, and so on.
  • In power plants, they are used in boilers, waste incinerators, high-temperature reactors, cracking furnaces, and so on.
  • In other industries, they are used in cremators, heat treatment furnaces, road construction and repair, buildings, nitric acid condensation towers, and so on.
