Refractory Castables – High Performance Monolithic Refractory Solutions
What is Refractory Castable?
Refractory Castable (also known as Castable Refractory Cement or Monolithic Refractory) is a ready-mix powder of high-grade refractory materials such as alumina, silica, calcium aluminate, and binders.
When mixed with water, it forms a durable and heat-resistant material used to line furnaces, kilns, incinerators, and boilers.
Unlike traditional firebricks, refractory castables can be poured, troweled, or gunned into place, allowing seamless, joint-free linings that offer superior insulation, strength, and longevity under high-temperature conditions.
Key Features of Refractory Castables
- High Temperature Resistance (up to 1800°C)
- Excellent Thermal Shock & Abrasion Resistance
- Strong Chemical and Corrosion Resistance
- Low Thermal Conductivity for energy efficiency
- Ease of Installation – pourable or gunning type application
- High Mechanical Strength and volume stability
- Customizable Formulations as per furnace type and working condition
Types of Refractory Castables
At Mitticool Refractories, we manufacture and supply a complete range of castable refractory materials designed to perform in various industrial environments.
| Type | Description | Applications |
| Conventional Castables | Alumina content 30–45%, cost-effective and reliable | Boilers, kilns, and general furnaces |
| Low Cement Castables (LCC) | High density, low porosity, improved strength | Steel ladles, cement rotary kilns |
| Ultra-Low Cement Castables (ULCC) | Higher refractoriness and corrosion resistance | Non-ferrous furnaces, petrochemical units |
| No-Cement Castables | Pure alumina/silica bonding, very high purity | Hydrogen or carbon-sensitive furnaces |
| Insulating Castables | Lightweight and high insulation value | Backup linings and thermal barriers |
| Plastic & Gunning Castables | Ready to use and easy to apply | Spot repairs, patching, and quick relining |
