Refractory materials are used for high-temperature industrial linings and thermal protection in steel plants, furnaces, ladles, tundishes and related metallurgical equipment.
Refractory Materials
This page currently uses refractory bricks as the representative product for the refractory materials category. Refractory bricks are shaped refractory products used in furnace and steelmaking lining positions where heat resistance, thermal stability, wear resistance and slag or chemical resistance may be required.
Technical Specification
Below is a reference presentation for common refractory brick directions. Final specification should be confirmed according to application position, working temperature, slag condition, chemical atmosphere, lining design and service life target.
Refractory Brick Reference Specification
| Product Type | Main Material Direction | Typical Service Temperature | Common Application |
|---|---|---|---|
| Fireclay Brick | Alumina silicate / fireclay | Approx. 1300-1700°C depending on grade | General furnace lining and backup lining |
| High Alumina Brick | High alumina / mullite direction | Approx. 1500-1790°C depending on Al2O3 content | Steelmaking furnace, ladle, kiln and high-temperature lining |
| Insulating Fire Brick | Lightweight alumina silicate direction | Approx. 1100-1500°C depending on grade | Backup insulation and energy-saving lining |
| Customized Refractory Brick | Magnesia, carbon, SiC or other special direction | According to working condition | Ladle, tundish, furnace, coke oven and special metallurgical service |
Representative Product Expression
- Refractory Brick: shaped refractory material used for furnace, kiln, ladle, tundish, coke oven and other high-temperature industrial lining positions.
- Fireclay brick and high alumina brick can be discussed for common heat-resistant lining requirements where strength, thermal stability and cost control are important.
- Insulating fire brick can be used for backup lining and thermal insulation positions where lower heat loss and lighter lining weight are required.
- Future additions under this category may include ladle refractories, tundish refractories, continuous casting refractories, castables and repair materials.
Recommended Applications
- Steel plant furnace and metallurgical equipment lining.
- Ladle, tundish, reheating furnace and heat treatment furnace applications.
- Coke oven, kiln and other high-temperature industrial positions.
- Maintenance, repair and refractory replacement projects.
Product Features
- High-temperature resistance and practical lining protection.
- Different material grades can be selected for working temperature and chemical condition.
- Supports shaped refractory brick supply and future refractory product expansion.
- Suitable for category-page use before detailed SKU pages are added.
