This parameter table mainly displays precast refractory shapes made from silicon carbide casting material. We support precasts made from various refractory materials, such as high alumina casting material.
High-quality and Precise Production Refractory Precast
Ronghua refractory precast block provides a solution for the high-temperature industry that does not require on-site casting during construction. We offer high-quality precast refractory.
- Raw Materials: Ronghua Refractory uses high-quality casting materials to produce refractory precast blocks, including corundum silicon castable, high alumina silicon carbide castable, high alumina castable, low cement castable, steel fiber wear-resistant castable, anti-seepage castable, and so on. These castables can all be made into high-performance refractory precast.
- Production Process: We have high-quality and precise production equipment. We support custom-made prefabricated blocks for specific areas. Carefully designed molds ensure that the casting dimensions and shapes meet the needs of our partners.
- High-Temperature Firing: The refractory precast blocks we produce support high-temperature firing. The firing temperature reaches to 1680 degrees Celsius.
- Suitable parts: These refractory precasts can be used in areas such as abrasion, erosion, thermal shock, metal penetration, and so on.
- Functions: Internal support, external connections, and so on.
