Refractory Castables for Sale
Kerui refractory castables are made of refractory aggregate, refractory powder, binder, and other additives, and can be used directly or by adding the appropriate amount of water or other liquids. Once cast or gunned into place, the castable material hardens and cures to form a solid and durable refractory lining. Refractory castables can be installed using different methods depending on the specific application and equipment. Such as casting, gunning, troweling, and pumping.

Advantage of Refractory Castables
The lightweight aggregates and particles in the refractory castables reduce heat transfer and provide excellent thermal insulation properties that reduce heat loss and improve energy efficiency in furnaces and other heat treatment equipment. Welcome to inquire at Kerui, we will provide you with the best quality products with reasonable price.
Refractory castables are usually made with high-performance binding agents and fine-grained aggregates that are properly mixed and cured to form a high-strength structure. This high strength allows the refractory castables to withstand mechanical and thermal stresses at high temperatures, maintaining the structural stability and integrity of the furnace.
Castables are suitable for different equipment shapes and size requirements. They can be customized to specific shapes and configurations, they can be quickly poured, sprayed, or smoothed to meet the needs of a wide range of equipment and processes, and they are easy to construct. Welcome to visit Kerui factory, we will provide you with the best service.
Fire-resistant castables can be made with aggregates and binders that have good resistance to chemical attacks. These materials are resistant to corrosive media such as molten metals, acid and alkali solutions, and corrosive gases. They protect equipment from erosion by acids and bases, corrosive gases, and molten metals. Welcome to Inquiry.
