Product Description

China Refractory Precast

Prefabricated Shape Refractory

Refractory Precast

Refractory shapes include precast cement and fused or sintered refractory products that are formed prior to installation in furnaces, boilers or other high temperature equipment. Refractories are hard, heat-resistant materials and products such as alumina, silicon carbide, fire clay, bricks, precast shapes, cement or monolithic and ceramic kiln furniture. Ceramics and refractories have high melting points are suitable for applications requiring wear resistance, high temperature strength, electrical or thermal insulation or other specialized characteristics. Some examples of precast refractory shapes include bricks, catalyst supports, checker walls, degassers, furnace liners, nozzles and spargers.

Precast refractory shapes will be a growing specialty in the refractory industry in coming years. with the improved quality that can be achieved through controlled manufacturing processes, their expanding use will play a major role in improving refractory lining performance and reducing maintenance costs across all industries.
