Refractory castables for thermoelectric, chemical and other industries< /span>

  With high-alumina bauxite and corundum as main raw materials, high-alumina cement, pure calcium aluminate cement, ultrafine powder and inorganic salts like as phosphoric acid, phosphate and aluminum sulfate as binding agents, it has the advantages of high strength and great erosion and wear resistance performance, and is suitable for boilers for thermoelectric and chemical industries and easily washed parts, which can effectively extend the service life of thermal kilns.

  Heat insulation castable is lightweight castable, with clay or high-alumina lightweight aggregate, and ceramsite as raw materials, and high-alumina cement and ultrafine powder as binding agent. It features great anti-erosion and anti-wear performance and high heat insulation. It can be used for heat insulation of all thermal equipment, or used as heat insulation and wear-resistant lining.

 High-strength, wear-resistant castable, the physical and chemical indicators are shown in the following table: span>
