The high alumina and high strength castable is an unshaped refractory castable made of high alumina clinker as the main raw material, multiple particles and gradings are filled with each other to form a dense structure, and high alumina refractory cement binder, shrinkage inhibitor, dispersant, accelerator and other additives are added. The service temperature is 1300 ºC, with high mechanical strength and good thermal shock resistance and abrasion resistance. After drying and calcining at high temperature, the bulk density will not shrink.
Features
1. Dense bulk density, low porosity, and strong resistance to slag or solution penetration;
2. Good resistance to quenching and heating, thermal shock or thermal shock;
3. High compressive strength and good wear resistance;
4. The construction is convenient, which can be poured into an integral lining or customized castable prefabricated parts for masonry;
5 Resistance to chemical attack.
Application
Aluminum high-strength castable is suitable for various high-temperature kilns and thermal equipment, heating furnace, soaking pit, heat treatment furnace and rotary kiln; Various high-temperature burner linings, water pipe binding linings of heating furnace, components of liquid steel refining unit and high-temperature linings of petrochemical catalytic cracking reactor; Linings such as blast furnace taphole and cupola taphole. It can also be used to make large prefabricated blocks and furnace linings.
