High Strength and Wear Resistant Castable

High-strength wear-resistant heat-insulating castable is an amorphous refractory material with high-aluminum aggregate with an AL2O3 content greater than 75% as the particle raw material, combined with ultrafine powder, binder, and additives, and has the characteristics of high wear resistance and good thermal shock resistance.

High-strength wear-resistant heat-insulating castable is a refractory castable made of high-aluminum raw materials as aggregates and powders in the traditional ratio and added with binders. On the basis of preparing high-strength wear-resistant heat-insulating castable, the particle grading is adjusted, different admixtures are added, the amount of cement is reduced, the performance is improved, the medium-temperature strength and load softening temperature are increased, the thermal conductivity is reduced, and the thermal stability is good. The furnace body has strong integrity, the airtightness is better than that of brick-built furnace walls, the furnace life is extended, the furnace repair cost is saved, and the economic benefits are significant.
