High alumina castable
Al₂O₃: ≥70
CaO: ≤4
- Commodity name： High alumina castable
Description
Introduction
Using modern technology of the ultrafine powder and low CA cement addition, high alumina castable have improved the middle-temperature strength and high-temperature stability. Low-cement, high alumina castable perform 2-3 times of service life to traditional castable. They have high density, high strength and low abrasion.
