Product Details
Description Of High Alumina Brick
High alumina brick of over SK35 contain 46% to 80% Alumina content are made from raw materials of high degree of purity of Bauxite and fireclay. For serve under severe conditions, High alumina bricks have excellent mechanical strength, good resistance to thermal spalling, and are highly resistant to chemical attack by vilatile alkaies and some slag. Jucos manufacture and design high alumina bricks to meet the requirements of a great variety of service conditions through quality control.
