High alumina bricks of over SK35 contain over 45% Alumina and are made from raw materials of unusually high degree of purity of Bauxite and refractory clay. For serve under severe conditions,JUCOS Alumina bricks have excellent mechanical strength, good resistance to thermal spalling, and are highly resistant to chemical attack by vilatile alkaies and some slag. We manufacture and design alumina bricks to meet the requirements of a great variety of service conditions thorough quality control.
Features
Good performance in high temp refractoriness under load
Higher temperate resistant with good refractoriness
Lower impurity content
Good thermal shock resistance performance
Excellent resistance in slag abrasion
Good cold crush strength
