Tabular Aluminacan be used as the main component in aluminium-carbon, aluminium-magnesium-carbon, magnesia-aluminium-carbon, magnesia-spinel and aluminium-chromium refractory bricks. It can also be introduced into high aluminium amorphous refractories as the enriched alumina component. It can be widely used in steel, casting, ceramics and other industries, and its application in iron and steel industry almost covers. The whole process of ironmaking and steelmaking has been completed. Packaging is divided into two kinds: one is ton bag packaging, the other is 25 kg woven bag small packaging, you can also choose according to user needs.
