Avantaj și aplicare de cărămizi cu conținut ridicat de alumină

Cărămizile cu conținut ridicat de alumină sunt un material refractar utilizat în mod obișnuit, care este realizat din alumină de înaltă puritate și materiale alumino-silicat.

Avantajele cărămizilor refractare cu conținut ridicat de alumină

1. Good high temperature resistance: cărămizi refractare cu conținut ridicat de alumină can withstand high temperature sintering, so they are widely used in high temperature industrial equipment lining, flue, furnace roof, furnace wall and other parts.
2. Rezistență puternică la coroziune: high alumina refractory bricks have good acid and alkali corrosion resistance, and are suitable for refractory requirements in acidic, alkaline and neutral environments.
3. Rezistență bună la uzură: high alumina fire bricks have good wear resistance and can cope with the wear of high-speed flue gas and solid particles.
4. Strong cold and heat shock resistance: high alumina brick have good cold and heat shock performance, and can withstand sharp temperature changes without breaking.

Application of high alumina fire bricks

High-alumina bricks are often used in metallurgy, chimic, glass and other industries, such as the lining of high-temperature equipment such as blast furnaces, converters, electric furnaces, and glass kilns, as well as the lining of equipment in corrosive environments such as catalyst reactors and pickling pools.
