1. Main characters: Its specific surface area is large, has good regenerating ability and can save energy significantly, increase the temperature of hot air; can save working hours because of simply masonry; solves the bond problem of Visco. Balls.
2. Applications: Low creep high alumina brick for hot blast furnace is used in regenerator, combustion chamber, and hot blast pipe for hot blast furnace. Particularly it used in the wall that bearing heavy and that can prolong its working life as well as saving cost of operation for hot blast furnace.
