High aluminum checker brick for hot blast stove
The high-aluminum checker brick for hot blast stove is a kind of heat-carrying heat storage body with many excellent thermal characteristics such as strong heat exchange capacity, large heat storage area, smooth ventilation, and low resistance, which is widely recognized and accepted by the ironmaking industry. Checker brick is a kind of heat transfer medium, which is mainly used in the upper middle and upper part of the regenerator of hot blast stove to store heat. In the process of heating cold air into hot air, it plays an extremely important role.
High alumina bricks for hot blast stoves are made of high alumina bauxite clinker mixed with partially bonded clay. Among them, according to different parts of use, a series of bricks of different sizes with Al2O3 content greater than 48% are provided to pursue the efficiency and convenience of hot blast stove construction, as well as the stability and long life of subsequent maintenance and use.
