產品描述

High-aluminum checker bricks for hot blast stoves are currently widely recognized and accepted by the world’s ironmaking industry as a heat-carrying heat storage body with many superior thermal characteristics, such as strong heat exchange capacity, large heat storage area, smooth ventilation, and low resistance. The high-aluminum checker brick for hot blast stove is a kind of heat transfer medium, which is mainly used in the 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.
