Refractory Checker Brick Description Checker bricks are widely recognized and accepted by the world's ironmaking industry as a heat transfer and heat storage body with many superior thermal properties such as strong heat exchange capacity, large heat storage area, smooth ventilation, and low resistance. Checker bricks are a heat transfer medium, mainly used in the upper and middle parts of the heat storage chamber of the hot blast furnace to store heat. In the process of heating cold air into hot air, it plays an extremely important role.
We can provide various types of refractory checker bricks according to customer needs and kiln conditions, such as silica checker bricks, clay checker bricks, high alumina checker bricks, mullite checker bricks, sillimanite checker bricks, etc.
