Checker brick is widely recognized and accepted by the world iron making industry at present, a kind of heat storage body with strong heat exchange ability, large heat storage area, smooth ventilation, low resistance and many other excellent types of lattice brick. Lattice bricks are a kind of heat transfer medium, used in the regenerator of blast furnace hot blast furnace, usually orderly arranged in the regenerator, in the "furnace period" to play the role of heat storage, in the "air supply period" by convection heat exchange and radiation heat exchange, heating the cold air into hot air.
At present,checker bricks are mainly used in blast furnace hot blast furnace and flame furnace. The checker bricks are mainly used in the regenerator of hot blast stove. The checker bricks with lattice holes are arranged in an orderly manner. The upper and lower holes of the checker bricks can allow gas to pass through
