Checker Brick is a kind of heat transfer medium, which is mainly used for middle upper part of regenerative chamber in hot blast stove for thermal storage in the burning period. checker firebrick plays the extremely important function in the process of heating cool wind up to hot wind through convective heat exchange and radiation heat transfer in the blast period. checker fire block is widely used in iron smelting industry as a kind of heat carrier with excellent thermal engineering performance of strong heat exchange ability, large thermal storage area, smooth ventilation and low resistance. checker refractory block is mainly used in the hot blast stove.
Checker fire bricks are a heat transfer medium, play a role in the burning furnace heat storage period, in the air is by convection heat exchange and radiation heat exchange, the cold air is heated into the hot wind. which is used in hot blast furnace heat storage room, usually arranged in an orderly manner in the storage room.
checker bricks with transparent hole and a plurality of side surfaces parallel to each other, and checker refractory bricks is located in the two parallel on the surface of the positioning bulge and the positioning groove. checker fire blocks have good volume stability and high load creep performance is excellent, high density and low porosity.
Checker fire blocks have strong heat exchange capacity, large thermal storage area, smooth ventilation and low resistance. checker blocks are a kind of heat transfer medium bricks. checker blocks is applied in heat storage chamber of blast furnace and hot blast stove.
|Checker Fire Brick|

|Refractoriness Under Load (0.2MPa)||℃||≥1500||≥1400|
|Permanent Linear Change (1500℃*2h)||%||±0.2||±0.2|
Check fire brick is mainly used in regenerative chamber of hot blast stove. Put checker brick with certain structure and holes in order and the gas can pass through up and down holes. also checker brick is used in Iron and Steel Industry for saving energy with many excellent thermal characteristics such as strong heat exchange, large heat storage area, smooth ventilation, low resistance and etc.
