High And Middle Grades Refractory Checker Fire Brick For Hot Blast Stove

High And Middle Grades Refractory Checker Fire Brick For Hot Blast Stove

Checker fire brick as a kind of heat regenerator is widely 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. Checker brick is a heat transfer medium to be used in hot blast stove regenerative chamber of blast furnace and usually put in order in the regenerative chamber to play regenerator function on gas period. On air period, checker refractory brick heat cold air to hot air through heat exchange of convection and radiation.

Checker Fire Brick Description

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.

Properties of Checker Fire Brick

.High refractoriness,

.High intensity,

.Large bulk density,

.High refractoriness under load,

.Excellent regenerative capability,

.Great creeping in high temperature.

Introduction of Checker Fire Brick

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.

Characteristics of Checker Fire Brick for Hot Blast Stove

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.

Advantage of Checker Fire Brick

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.
