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.
