Customized Fireclay Checker fire proof brick, Lattice insulating brick for hot blast stove
Fireclay Checker fire proof brick is widely recognized and accepted by the world's iron industry, a
heat exchange capacity, heat storage area, smooth ventilation,
resistance and many other excellent thermal characteristics of the
heat storage body. Lattice brick is a heat transfer medium, mainly
used in the hot stove in the upper part of the regenerator, from
the heat storage effect. In the cold air into the hot air process,
plays an extremely important role.
The hot blast stove is a periodic working device, which has two
working periods: the burning period and the air supply period, and
the two working periods are periodically rotated. During the
burning period, the gaseous fuel is burned in the burner of the hot
air stove to produce high temperature flue gas. The high
temperature flue gas passes through the pores of the hot stove
checker brick, passing the heat to the checker bricks, while the flue gas is heating the lchecker bricks while itself.The temperature drops, the flue gas is cooled
by the checker brick, through the flue pipe from the chimney into the atmosphere.
In the air supply period, from the blower out of the cold wind into
the hot air stove, checker brick heated into hot air, the hot air duct sent to the blast
furnace.
Fireclay Checker fire proof brick Features:
Good volume stability
Low creep property
Low apparent porosity
High density
Strong heat exchange capability
