19 holes Yellow Fire Clay Checker Bricks customized refractory brick for hot blast stove
Fireclay Checker refractory brick manufactured by us takes high grade clay clinker as main raw materia, special shaped with holes that has many good thermal characteristics. It is widely recognized and accepted by the world's steel industry as a heat exchange body. As a heat transfer medium, the bricks are mainly used in the hot stove in the upper part of the regenerator, in the process of exchange cold air into the hot air , plays an extremely important role.
Fireclay Checker refractory brick Features:
1, Low apparent porosity
2, Good volume stability at high temperature.
3, Low creep property, the fireclay checker bricks have excellent thermal characters at high temperature.
4, Strong heat exchange capability, 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.
