Fire Clay Lattice brick heat storage Yellow checker refractory brick for Hot blast stove
Fire Clay Lattice brick is widely recognized and accepted by the world's steel 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, in the process of exchange cold air into the hot air , plays an extremely important role.
1, High density
2, Low apparent porosity
3, Good volume stability at high temperature.
4, Low creep property, the fireclay checker bricks have excellent thermal characters at high temperature.
5, 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.
