Graphite brick embedded for large-scale blast furnace cooling panel

A graphite brick embedded for a large-scale blast furnace cooling panel adopts a sphenoid graphite brick with rectangular cross section and isosceles trapezoid shaped longitudinal section. The graphite brick is embedded between copper cooling panels, so that the heat of a furnace lining is rapidly transmitted to the cooling panels by virtue of the high thermal conductivity of the graphite brick, thereby reducing the temperature of the hot side of the furnace lining, improving the ability of the furnace lining to bear various erosions in the furnace, avoiding early erosion of the furnace lining, and prolonging the service life of the entire furnace lining.
