High temperature industrial furnace roof structure

摘要

A refractory hanger brick for high temperature industrial furnace roof construction having an elongated upwardly extending refractory portion having a generally rectangular cross section and a lower refractory base portion having a generally rectangular lower face, each side of the base portion having a base length greater than a corresponding side of the elongated upwardly extending refractory portion so as to provide support for insulating material and/or adjacent filler bricks. The upper end of the elongated upwardly extending refractory portion distal from the lower refractory base portion forms a hanger recess along opposite sides of the upper end. At least one generally laterally extending lug is disposed above each of the hanger recesses to retain the hanger in a fixed position and to provide at least one hanger position along the upper end opposite sides.
