Abstract

124,125. Griffin, P. J. June 17, 1918. Furnace details.-A furnace roof comprises an expansion ring situated between the central body portion and an outer abutment ring. As shown in connexion with a removable circular roof for an electric furnace, the outer ring of skew-back bricks 12 is secured by angle-irons 20. 21 in an outer metal ring 10. The expansion portion of the roof is formed by two rings of bricks 13, 14 which are shouldered to fit corresponding recesses in the skew-backs, and in the bricks of the outer of the two rings. Between the abutting faces at 26, 27, 28, destructible spacing pieces of wood or the like are placed, and when these burn away room is left for expansion. The central portion of the roof consists of rings of blocks 15, 16, 17, and a keyblock 18, which are formed to provide a flat upper surface, and openings 19 for the electrodes.
