Abstract

325,307. Herrmann, G., and Zerzog, L. Nov. 26, 1928. Cooling charges; hearths.-A furnace for annealing steel or other castings is provided with a hollow stationary or movable hearth through which, at the termination of the heating operation, air is rapidly blown or sucked to cool the charge d. The hearth is composed of refractory blocks each having a horizontal and a vertical passage, the air entering at a and being directed by the vertical passages b on to the casting d which rests on a metal grating c.
