Abstract

318,552. Vereinigte Stahlwerke Akt.- Ges., and Schreiber, E. Sept. 5, 1928, [Convention date]. Drawings to Specification. Gases, supplying.-In a gas-fired furnace for annealing metal articles a reducing atmosphere is maintained by supplying additional gas through parts separate from and surrounding the burners. Gas and air are supplied through the burners in the proportion necessary for producing substantially complete combustion.
