Abstract

493,028. Annealing furnaces. ROCHLING'SCHE EISENUND STAHLWERKE GES. April 19, 1938, No. 11712. Convention date, April 20, 1937. [Class 51 (ii)] In a bright-annealing furnace for metal strip a, which is drawn through an annealing chamber d and a cooling chamber (not shown), and is protected by a gas heavier than air, e.g. blast-furnace gas, fed through a pipe g, the strip a passes into, and out of, the bottom of the furnace through gas-collecting chambers i, provided with a baffle k, to ensure exclusion of air.
