Abstract

433,918. Electric furnaces. HERAEUS - VACUUMSCHMELZE AKT.- GES., Postfach 91, Hanau-on-Main, Germany. Dec. 15, 1934, No. 36054. Convention date, April 30. [Class 39 (iii)] [See also Group XII] In an electric furnace for annealing metal strip in a protective atmosphere comprising a vertical chamber C traversed by the strip K in ascending and descending paths, the upper end of the chamber is fitted with a removable cover D carrying a holder H in which are mounted the heating elements J and the strip-supporting roller G. The cover D is formed with a depending flange engaging in an annular oil seal E.
