Abstract
401,584. Metalheating furnaces. RUSS, E. F., 37, Kaiser- Friedrich Ufer, Cologne, Germany. April 11, 1933, No. 10781. [Class 51 (ii).] In a continuous furnace for heating metal strip, wire, or the like, of the kind in which the strip hangs in a curve between the conveying-rollers 3, 4, the lower part of the curve is supported by rollers 6, 7 covered with refractory material and disposed near the middle of the furnace at a level considerably lower than that of the rollers 3, 4. The latter and the closure plates 12, 13 at the ends of the furnace are adjustable vertically, either together or independently. The rollers 6, 7, which are driven at the same peripheral speed as the rollers 3, 4, are removable through side openings normally covered by plates 26, 27, and are vertically adjustable by hand-wheels 10, 11 so that the position of the strip with relation to the heating means can be controlled. The furnace is heated by transverse electric resistance elements 30 which are removable, either singly or in groups. As shown in Fig. 2, each element 30 can be removed laterally, after detachment of the casing 26<1> and the connection 27<1>, through an aperture in the furnace wall closed by a removable plug 28. Figs. 3 and 4 show a modification in which the rollers 3, 4 are mounted in end chambers 20, 21 having downwardly-extending lips 22, 23 and adjustable vertically on the end plates 24, 25. To permit free expansion and contraction of the latter, the holes through which extend the securing bolts 33, Fig. 7, are enlarged or elongated and spring washers 36 are fitted.
