Definitions

  • Document US-A-2652 037 relates to sup ⁇ ports of the heating body (radiant tubes) in the form of a double pin supported by a simple support fixed in a tube perpendicular to the radiant tube.
  • the expansion of the radiant tube causes a sliding on the supports which is the cause of wear, micro-welds, etc.
  • the tubes in which the supports are fixed are bulky and prevent the continuous passage of a steel strip which goes around radiant tubes arranged in staggered rows.
  • a similar torque can also be generated by parasitic voltages created during the execution of the welds of the tubular elements and of the curves which would be released during the first firing of the heating body and / or after a repair.
  • the present invention aims to provide a solution to these problems by providing a device for supporting the heating body for annealing ovens allowing the free expansion of the heating body and completely eliminating the risk of creep of the free end without influencing cer unfavorably its heating capacity or the proper functioning of the oven characterized in that it comprises a connecting rod connecting together the two outer hairpin curves of the heating body and a support of the upper pin sliding on a rigidly fixed tubular support arm in the wall of the oven allowing displa ⁇ cements in the sliding direction of this support.
  • the round shape of the support and the support allows the automatic centering of the heating body and the significant play of these parts between them allows very easy placement.
  • the connecting rod connecting the two "hairpin" curves of the heating body allows relative movement of the tube elements between them and holds the lower pin to the upper pin by suspension. The sliding point which supported the upper pin on the lower pin is eliminated.
  • the heating body is supported by a support welded to its upper part and sliding on a support arm rigidly fixed in the wall of the oven.
  • the support is advantageously chosen so as to allow movement in the direction of the support arm so that the heating body is not subjected to strong stresses.
  • the support arm is advantageously tubular, is closed at its inner end by a welded pad and is preferably stuffed with a thermal insulating material or the like.
  • FIG. 2 shows a support according to the invention.
  • FIG. 2 the support 7 of the heating body 1 which is provided in the case of FIG. 1, is replaced by a connecting rod 17.
  • the support 18 advantageously slides on a 0 support arm 19, preferably made of stainless steel
  • the support arm can be equipped with a gauge 26 consisting for example of a 25 x 5 mm square dish which indicates the behavior of this support, inside the oven from the outside of the latter.
