Definitions

  • annealing material which can be used with both rectangular as well as round cross-section occurs are used as walking beam and pacemaker furnaces, as transporting the annealing material with less damage than ensure, for example, pusher furnaces by which Annealing material is pushed through.
  • German patent application 43 43 675 describes a walking beam furnace, on the respective cooled walking beam and / or fixed beams short fasteners for Support bars running at an angle to the transport direction flat supports for the annealing material are arranged. With With the help of web bolts, these webs can be attached to their End bores or eyelets in one be fixed at the same angle to the longitudinal axis.
  • a major disadvantage of the walking beam furnaces described above is that their requirements are only are designed for round or flat material.
  • the invention is based on the problem a walking beam furnace for heating round and of creating flat material.
  • the solution to this problem is a walking beam furnace according to claim 1, on the walking beam and fixed beam different Support bars for round or flat material are arranged.
  • the flat goods supporting webs have one in the feed direction wider middle part with a flat surface and each one narrower in the feed direction and sloping slope behind the middle section.
  • the round goods support webs are trough-shaped; they are preferably narrow in the middle horizontal surface and two rising to the right and left of it Slants on.
  • the width of the round goods support bars in the feed direction, the width of the beveled Parts of the flat goods support webs correspond.
  • the slopes the round goods and the slopes of the flat goods supporting webs are matched to each other in such a way that View of a wavy surface of the supporting webs results in the lower lying troughs with Alternate higher areas.
  • the hollows serve here to the round annealing material against shifting in to secure its transport position.
  • Flat annealed material, for example slabs, on the other hand can over the troughs lie on the outstanding, flat surfaces.
  • the slopes of the supporting bars also point in Direction of transport seen falling to the right or left Surfaces on. Step on the round-goods supporting bars this moves on; in the case of the flat goods supporting bars, however with every slope right and left.
  • the sloping surfaces reduce the build-up of scale on the supporting bars.
  • the lifting and fixed beams can be on their surface have a longitudinal web. This is from the U-shaped foot of the supporting webs.
  • the Flat goods supporting webs that have a hole on the side, are attached to the longitudinal web with the help of bolts.
  • the Round goods support bars are placed on the longitudinal bar and by positive locking between two flat goods supporting webs fixed positively in their position and thus secured against loosening. This makes it easy Exchanging the round goods carrier bars allows.
  • Walking beam and fixed beam 1 consist of a cooled Support tube 2 with flat goods support bars 3 and round goods support bars 4.
  • the supporting bars 3 and 4 are in alternating Order arranged on the support tube 2.
  • the flat goods supporting webs 3 have a flat contact surface 5 and one each in the feed direction in front and bevel behind it 6.
  • the round goods supporting webs 4 are characterized by a - seen from the side - Narrow, horizontal surface in the middle 7 from, in front of and behind in the feed direction lying slopes 8 rise.
  • the flat pads 5 serve as a support surface for flat Warm material, while from slopes 6, 8 and horizontal surface 7 existing troughs of the recording serve from round heating material.
  • the flat goods supporting webs 3 there is one in the middle Hole 9 for receiving one of the attachment to the support tube 2 serving bolt 13, against by a stopper 14 Falling out of the bolt 13 is closed.
  • the bolt 13 connects the flat goods support web 3 with one on one Longitudinal web 10 welded cams 15, which also has a hole in the middle.
  • the round goods supporting webs 4 are only on the longitudinal web 10 of the support tube 2 attached, by positive locking held between two flat goods supporting webs 3 and secured at the same time against lifting off.
  • Fig. 3 can be seen that the flat support 5 of the Flat goods support web 3 is wider in the feed direction as its bevels 6 and the round goods-supporting webs 4. The serves to ensure the necessary contact area for the flat annealing material.
  • the bevels 6 are seen on the right in the feed direction and bevelled again on the left.
  • the slopes 8 the round goods supporting webs 4 have such a bevel 12 only offset. This arrangement reduces scale build-up on the supporting bars. It also causes the arrangement of the cushions and the change of the side sloping slopes a constant change of Supporting the annealing material and thus its uniformity Heat.
