Definitions

  • the invention relates to a device for transporting sheet metal strip, in particular stainless steel strip, in sagging furnaces of annealing and pickling lines, with at least one driven and possibly cooled transport roller arranged in the sagging furnace, which has a jacket made of a heat-resistant material.
  • the strip is drawn through one or more successive annealing furnaces.
  • the conveyor rollers for the belt are usually arranged outside the furnaces to protect them thermally.
  • driven and water-cooled special steel rollers are also used inside a furnace in order to reduce losses through the furnace openings.
  • the object of the invention is to reduce the belt downtime for changing the transport rollers, a second spare roller installed in the oven being saved.
  • the changing device usually has two roller support beds arranged one behind the other so that the new transport roller can be placed on the changed device before the old roller is removed. This significantly speeds up the changing process.
  • the new transport roller is brought up and brought into such a position that the supporting rollers can again assume their supporting function. Centering the transport roller relative to the support rollers can in a simple manner, for. B. with centering discs or the like.
  • the transport roller can possibly be cooled using a gaseous or liquid medium.
  • the support rollers must be water-cooled.
  • the support rollers can be moved along a guideway with the aid of actuators, the roller ends being guided in scenes.
  • the greatest mutual distance between the support rollers should be greater than the diameter of the transport roller, so that the transport roller can be passed through when changing between the support rollers.
  • the cooling of the support rollers and the transport roller is improved if the chamber is provided with cooling boxes on the inside.
  • the bottom of the chamber can also be cooled and, for this purpose, can be formed by movable, in particular pivotably mounted, insulated or water-cooled base plates.
  • the base plates are swung open so that there is free access to the chamber for the changing device.
  • the changing device preferably has two up and down movable beds for the transport rollers to be replaced.
  • the support rollers with the transport roller must be automatically lowered into the waiting position, the rollers being driven further in order to avoid deformation of the transport roller due to local overheating and damage due to friction between the belt and roller.
  • the sheet metal strip lies on the top of the chamber casing.
  • a sheet metal strip 1 is guided through a sagging furnace 2 and lies on at least one driven transport roller 3.
  • the transport roller 3 usually consists of a hollow core 4, which can be cooled, and a jacket 5 made of heat-resistant material.
  • the transport roller 3 is bearing-free on two driven supported by water-cooled support rollers 6, 7 and is thereby driven indirectly.
  • the support rollers 6, 7 on the one hand and the transport roller on the other hand have centering disks 8 and 9 for axial centering.
  • the support rollers 6, 7 can be moved along a guide path, which is shown in FIG. 2, with actuators (not shown). The ends of the support rollers 6, 7 are guided in scenes 10, which have a circular arc shape in the embodiment shown. With the help of the actuators, the support rollers 6, 7 can be brought into different positions, namely in a working position, which is shown in Fig. 1 with solid lines, further in a waiting position, which is shown in Fig. 1 with dash-dotted lines, and finally in a changing position, which is shown in FIG. 1 again with solid lines and in which the mutual distance of the support rollers 6, 7 is greater than the diameter of the transport roller 3rd
  • the transport roller 3 and the support rollers 6, 7 are accommodated in a chamber 11 which has a passage gap 12 for the transport roller 3 on its upper side.
  • the inside of the chamber 11 is provided with cooling boxes 13 through which cooling water flows in the usual way.
  • the bottom of the chamber 11 is formed by two pivotably mounted and insulated or water-cooled bottom plates 14, 15 on the chamber sides.
  • the pivot bearings 16 of the base plates 14, 15 are arranged so that the pivoted-open base plates 14, 15 shown in broken lines in FIG. 1 allow free access to the chamber 11.
  • a transport path is located below the chamber 11 17 for a changing device 18 with two beds 19 that can be moved up and down for the transport rollers 3 to be replaced.
  • the changing device 18 is first brought into the working position. Then the new transport roller is placed on the outer bed of the changing device with the help of the indoor crane. Then the sheet metal strip 1 is stopped. The support rollers 6, 7 with the transport roller 3 are brought from the working position to the waiting position. The sheet metal strip 1 lies on the upper side of the chamber jacket 20.
  • the base plates 14, 15 are pivoted into the dashed position and the bed 19 of the changing device 18 is raised into the chamber 11 until it grips under the transport roller 3.
  • the support rollers 6, 7 are moved into the lower changing position, in which their mutual distance is greater than the diameter of the transport roller 3.
  • the changing device 18 is automatically moved forwards or backwards by the transport roller 3 lying on the bed 19 out of the chamber 11 to remove.
  • the new transport roller is brought into its assembly position at the same time. The processes described above now take place in the reverse order.
