Definitions

  • the invention relates to a device for replacing tapping troughs in shaft furnaces.
  • Pig iron and slag are tapped from a blast furnace at regular intervals. Depending on the amount of pig iron produced, there are eight to twelve taps within 24 hours. During the tapping process, pig iron and slag are separated from one another in a so-called main tapping channel. Such main tapping channels on large blast furnaces have recently been carried out with large cross sections. The main tapping trough is usually followed by other tapping troughs and tipping troughs for pig iron (until they are handed over to pans or torpedo cars) and slag. While the slag is being removed from the main tapping channel, the pig iron remains in this channel between tapping.
  • blast furnaces that have only one tap hole.
  • Such blast furnaces must be throttled for the time of repair or relining of the fireproof tapping lining, or the blast furnace must be shut down for long periods of work.
  • Also known is a device for changing the main tapping channel of a blast furnace (DE patent application P 36 24 266.7), in which at least four lifting elements are arranged in a stationary or non-stationary manner in front of the tapping hole of the blast furnace on the hut floor, which act on trusses on which the main tapping channel rests, the channel to be replaced can be lowered onto a means of transport located on the hut floor, in particular rail-bound, and the newly delivered channel can be raised from the means of transport to the level of the casting platform, and that the main tapping channel with the crossbeams is pneumatically actuated by means of the steel structure of the casting platform Holding arms is held.
  • the object of the invention is to provide a replacement device for tapping troughs in shaft furnaces, the installation of which does not require expensive earthwork and foundation work and which can also be erected subsequently in existing metallurgical plants.
  • a replacement device should be designed so that it is also portable, so that only one device for replacing tapping troughs has to be purchased in a metallurgical plant with several furnaces, especially since the times of use of the changing device can be easily coordinated.
  • Tapping troughs on shaft furnaces have a high weight, for example more than 100 t including the refractory lining.
  • the required lifting height from the hut floor to the racking platform is over 4 m. Raising and lowering the tapping trough for repair purposes places considerable demands on the traction mechanism.
  • the tapping channel (4) is located on the transport means (1) which can be moved on rails in the hut hallway (2). Traverses (10), which are arranged under the tapping channel (4), can be seen between the tapping channel and the transport platform. Stranded ropes or climbing bars (6) of the tension elements (5) are attached to the crossbeams (10).
  • the tension elements (5) are arranged on support beams (7) welded to the tapping platform (3) of the shaft furnace.
  • the tension elements are supplied by a hydraulic pump unit (not shown here).
  • FIG. 2 shows, in contrast to FIG. 1, tension elements (5) which are arranged on the crossbeams (10) of the tapping channel (4).
  • the device works in reverse, i.e. the traction elements (5) are pulled up or down with the tapping channel (4) to the tapping platform (3).
  • a known strand or rod conveying system in which loads are moved with the aid of electrohydraulically driven lifters, is suitable for the replacement device according to the invention.
  • FIG. 3 and 4 show an embodiment in which the tension elements (5) and the hydraulic pump unit (8) are arranged on a transportable platform (9).
  • the hydraulic hoses for connecting the pump unit and tension elements have not been shown.
  • This platform can be made in one or more parts and stands with its feet on the gutter support beams (7) of the racking platform (3).
  • the tapping channel (4) is detachably attached to the rods or strands (6) of the tension elements (5) by means of a shackle connection (12), which is only indicated.
  • the tapping channel (4) is raised to the level of the tapping platform (3), the tapping channel (4) is supported with the aid of retractable and retractable supports (11) arranged laterally under the tapping platform.
  • the supports (11) are pushed through corresponding openings in the channel support supports (7).
  • the platform (9) with the pulling elements (5) can be removed by a crane.
  • hydraulic pump unit (8) can also be set up (not shown), for example on the side of the tapping platform (3), in which case hose connections to the traction elements (5) must exist.
  • Fig. 5 shows a tapping channel (4) hanging on rods or stranded ropes (6).
  • the tension elements (5) are mounted here on the platform of a slewing ring (13) which runs on rails which are located on the platform (9).
  • the slewing ring (13) can be moved through 360 ° in the horizontal.
  • Fig. 6 is to show that it is possible with the help of the slewing ring (13), the tapping channel (4) hanging on the tension elements (5), deviating from the position assumed on the tapping platform (3), during the lowering to a different angular position bring.
  • the rails for the means of transport are e.g. arranged at right angles to the position of the gutter from the tapping platform.
