Definitions

  • a compression press for reducing the slab width is known, for example, from European Patent 0 112 516 and comprises a pair of pressing tools which are arranged on both broad sides of a slab feed line in such a way that their pressing surfaces point towards one another for pressing a slab.
  • a vibration unit vibrates the pressing tools.
  • This known upsetting press further comprises a width control unit for controlling the position of the pressing tool in the slab width direction and a control which detects that the front end of the slab is arranged between the parallel surfaces of the pressing tools and which then actuates the width control device and, after carrying out a predetermined pressing, the vibration unit .
  • This press is intended to improve the compression effect with regard to the shape and surface of the slab.
  • a device for substantially reducing the width of metallic slabs consisting of a pair of processing tools that work in the plane of the slab and detect the slab on opposite edges.
  • a strong pressing force is generated by a hydraulic drive, which is connected to each of the processing tools, by means of which the width of the slab is reduced.
  • An actuator which is connected to each processing tool, controls their relative distance from one another so that a slab of the desired thickness can be produced.
  • the slab is gripped in a plane perpendicular to the plane of the pressing tools by a punch arranged above and below the slab in order to retain local thickenings of the workpiece, while the width of the slab is reduced by upsetting.
  • the relative distance of the punches from one another and from the slab surface can be changed.
  • the slabs still have temperatures of around 800 ° C and above on their metallic surface in the upsetting press.
  • hold-down devices which are intended to retain local thickening of the slab during the upsetting process, are used continuously working compression press must be permanently on the surface of the slab and exposed to high temperatures there, which is why they must be cooled.
  • Untargeted water cooling of the hold-down devices cannot be used because the thickening of the slab at the side means that the cooling water cannot run off when it is compressed at the side; an evaporating water surface forms on the slab surface, which leads to strong uncontrolled local cooling.
  • Different local cooling of the slab not only has a negative impact on the slab compression process in the upsetting press, but also has an increasingly negative effect in the subsequent horizontal stands for reducing the thickness of the rolling stock.
  • the object of the invention is to protect the conveying devices or hold-down devices for the red-hot slab, which come into permanent contact with the hot slab surface, in particular in the case of a continuously operating upsetting press, against the effects of the high temperatures as a result of direct heat transfer or heat radiation, and to locally cool the slab during to avoid the upsetting process.
  • the invention is characterized in that coolant channels are arranged in a known manner in each holder roll, with axially extending inlet and outlet channels and with a plurality of peripheral peripheral channels in the peripheral region of the holding roller, essentially parallel to the rolling surfaces of the holding roller as well as with connecting channels between inlet and outlet channels and horizontal channels and that at least the retaining roller can be connected from an inner hub part provided with bearing pins and an outer one to the hub part there is hollow cylindrical roller, and that the hub part on the outside or the roller inside has circumferential annular grooves, from which the connecting channels to the horizontal channels or to the inlet channels or outlet channels.
  • the heat is preferably carried away from the roll surface by the coolant flow and the selected arrangement of all the cooling channels requires a uniform flow of coolant through all the inner parts of the roll, so that these are also cooled uniformly. If, due to the choice of material, for design reasons or for reasons of strength, the holding roller should be made in several parts, the solution proposed here nevertheless ensures the internal cooling of the rollers.
  • the bearing housing of the holding roller in particular its bearing cover facing the slab surface, is additionally provided with internal cooling in the form of a cooling pocket. It is also useful if the coolant supply of the holding roller is connected to the coolant supply for its bearing housing and bearing cover with cool bags.
  • the upset press is a flying upset press for reducing the width of slabs in a hot wide strip roughing mill, the slabs being almost continuously produced by a slab casting system upstream of the upset press be fed.
  • the upsetting press has horizontal scaffolding stands; is a crankcase that starts cranking adjustable in the scaffold stand. The crankcase is adjusted using a mechanical adjustment. Pressing tools are arranged on both sides of the slab; the pressing tool has a crank drive which acts perpendicular to the slab and a feed drive which acts in the tangential direction, that is to say parallel to the slab. The movement sequences of the crank drive and feed drive are synchronized in accordance with the feed movement of the slab.
  • the pressing tool is adjusted in rapid succession to the speed of the slab, touches (without relative movement to the slab) perpendicular to the slab edge, compresses the slab sideways and is then moved back laterally at a distance from the slab.
  • Figure 1 shows that the upsetting press in the area between the pressing tools above and below the slab 1 has height-adjustable holding rollers 2, that in the inlet area 3 and in the outlet area 4 of the upsetting press driving rollers 5 are arranged above and below the slab, and that holding rollers 2 and driving rollers 5 are provided with internal cooling, which is shown in more detail in FIGS. 2 and 3.
  • the two holding rollers 2 are arranged approximately in the middle of the slab width and viewed in the slab feed direction 6 one behind the other and are held in a holding frame 7 and vertical guides 8 so as to be vertically displaceable.
  • the holding frame 7 and the adjusting device 9 for the height shifting of the holding rollers are connected to a crossbar 10, which in each case rests firmly on the upper or lower spars 11, 11 'of the horizontal stand of the upsetting press.
  • the driver rollers 5 are held in a swivel arm 12, the pivot pins of which are arranged on a vertical crossbar 13.
  • the vertical crossbeam is on the Upper spars 11 and on the lower spars 11 'of the scaffold stand and screwed laterally outside the infeed roller table 14 and the outfeed roller table 15 for the slab 1.
  • the lower driving roller 5 can be driven and in the outfeed area of the upsetting press both are upper and lower driver roller can be driven.
  • FIG. 2 shows a holding roller 2, which consists of an inner hub part 17 provided with a bearing pin 16 and an outer hollow cylindrical roller 18 which can be connected to the hub part, the hub part on the outside or the roller on the inside having circumferential annular grooves 19, of which connecting channels 20 the horizontal channels 21 or to the inlet channels 22 or outlet channels 23.
  • the inlet and outlet channels run axially.
  • a plurality of the horizontal channels 21 are arranged peripherally evenly distributed in the circumferential area of the rollers and essentially parallel to their running surfaces 24.
  • the bearing housing of the holding roller in particular its bearing cover 25 pointing to the slab surface, is additionally provided with internal cooling, which in the present case is shaped into an elongated cooling pocket 26. The connections for the coolant are not shown in detail.
  • the coolant flows through the cooling channels in the direction of the arrows shown.
  • the cooling device for the holding roller and the cooling device for its bearing housing or bearing cover are connected to one another by pipes, which are not shown in detail, but can correspond to conventional pipeline construction. It can be seen that the arrangement of the coolant channels in this way ensures optimal internal cooling of the holding rollers, in particular the rolling surfaces of the holding rollers in contact with the high-temperature slab surface.
  • FIG. 3 shows the formation of the coolant channels in the driven driver roller 5, the inlet and outlet channels 22, 23 being designed as a spaced double tube 27 opposite the drive side and running in the middle of the axis, the inner tube 28 being the inlet channel and the outer tube 29 is the outlet channel, which is connected to the horizontal channels 21 via the connecting channels 20.
  • the bearing caps 25 are provided with internal cooling, which is shaped as a cooling pocket 26.
  • the coolant is supplied with the coolant via the Coolant connection 30, from which a pipe connection to the bearing cap 25 goes off.
  • the object on which the invention is based is achieved in full by avoiding the slab from deflecting or bulging during a continuous width reduction and preventing uncontrolled local cooling of the slab, which would always occur if instead of that According to the invention provided internal cooling of the holding rollers and the driver rollers, an open water cooling would be carried out
