Definitions

  • the invention relates to a casting wheel with an exchangeable, driven casting ring for a two-roll belt casting machine, in which the casting ring is supported by an additional support and bearing element and on the inside in each case by a support and joining roller rotatably mounted with a roll core.
  • Such a casting wheel is known from DE-PS 642 642.
  • the drive takes place via the support and joining roller, which is connected in a rotationally fixed manner to the roller core driven by a roller drive.
  • the roller core absorbs part of the weight of the casting wheel.
  • the performance of a two-roll belt casting machine depends, among other things, on the diameter of the casting wheel. Casting 5 mm thick and 1,000 mm wide strips results in a casting rate of 2 to / min. for example a casting wheel diameter of approximately 2,000 mm. For a greater casting performance of 3 to / min. casting wheels with a diameter of up to 3,000 mm are required. Casting wheels of this size cannot be economically manufactured and used in the designs previously implemented.
  • the object of the invention is to provide a casting wheel with a casting ring which can be replaced quickly and easily for a two-roll belt casting machine.
  • roller core is fixed and that the casting ring is supported on the inside on a plurality of support and bearing elements, the support and joining roller and the support and bearing elements being rotatably mounted in the roller core.
  • the casting ring can be replaced quickly. To replace it, it is only necessary to loosen the support and bearing elements on the inside of the casting ring. The casting ring can then be removed from the roll core and replaced with a new casting ring.
  • the casting ring can be axially fixed on the roll core in various ways.
  • the casting ring has on its inside a running channel in which the support and joining roller and / or at least one support and bearing element engage.
  • the support and bearing elements are preferably rollers. However, they can also be designed as hydraulic cushions.
  • actuating elements supported on the roller core in particular tensioning and adjusting cylinder piston units, are provided.
  • the roller core in a cooling chamber that can be filled with coolant is arranged on both ends through with the casting ring moving side windows is completed, which are sealed at their periphery with sealing lips against the casting ring delimiting the cooling chamber.
  • the two-roll band casting machine shown in FIGS. 1 and 2 consists of two similar casting wheels 1, 2 arranged horizontally next to one another, which form a preferably adjustable casting gap 3, the width of which is equal to the thickness of a strip 4 to be cast.
  • Molten metal is poured from a casting vessel 5 above the casting gap 3 between the two rollers 1, 2. So that the molten metal does not flow off to the side, stationary sealing elements 6, 7 are provided on both sides.
  • Each casting roller 1, 2 has a fixed core 8 with, for example, three support rollers 9, 10, 11 and a support and Joining roller 12. While the support rollers 9-11 are freely rotatable, the support and joining roller 12 is rotatably mounted and driven. On the support rollers 9-11 and the support and joining roller 12, a casting ring 13 runs.
  • the casting ring 13 on the one hand and connected side plates 14, 15 connected thereto form a cooling chamber for a coolant, in particular cooling water, which is introduced into the cooling chamber via an inlet 16 and is discharged via an outlet 17.
  • the cooling water first flows around the upper half of the support and joining roller 12, then flows along the back of the casting ring to the first support roller 11, flows around it and then continues along the casting wheel 13 and the other support rollers 9, 10 until it reaches Support and joining roller 12 arrives, on the lower half of which it flows along to the outlet 17.
  • the fixed core 8 here constructed in a welded steel construction, contains two lateral bearing plates 29, 30, which are connected to fixed hollow bearing shafts 18, 19, which in turn are held in bearing pieces, not shown.
  • a bearing shaft 20 is held in the plates 29, 30, on which the support and joining roller 12 is rotatably mounted.
  • the support and joining roller 12 carries on one end face a gearwheel 21 which is in engagement with a driven gearwheel 22 which is rotatably mounted in the plate 30.
  • the support roller 10 and preferably also the support roller 9 or / and 11 are each freely rotatably supported on a bearing shaft 23 which is supported by blocks 24a, 24b and a bridge member 24c in a radially adjustable manner by a cylinder piston unit 25.
  • the cylinder-piston unit 25 is held in a bridge member 26 between the plates 29,30.
  • the casting ring 13 has on its inside a trough 13a, in which the support and joining roller 12 and the support rollers 9-11 engage positively and in this way fix the casting ring 13 radially and axially.
  • the front side disks 14, 15 are freely rotatably supported on the hollow bearing shafts 18, 19. They are sealed on their inner circumference by means of lip seals 14a, 15a against the hollow bearing shafts 18, 19 and on their outer circumference by means of crimp seals 14b, 15b against ring collars 13b, 13c of the casting wheel 13.
  • the side disks 14, 15 are taken along by the rotating casting ring 13 via these pinch seals 14b, 15b.
  • the cooling space sealed to the outside by the side disks 14, 15 and the casting ring 13 and the seals 14a, 15a, 14b, 15b is opposite the bearings of the support rollers 9-11 and the bearings and the drive of the support and joining roller 12 by means of seals 23a, 23b, 12a, 12b and chamber walls 27, 28 sealed.
  • the support rollers 9-11 are radially reset with the cylinder piston units 25, as a result of which the casting ring 13 is released radially so that it can be removed.
  • a new casting ring is mounted and fixed radially and axially by the adjustment of the support rollers 9-11 engaging in the race 13a.
  • the cooling chamber is also automatically closed.
