Definitions
- the invention relates to a four-roll stand according to the preamble of claim 1 and a six-roll stand according to the preamble of claim 2 and a method for the optional operation of the four- or six-roll stand with thin and thicker work rolls in diameter.
- One or more roll stands can be found in a rolling mill.
- the rolling stock is gripped by the work rolls, which rotate against each other in the rolling direction. It is moved forward by the roll rotation of the work rolls. In the nip, the thickness of the rolling stock is reduced by the high pressure exerted by the work rolls.
- a four-roll stand (quarto) has two work and two backup rolls.
- a six-roll stand (six-high) has two work rolls, two support rolls and intermediate rolls arranged between the work rolls and the support rolls.
- thinner working rolls in diameter in the rolling stands at the rear in the rolling direction are advantageous. They reduce the rolling forces, the edge drop, the temperature loss of the rolling stock and may even make it possible to save roll stands in the rolling mill, because higher acceptances can be carried out.
- a hot rolling mill not only has to cover thin strips, but also a thickness range of, for example, 0.8 mm to 12.7 mm thickness in different hardness and different widths. Due to this requirement on the production spectrum, an optimization of the rolling mill on thin strips is not possible for the following reasons: The optimization presupposes that, for example, the last two roll stands in the production direction are operated with work rolls that are thinner in diameter. The drive pins and drive spindles of these thin work rolls would, however, be overloaded when rolling stronger and / or harder strips. Replacing the work rolls, which are thinner in diameter, with thicker work rolls requires a change of the drive spindles. However, the resulting standstill of the rolling mill is not acceptable.
- the work rolls themselves have no drive, but are at most connected to one another by means of a synchronous gear in order to avoid possible slippage of the work rolls.
- a rapid conversion of these roll stands to thicker work rolls is neither provided nor possible since the exclusive drive of the support rolls and the entrainment of the work rolls by friction on thicker work rolls is not possible.
- the invention is therefore based on the object of proposing a roll stand which allows rapid adaptation to rolling stock of different thicknesses and / or hardness.
- a roll stand which allows rapid adaptation to rolling stock of different thicknesses and / or hardness.
- it is proposed according to the invention for a four-roll stand that not only one of the support rolls is connected to a motor via a detachable device, but also that the other, opposite support roll is connected a detachable device is connected to a motor and the two work rolls are each assigned a detachable device which is connected to a motor.
- a releasable device which is connected to a motor, is assigned to the support rolls and work rolls or intermediate rolls and work rolls or support rolls and intermediate rolls which can be driven via drive spindles.
- This combined drive according to the invention in the four-roll or six-roll stand makes it possible to connect thick work rolls directly to a motor via the detachable device assigned to them, while when using thinner work rolls in a four-roll stand, the drive is carried out via the two backup rolls, which in in this case are connected to the motor via detachable devices.
- the thin work rolls are then only taken along by the backup rolls by friction.
- only the backup rolls and / or the intermediate rolls are connected to the motor via the detachable devices assigned to them, while for the operation of the thicker work rolls only the work rolls are connected to a motor via the detachable devices assigned to them.
- roller there is a connection between the roller and the motor only when there is a direct flow of force from the roller via the spindle, the detachable device and, if appropriate, an intermediate gear to the motor.
- a roller has no connection to the motor in the sense of this definition and is only taken along by friction from another, driven roller.
- Couplings that can be designed in particular mechanically, electrically, hydraulically or pneumatically are particularly suitable as a detachable device that enables the connection of the work rolls to the motor.
- the roll stands can also be designed in such a way that the hits of the drive spindles of the work rolls themselves act as a detachable device when these are pulled off the drive pins of the work rolls.
- the drive spindles can be designed telescopically to enable these withdrawal movements.
- a uniform and cost-effective drive of all rollers can be achieved if the support and work and, if necessary, intermediate rollers are driven by a common motor via a gear, in particular via a worm gear.
- a common motor in particular via a worm gear.
- Thin work rolls with a low-wear material in particular powder-metallurgical work rolls (high-strength HSS rolls) are preferably used in the roll stands according to the invention. These work rolls can be produced, for example, according to the HIP (hot isostatic pressing) process.
- HIP hot isostatic pressing
- Figure 1 shows a four-roll stand when operating thin work rolls as well
- Figure 2 shows a four-roll stand when operating thicker work rolls.
- FIG 1 the backup rolls 1 and 2 of a four-roll stand are shown schematically, between which thin work rolls 4 and 5 are provided for a rolling stock 3 of low thickness.
- a drive motor 7 equipped with a comb roller gear 6 serves to drive the rollers 1, 2, 4, 5.
- the comb roller gear 6 consists of the two middle work roller gear wheels 8, 9 and an upper and a lower backup roller gear wheel 11, 12.
- Both the support rollers 1, 2 and the work rollers 4, 5 are each assigned drive spindles 13, 14, 15, 16, which are connected to the motor 7 via the comb roller gear 6.
- the associated with the support rollers 1 and 2 Drive spindles 13, 16 each have a clutch 17, 18, which in the disengaged state interrupt the flow of force between the support rollers 1, 2 and the motor 7.
- the clutches 17, 18 are engaged in order to drive only the support rolls 1, 2, while the drive spindles 14, 15 assigned to the thin work rolls 4, 5 run loosely.
- the detachable device assigned to the thin work rolls 4, 5 consists of the hits 19, 21, which are located on the ends of the spindles 14, 15 opposite the comb-rolling gear 6 and are provided for this purpose, with the drive pins of diameter to work together with thicker work rolls. Since the work rolls 4, 5 shown in FIG. 1 have no drive pins, the flow of force between the thin work rolls 4, 5 and the motor 7 is interrupted.
- the four-roll stand according to FIG. 2 differs from that according to FIG. 1 in that the two support rolls 1, 2 are connected directly to a separate support roll motor 26, 27 via their drive spindles 13, 16. However, this difference is meaningless for the way it works.
- the thicker work rolls 24, 25 now have drive pins 28, 29 which cooperate with the hits 19, 21 of the drive spindles 14, 15.
- the frictional connection from the thicker work rolls 24, 25 is thus produced via the spindles 14, 15 and the comb rolling gear 6 to the motor 7, which in this embodiment only drives the work rolls 24, 25.
- the clutches 17, 18 of the drive spindles 13, 16 for the support rollers 1, 2 are disengaged, so that the support rollers 1, 2 run ineffectively while the support roller motors 26, 27 are switched off.
- step wedges are arranged on both the top and bottom of the stand. All drive spindles are designed in a manner known per se as cardan shafts in order to compensate for the offset to the attachment points of the drive spindles which are fixedly arranged on the transmission or motor side.
- the invention allows rapid adaptation to rolling stock of different thicknesses and / or hardness, in that the rolling stands can be operated either with thin or thicker work rolls with little effort.
- the combined drive in the four-roll or six-roll stand proposed according to the invention for this purpose makes it possible to connect thick work rolls directly to a motor, while thin work rolls are only taken along by friction from adjacent support or intermediate rolls.
