Definitions
- the invention relates to a method for an improved procedure in a winding process for metal strip in the context of a reversing processing of metal strip in a hot rolling mill.
- a so-called ⁇ Steckel Mill threading the tape for intermediate heating into the slot or gap of the winding drum of the reel furnace.
- the winding drum of the winding furnace, on which the tape is to be wound up stands still. After completing the threading process, the winding drum is accelerated to wind up the tape and train between reel and scaffolding.
- the object of the present invention is to reduce or avoid the above disadvantages.
- the object of the invention is therefore to provide a method and an apparatus by means of which a trouble-free as possible threading is made possible in the coiler oven.
- the procedural part of the object is achieved by a method for operating a winding drum of a coiler furnace for a reversing working hot rolling mill, wherein a wound on the winding drum belt length is determined in depen ⁇ tion of a rotation angle of the winding drum, wherein the winding drum on the winding ⁇ length as a function of time is determined, wherein a first, smaller angle or a first point of the winding drum circumference in the winding direction and a second, larger angle or a second arranged in the winding direction behind the first point point of the winding drum circumference are given to which at least or at the latest a strip tension between rolling stand and winding drum is to be constructed, wherein the winding drum is operated such that between the smaller angle or the first point and the larger angle or the second point at least one angle or a winding drum peripheral point exists in which the length of tape winding up on the winding drum, as a function of a rotation angle, is equal to the length of tape wound on the winding drum as a function
- ⁇ sondere can be set so the first and second angle or first uznd second point is that these angles or points coincide.
- the "or" in the above formulation is to understand that either the angle and / or the perimeter points used to carry out the method ⁇ the.
- a time curve of the minimum traveling Wi ⁇ ckeltrommel to be maintained within the framework of technical and / or technological boundary conditions, in particular to technical limitations of the drive of the winding drum, is determined.
- the time-minimum travel curve for the smaller angle and the larger angle is determined.
- the band length is determined as a function of time for the smaller and the larger angle from the determined time.
- the adjustment of the angle at which the length of tape wound up on the winding drum as a function of a rotation angle becomes equal to the length of tape wound on the winding drum depending on the time is set by adjusting the belt speed.
- the belt speed in this case is a free parameter which provides the flexibility to adjust the angle at which the belt length as a function of the angle of rotation is equal to the belt length wound on the winding drum as a function of time.
- the adjustment of the angle at which coiling on the winding drum tape length in response to a Drehwin ⁇ angle is equal to the up-winding on the winding drum tape length in a function of time, by changing the angle within the smaller and larger angle.
- This is an alternative pre ⁇ hens, to use the belt speed as free Pa ⁇ parameters. This allows a trouble-free as possible and time ⁇ minimal initial winding, by setting the angle between the smaller and the larger angle at which the to coiling on the winding drum tape length depending on the angle of rotation equal to the up-winding on the winding drum tape length in function of time is, is variably adjustable.
- Advantages of the invention are, in particular, that in the off ⁇ configurations of the present invention, the geometry of the Wi ckelvoriques, in particular of drive rolls, idler pulley, Wi ⁇ ckeltrommel, particularly in a determination of the travel curve is considered.
- the determined drive curves be Wegsichti ⁇ gen drive limits, especially taking into account the for the turn of the tape head required moment.
- ⁇ sondere can be lowered the predetermined by the travel curve on the driving acceleration as the drive of a uniform acceleration due to the need for the turning moment of the tape could not follow.
- a feed-forward control which is used to compensate a speed break-in, caused by the bending of the material. This disturbance on the circuit is preferably carried out as feedforward control.
- the tape speed required for threading can also be reduced.
- the winding nip is the opening of the winding drum into which the tape head is inserted in order to dishevel the tape.
- According to the invention can be driven at excessive speed in the temporal areas in which the tape hangs freely. That
- tape length is caught up in comparison to the prior art, so that to achieve the angle at which train is built, can be used on a much smaller value for the leadership factor as in the old solution. That the speed increase of the drum or winding drum relative to the band is significantly smaller. This noticeably reduces the jerk during winding.
- the invention provides the advantage that at slow belt speeds or large angles at which a tensile structure occurs, the accelerations occurring vergli chen are reduced to the prior art, which contributes to an increase in the life of the mechanism. It is also advantageous that already in the braking phase, the torque limit of the drive can be reduced according to the train setpoint. This results in a lower risk of the band break or the withdrawal of the tape from the slot or winding nip.
- control and / or regulating device for a winding drum of a coiler furnace of a reversing working hot rolling mill, with a machine-readable program code comprising control commands, which cause the control and / or regulating device for performing the method according to one of claims 1 to ,
- a device from a hot rolling mill for reversibly hot rolling of rolling stock with at least one reel furnace comprising a winding drum and a control and / or regulating device according to claim 9, wherein the winding drum and the control and / or regulating device are operatively connected.

- the deposit of the machine-readable program code 9 can take place by means of a storage medium 8.
- control and / or regulating device can have a programmable storage medium on which the program code can be stored for execution.
- the program code 9 can also be transmitted to the control and / or regulating device 7 via a network.
- FIG. 2 shows a flowchart which can be used as an example on the control and / or regulating device in order to control or regulate the application of hot strip after a rolling pass. The flow chart assumes that the hot strip has not yet reached the winding drum, but in the near future, a winding of hot strip is intended.
- the wound on the drum or winding drum angle-dependent band ⁇ length 1 (phi) is determined as a function of its rotational angle phi.
- input parameters here are taken into account: eg the geometric structure of the winding system incl. Positions of Um ⁇ guide roller and the driver roller, the radius of the winding drum, and an angle to which the tape is further fed into the slot or winding nip.
