Definitions
- the invention relates, according to the preambles of claims 1 and 3, a cold rolling mill and a method for cold rolling of metallic band, in particular of steel, with a single framework with means for setting a roll gap and with a cold rolling mill upstream Reel device for unwinding the tape and with a the Cold rolling mill downstream reel device for reeling the tape (See, for example, DE-A 4243045).
- WO 99/55474 is a Steckel mill for hot rolling with at least a Reversierwalzgerüst and this upstream and downstream Reels described. Between the reels and the reversing roll stand in each case a loop lifter is provided, the actual values for a tension control as well as providing mass flow control.
- a Stecketwalzwerk concerns but a hot rolling mill and thus no cold rolling process.
- Patent Abstracts of Japan & JP 60 231516 A relates to hot rolling and here in particular the formation of a reel device after a Fenjgwatz No.
- DE 42 43 045 A describes a cold rolling mill and a scheme for this. This includes a unwinding reel, two stands and a rewinding Reel. To achieve a constant tape thickness over the tape length, should the rolling force in dependence of the reduction in pre-calculated size kept constant. For this purpose, the rolling force of each rolling stand, the Roller speed and the belt tension matched. The belt speed between unwinding reel and the first rolling mill is influenced in such a way that the mass flow through the rolling mill per unit time is constant.
- the invention has the object based, a method for cold rolling and a cold rolling mill with a To provide a single framework, despite changing the band thickness profile and larger tape speeds no mass flow problems and / or the strip draw.
- the speed changes due to the change of the tape thickness in the Roll gap are largest on the inlet side of the single scaffold, so that the Tape storage is provided according to the invention at least in the inlet region. Since the disturbances due to the change in the band thickness profile, i. at a flexible rollers, also - but not so strong - on the outlet side Acting tape speeds is, according to a preferred embodiment proposed, also on the outlet side of the single scaffold one To arrange tape storage.
- the tape storage is a dancer roll.
- a Dancer roll or a dancer roll arrangement comprises one opposite the Band adjustable at a certain angle and with a certain force acted upon role, so that a loop forms in the band whose loop length changes with the position of the roll. That way, more can be done or less tape can be stored.
- FIG. 1 shows the coiled-up belt 8 with the aid of a reeling device 9 de-reeled and introduced into the rolling stand 1 in the arrow direction.
- a second reel device 10th coiled.
- a Dancer roller 6, 7 provided, which are identical and in Fig. 2 in detail with their Employment are shown.
- the single rolling mill 1 itself sits down in the shown Embodiment of two support rollers 11, two intermediate rollers 12th and the work rolls 13, 14 together. Any other arrangement of rollers in a single framework can also be used. Between the Roll stand 1 and the dancer rolls 6, 7 can, for example, on the outlet side (5) nor a marking device 15 may be arranged in the band line.
- Fig. 2 shows the mechanics and the regulation of a dancer roll 6 in a flexible Cold rolling.
- the dancer roll With the help of the employment of the dancer roll to the band 8 in the relationship to two adjacent rollers 16, 17, a loop is formed in the band 8, whose loop length is consistent with the position of the dancer roller 6 or their Angular adjustment in relation to the roller 16 changed. The deeper the dancer roll 6 dips into the band 8, the more band can be stored.
- the embodiment shown shows a hydraulic adjustment 18 for the dancer roll 6th
- the dancer roll 6 is associated with a force regulator 19.
- a force regulator 19 For the scheme will be Istkraft values and actual angle values of employment of the dancer roller 6 tapped. These actual force values are next to desired force values the force controller 19th fed. In this case, the desired force values are not specified, but off the tapped actual angle values and a predetermined Sollzug calculated.
- the force control loop gives the target actual force values as a result of the comparison a force correction value on the position 18, here a hydraulic piston-cylinder unit, the dancer roll 6. Over the force correction becomes a correction reached the tension of the tape.
- the tapped on the dancer roll actual angle value is also for the scheme the speed adjustment of the reels (9, 10) and thus about the torque control of the reels for mass flow control used.
- an angle controller For this purpose, an angle controller, the actual angle value and a given predetermined target angle.
- an angle correction value is calculated. This angle correction value is used to control the speed in the reels for Mass flow control.
- FIG. 3 shows the strip tension regulation by calculating a setpoint force for controlling the hydraulic adjustment of the dancer roller, starting from the Istkraft, while for mass flow control of the speed of the Reels takes place.
- the belt speed is entered as the setpoint. This one will too in the roller speed control as a setpoint.
- the band thickness control is shown in the flexible rollers.
- a flexible rolling process is the change of the roll gap and thus a change in the band thickness profile over the tape length known. It is thus predetermined a desired strip thickness course.
- This setpoint of the band thickness curve is used for feedforward control of the inlet side dancer roll.
- Out the desired band thickness curve is the change in the inlet velocity of Bandes calculated in the rolling stand and the necessary band tension control to maintain a constant strip tension. Due to the mass flow compensation the entry train can still be calmed down.
- the values for the desired strip thickness profile are given to a thickness controller, with the aid of actual strip thickness values, which are tapped on the inlet and outlet side be calculated, correction values for the strip thickness and these correction values passes on to a position controller, the roll gap setting in Cold rolling mill regulates.
