Definitions

the invention relates, on the one hand, to a process for producing a metal strip which can be wound into a coil in a horizontal strip casting plant and, on the other hand, to a horizontal strip casting plant for carrying out the process.
a conventional horizontal strip caster for producing a coil wound metal strip first comprises a furnace (holding furnace or hottop), at the outlet of which a cooled mold is flanged, which determines the cross section of the metal strip, see for example GB-A-2 004 783.
a Abziehhhim is arranged with several Abziehrollen.
the metal strip is passed between a plurality of horizontally extending Abziehrollen in the horizontal direction through the Abziehhü.
Abziehhrollen At least one Abziehrolle is driven. In general, however, several Abziehrollen be driven.
a milling unit for machining the surface of the metal strip can be integrated between the mold and the peeling unit.
the metal strip is guided in a horizontal plane further up to a unwinding unit.
the reel unit is provided with a plurality of bobbins that bend the metal strip so that it is deposited after exiting the Einroileinhek to a coil.
the coil is mounted on the roller unit provided above the winding rollers, horizontally extending support rollers.
the unrolling unit itself is roller-mounted and displaceable by the metal strip relative to a locally fixed machine bed.
a tape separating unit which is roll-supported in the longitudinal direction of the metal belt displaced and the metal strip separates when a Coll has reached its predetermined diameter.
the drives for the puller rollers, the belt separating unit and the winding rollers are coupled to each other via a programmable logic controller.
the production of the wound into a coil metal strip is carried out in a vocational step-like cycle, consisting of a preliminary stroke of about 15 mm and a return stroke of about 5 mm, wherein between the individual strokes each a break of approximately 2 seconds is inserted.
the relative acceleration of the metal strip amounts to approximately 4.5 cm / s 2 . Since during the entire production of the metal strip on the coil, the reeling unit is connected to the coil lying thereon and constantly growing in diameter, the take-off unit must have mass acceleration forces of up to about 25 t (reeling unit with about 4 t to 6 t growing coil of about 4 tons to 16 tons, and in the case of band separation also the band separation unit of about 2 tons). With further consideration of the belt pull-off force of about 2.5 t, a mass force of 250 kN must therefore be accelerated and decelerated in the cycle of the cycles.
the reel unit is moved from the stripping unit over the metal strip between two positions.
a limit switch causes the retractor to turn on and the retractor unit to move back to the home position along the metal belt.
another limit switch is actuated and switches the retracting drive off again.
the travel distance of the reel unit is approx. 500 mm.
the above-mentioned compositions are accelerated and decelerated intermittently up to thirty times a minute back and forth. Mitiliadem diameter of the coil and consequently also increasing weight, the opposing forces are getting bigger and thereby cause significant stresses on the bearings for the bobbins, but also the other bearings that need to be constantly maintained and frequently replaced for this reason.
the predetermined deduction parameters are falsified, so that a reproducibility of the cycles is not possible. A procedure with a higher number of cycles per minute is excluded. DE 2 236 388 discloses.
the invention is based on the prior art based on the object to provide a method for producing a wound into a coil metal strip and a horizontal strip caster for performing the method, which avoid high mass acceleration forces and make every single cycle reproducible.
the crux of the invention is the measure to synchronously drive at least one winding roller of the unwinding unit and at least one stripping roller of the stripping unit in the cycle of the forward stroke and the return stroke of the metal strip, that is to equip the stripping unit and the unrolling unit with synchronized drives.
the tape separation unit is also incorporated herein when it comes into action. In this way, the vocational-step-like cycle, consisting of a forward stroke and a shorter return stroke on the other hand, takes place only in the metal strip, the unavoidable minor shocks are compensated in the end phases of the cycles in the loop of the coil behind the last rolls of reel unit and the coil is formed.
the reeling unit therefore wraps synchronously with the peeling unit and, in principle, does not need to be moved.
the synchronous driving can be done with any drive unit. It is purely electrical (servo-three-phase drives), but also servohydraulic or purely mechanical drives conceivable.
each driven peel roller of the peel-off unit and each driven roller of the reel unit are coupled to each other via a programmable logic controller.
a programmable logic controller For several driven Abziehrollen and winding rollers are of course all Abziehrollen and all bobbins for themselves under the influence of a drive, which is then synchronized in each case via the programmable logic controller with the other drive.
the horizontal strip caster in a series arrangement on a spaced from a furnace (holding furnace or hot top) associated mold locally fixed peeling unit with several Abziehrollen on.
the Abziehrollen are preferably in pairs on top of each other and capture the metal strip between them.
the horizontal strip caster comprises a metal strip drawn in the longitudinal direction of the stripper unit from the mold in synchronism with this displaceable strip separating unit. This is used when a coil has reached the intended diameter or weight. Then it is moved at the speed of the metal strip over the period of the separation process.
the horizontal strip caster has a rolling unit which can likewise be displaced in the longitudinal direction of the metal strip and has a plurality of winding rolls.
the synchronized on their drives with the Abziehrolleln winding rollers are arranged above and below the metal strip that they detect the metal strip, continue and ultimately bend so that it is easily wound to the coil.
the reeling unit is therefore no longer displaced by the metal strip.
the feed force of the metal strip is deflected into a rotary movement of the coil.
This coil lies on support rollers in the reel unit.
the feed force is introduced into the rotary motion of the coil and thereby lifts in its linear motion.
the return stroke is compensated because of the minimum distance of about 5 mm in the loop that forms between the last pair of reels and the coil.
the illustrated in Figure 1 horizontal strip caster 1 comprises first a holding furnace 2, to which a cooled mold 3 is flanged.
a metal strip 4 in the embodiment of a copper alloy existing metal strip rectangular flat cross-section.
the metal strip 4 is then fed according to the arrow PF via support rollers 5 in a horizontal plane of a locally fixed peeling unit 6 with a plurality of paired pairing peeling rollers 7.
the Abziehrollen 7 are driven, wherein the unspecified illustrated drive via a control line. 8 is coupled to a programmable logic controller 9.
the removal rollers 7 are rotated after a certain cycle once in one direction and once in the other direction, whereby in the manner of a mit step in each case a forward stroke and a return stroke are generated. Through this cycle, the metal strip 4 in the mold 3 receives the desired quality.
each forward stroke is 15 mm and each return stroke 5 mm. There is a break of 2 seconds between strokes.
the force of the tape draw is approx. 2.5 t.
the relative acceleration of the metal strip 4 by the Abziehrollen 7 amounts to 4.5 cm / s 2 .
a strip separating unit 10 In the direction of movement of the metal strip 4, a strip separating unit 10 is provided with a pair of scissors 13 behind the peeling unit 6.
the weight of the scissors 13, which can be moved by the metal strip 4 in the case of a separating operation according to the double arrow PF1 on rollers 11 in a locally fixed roller bed 12, is approximately 2 t.
the scissor drive not shown is coupled via a control line 14 to the programmable logic controller 9.
the metal strip 4 is passed on behind the strip separating unit 10 in the horizontal direction and, after overflowing a further carrying roller 15, is fed to a reeling unit 16, as can be seen in more detail from FIG.
the unrolling unit 16 can be moved back and forth in accordance with the double arrow PF2 by means of rollers 17 on a locally fixed machine bed 18 over a distance X of approximately 50 mm.
the winding rollers 19 are under the influence of a non-illustrated drive, which is also coupled via a control line 20 to the programmable controller 9 in the Einrolltician 16 are a plurality of mutually associated winding rollers. With the help of this controller 9, the drives of the peeling unit 6 and the reeling unit 16 are synchronized in such a way that the winder rollers 19 have exactly the same speed as the peeling rollers 7.
the winding rollers 19 move the metal strip 4 in the reeling unit 16 further and deform it at the same time that it is wound after emerging from the reeling unit 16 to a coil 21, which also in the reeling unit 16 stored support rollers 22 is located.
the loop 23 of the metal strip 4 between the exit-side winding rollers 19 and the coil 21 serves to compensate for the return stroke of 5 mm.
the compensation distance X of approx. 50 mm is sufficient for this purpose.
the positional correction of the reeling unit 16 occurs in a period of about 10 hours, which means a relative movement of 0.001388 mm / s.
the arrows PF3 the winding direction of the metal strip 4 to the coil 21 is designated.
