Definitions
- the invention relates on the one hand to a method for producing a coil windable metal strips in a horizontal strip caster and the other one Horizontal belt caster to carry out the process.
- a conventional horizontal belt caster for producing a coil wound metal strip initially comprises an oven (holding oven or hottop), at the outlet is a chilled mold flanged, which has the cross section of the Metal bands determined, see for example GB-A-2 004 783.
- a pulling unit with several pulling rollers is arranged at a distance from the mold.
- the metal strip is between several horizontally extending pulling rollers passed in a horizontal direction through the pulling unit. From the peel rollers is driven at least one pulling roller. However, there are usually multiple peel rollers driven.
- a milling unit can be placed between the mold and the pulling unit be integrated for processing the surface of the metal strip.
- the reeling unit is provided with several winding rolls, which bend the metal strip so that it comes out after exiting the curling unit a coil is deposited.
- the coil is on in the reeling unit above the winding rolls provided, horizontally extending support rollers.
- the roll-in unit itself is on roller bearings and is relative to one by the metal band fixed machine bed relocatable.
- a belt cutting unit that is roll-supported in the longitudinal direction of the metal strip is displaceable and the metal strip separates when a coil is has reached a predetermined diameter.
- the drives for the pull-off rollers, the tape cutting unit and the winding rollers are Coupled together via a programmable logic controller.
- the metal strip that can be wound into a coil is produced in a pilgrim-like cycle, consisting of a forward stroke of approximately 15 mm and a return stroke of approximately 5 mm, with a pause of approximately 2 seconds between the individual strokes.
- the relative acceleration of the metal strip is approximately 4.5 cm / s 2 . Since the roll-in unit is connected to the coil lying thereon and the diameter of the coil is constantly increasing during the entire production of the metal strip on the coil, mass pulling forces of up to about 25 t (roll-in unit with approx. 4 t to 6 t, that in diameter) must be used with the pulling unit growing coil with approx. 4 t to 16 t and in the case of strip separation also the strip separation unit with approx. 2 t) can be mastered. Taking into account the strip pulling force of approx. 2.5 t, a mass force of 250 kN must be accelerated and braked in time with the cycles.
- the roll-in unit is pulled from the pull-off unit via the metal strip between two Positions shifted.
- a limit switch causes the Einrollantrieb to switch on and the roll-in unit moves back along the metal band to the starting position emotional. If this starting position is reached, another limit switch is actuated and switches the curling drive off again.
- the traversing path of the rolling unit lies at approx. 500 mm. In this procedure, the above are therefore given Masses intermittently accelerated back and forth up to thirty times a minute as well as slowed down. With increasing diameter of the coil and consequently even as the weight increases, the opposing forces become larger and larger cause considerable stresses on the bearings for the Winding rolls, but also the other bearings that are constantly serviced for this reason and need to be replaced frequently. In addition, the default Falsification parameters falsified, so that the cycles cannot be reproduced is possible. A procedure with a higher number of cycles per minute is locked out.
- the invention is based on the object Method for producing a metal strip wound into a coil, and a Horizontal belt caster to implement the process, which Avoid high mass acceleration forces and reproducible every single cycle do.
- the key point of the invention is the measure of at least one winding roll of the rolling unit and at least one peeling roller of the peeling unit in the cycle of the forward stroke and the return stroke of the metal strip to drive synchronously, that is, the pulling unit and to equip the rolling unit with synchronized drives.
- the Tape separator is included here when it takes action. In this way finds the vocational-like cycle, consisting of a forward stroke and a counter stroke shorter return stroke in length, only in the metal band instead, the unavoidable minor impacts in the end phases of the cycles in the loop of the coil can be compensated for, which is behind the last winding rolls of the single-reel unit and trains the coil.
- the roll-in unit therefore winds synchronously with the Puller unit and in principle no longer needs to be moved.
- the synchronous driving style can be done with any drive unit. There are purely electrical (three-phase servo drives), but also servo-hydraulic or pure mechanical drives imaginable.
- such a horizontal belt caster is arranged in a row one at a distance from one assigned to an oven (holding oven or hottop) Chill mold locally fixed puller unit with several pulling rollers.
- the peel rollers preferably lie in pairs one above the other and grasp the metal strip between them.
- the horizontal belt caster comprises one in the longitudinal direction of the the pulling unit from the mold pulled metal strip synchronously with this displaceable Ribbon cutting unit. This is used when a coil meets the intended Diameter or the intended weight has reached. Then she will at the speed of the metal strip over the period of the cutting process emotional.
- the horizontal belt caster also has a longitudinal direction of the metal strip relocatable single unit with several winding rolls.
- the winding rollers synchronized with the pulling rollers via their drives are of this type arranged above and below the metal band so that they grip the metal band, continue and ultimately bend so that it is easily wound into the coil.
- the roll-in unit is therefore no longer moved by the metal strip.
- By the Feeding the metal strip exclusively through the pulling unit becomes the feed force of the metal strip is deflected into a rotary movement of the coil.
- This coil lies on support rollers in the roller unit.
- the return stroke is due to the minimum distance of about 5 mm compensated in the loop, which is between the last pair of winding rolls and trains the coil.
- the horizontal strip caster 1 illustrated in FIG. 1 initially comprises a holding furnace 2, to which a cooled mold 3 is flanged.
- a metal strip 4 emerges from the mold 3, in the exemplary embodiment from a Copper alloy existing metal strip of rectangular flat cross section.
- the Metal strip 4 is then according to the arrow PF on support rollers 5 in a horizontal Level of a locally fixed pulling unit 6 with several pairs assigned to each other Pull rollers 7 fed.
- the pull rollers 7 are driven, the Drive not illustrated in detail via a control line 8 with a programmable logic controller Controller 9 is coupled.
- the pull rollers 7 are once in a and after a certain cycle once turned in the other direction, making each like a mitage step a forward stroke and a return stroke are generated. This cycle gives the metal strip 4 in the mold 3 the desired quality.
- each forward stroke is 15 mm and each return stroke is 5 mm. There is a 2-second pause between strokes.
- the force of the tape pull is approx. 2.5 t.
- the relative acceleration of the metal strip 4 by the pulling rollers 7 amounts to 4.5 cm / s 2 .
- Belt separation unit 10 is provided with scissors 13.
- the weight of the by that Metal strip 4 in the case of a separation process according to the double arrow PF1 on rollers 11 scissors 13 movable in a locally fixed roller bed 12 is approximately 2 t.
- the scissor drive (not shown in more detail) is also connected via a control line 14 the programmable logic controller 9 coupled.
- the metal strip 4 is passed horizontally behind the strip separation unit 10 and after a further support roller 15 has run over a roller unit 16 supplied, as can be seen in more detail in Figure 2.
- the rolling unit 16 is on a roller 17 Locally fixed machine bed 18 back and forth over a distance X of approximately 50 mm traversable.
- the rolling unit 16 there are a plurality of pairs assigned to one another Winding rolls 19.
- the winding rolls 19 are not under the influence of one illustrated drive, which also via a control line 20 with the programmable logic controller 9 is coupled.
- this control 9 the drives of the pulling unit 6 and the rolling unit 16 are synchronized in such a way that the winding rollers 19 have exactly the same speed as the pulling rollers 7th
- the winding rollers 19 also move the metal strip 4 in the rolling unit 16 and deform it at the same time, that it is wound into a coil 21 after it leaves the rolling unit 16, which lies on support rollers 22 which are also mounted in the rolling unit 16.
- the Loop 23 of the metal strip 4 between the outlet-side winding rollers 19 and the coil 21 serves to compensate for the return stroke of 5 mm. That’s enough Compensation distance X of approx. 50 mm.
- the position correction of the rolling unit 16 takes place in a period of about 10 hours, which is a relative movement of 0.001388 mm / s means.
- the arrows PF3 indicate the winding direction of the metal strip 4 to the coil 21.
