- FIG. 1 schematically shows a device for descaling and subsequent hot-dip galvanizing of a metal strand
- Fig. 3 shows schematically a device for descaling the metal strand.
- a device is schematically outlined in FIG. 1, with which a metal strand 1 can first be descaled and then hot-dip galvanized.
- the metal strand 1 enters the system at a predetermined conveying speed v in the conveying direction R and is first guided between two S-roll stands 5 and 6, which exert a tensile force F on the metal strand 1.
- a means 4 for straightening the metal strand 1 is arranged between the two S-roll stands 5, 6. This means 4 is a stretch bending straightening machine.
- the metal strand 1 in the stretch-bending straightening machine 4 is bent or straightened by adjustable rollers under high tension by the tensile force F such that the metal strand 1 has a high degree of flatness after it has left the stretch-bending straightening machine 4 - he has.
- the metal strand 1 is fed to the device 2 for plasma descaling or cleaning.
- This device 2 has a treatment chamber 8 which is kept under a vacuum.
- a lock 19 or 20 is provided at the entry or exit of the metal strand 1 into or out of the treatment chamber 8.
- An S-roll stand 7 is also arranged in the conveying direction behind the device 2; in cooperation with the S-roll stand 6, it is thus possible to keep the metal strand 1 under tension when passing through the device 2 (tensile force F), so that in synergy with the stretch-bending straightening machine 4 it is ensured that the metal strand 1 is the device 2 with an extremely high degree of flatness. This is necessary to achieve a good descaling or cleaning result.
- a number of electrodes 9 are arranged in the treatment chamber 8, which are required to generate the plasma with which the surface of the metal strand 1 is descaled or cleaned. Details on this can be found in the aforementioned literature.
- a plurality of electrodes 9 are arranged one behind the other. These can all be activated for descaling or cleaning at the same time. h be supplied with electrical energy. However, it is also possible to selectively switch the individual module-like electrodes 9 in such a way that only the number of electrodes that is required to achieve a desired descaling or cleaning result is activated.
- a test device 10 is arranged in the conveying direction R behind the device 2 for plasma descaling or cleaning, which is able to inspect the surface of the metal strand 1 and to pass the result of the test on to a control device 11.
- the control means 11 acts on the drive (not shown) of the overall device in such a way that the conveying speed v of the metal strand 1 is influenced in such a way that the result of the descaling or cleaning of a desired specification corresponds.
- control means 11 can reduce the conveying speed v; as a result, the surface of the metal strand 1 is exposed to a longer exposure time to the plasma, which improves the descaling or cleaning result. If, however, there is already an excessively high, unnecessary quality, the control means 11 can provide an increase in the conveying speed v, so that the quality of the descaling or cleaning is reduced, but the productivity of the overall system is increased.
- an induction heating means 14 in the conveying direction R behind the device 2 for plasma descaling or cleaning, which can heat the metal strand 1.
- this can be an inductively heated annealing furnace with a protective gas atmosphere, with which it is possible to heat the metal strand 1 to a temperature of approximately 500 ° C. in a very short time.
- the metal strand 1 is then passed under protective gas and via a trunk, not shown, into a boiler 3 with liquid coating metal.
- a deflection roller 13 is arranged in the boiler 3, which deflects the metal strand 1 vertically upward after the coating with liquid coating metal.
- the induction heating means 14, the boiler 3 and the deflection roller 13 form the schematically represented means 12 for coating the metal strand 1.
- FIG. 2 An alternative embodiment of the system can be seen in FIG. 2. The difference from FIG. 1 is that in FIG. 2, the device 2 for plasma descaling or cleaning is followed by means 15 for rolling the descaled or cleaned metal strand 1. These agents are a multi-stand cold rolling tandem mill on which the metal strand 1 is rolled to the desired final thickness.
- the metal strand 1 is then fed to the stretch straightening machine or stretch-straightening machine 4, in which the strand 1 can be straightened by bending and applying a tensile force so that it has an optimal flatness before it enters the device 2 for plasma descaling or plasma cleaning arrives.
- the metal strand 1 passes through the lock 19, whereupon it is located in the treatment chamber 8, in which a vacuum prevails.
- the vacuum is generated by the vacuum pump 24.
- Descaling or cleaning takes place in the treatment chamber 8 by means of the plasma located between the electrodes 9 and the metal strand 1.
- the number of electrodes 9 depends on the belt speed v in order to ensure the required dwell time of the metal strand 1 in the plasma.
- the metal strand 1 runs through the vacuum lock 20 to the S-roll stand 7, which - as already explained - generates the high strip tension required for the most horizontal strip run possible in cooperation with the S-roll stand 6.
- support rollers 25 are arranged between the electrodes 9, which prevent sagging of the metal strand 1.
- Cold-rolled, oiled steel strip for example, must pass through special alkaline and electrolytic cleaning tanks with subsequent rinsing and sometimes also brushing before a metallic coating in order to achieve the required bare metal surface.
- Previously known systems also use chemical agents for this, which pose the environmental problems mentioned at the beginning.
- the use of plasma technology for cleaning the metal strand also brings great advantages here.
- control means 12 means for coating the metal strand
