Definitions
- the invention relates to a method for descaling a metal strip, in particular a hot rolled strip of normal steel or a hot or cold rolled strip of austenitic or ferritic stainless steel, in which the metal strip is guided in a conveying direction through at least one plasma descaling device in which he Plasma descaling is subjected. Furthermore, the invention relates to a device for descaling a metal strip.
- a generic method or a generic device are eg off JP-A 06279842 known.
- the pickling of steel strip is carried out in continuous lines, the process part of which can have a very long length depending on the strip speed. Such systems therefore require very high investments.
- the pickling process also requires a great deal of energy and wastewater disposal and regeneration of hydrochloric acid, which is commonly used in mild steel.
- the strip passes between electrodes arranged above and below the strip through a vacuum chamber.
- the plasma is located between the electrodes and the tape surface on both sides of the tape.
- the effect of the plasma acting on the scale is the removal of the oxides on the strip surface, which is associated with an increase in the temperature of the strip; This can be very disadvantageous.
- the increase in temperature may result in the formation of an oxide film on the belt surface as the descaled belt exits the vacuum in air, which is not permitted for further processing such as cold rolling or direct hot strip processing.
- the invention is therefore based on the object to provide a method and an associated device for descaling a metal strip, with which it is possible to achieve a quality increase in the production of the metal strip, in particular by preventing oxidation processes, without the microstructure of the metal strip negative influence.
- the solution of this object by the invention according to the method is characterized in that the metal strip is subjected to the plasma descaling in at least one plasma descaling device in a cooling device in such a controlled cooling that it has a defined temperature behind the cooling device.
- the metal strip is subjected to plasma descaling at least twice, each time with subsequent controlled cooling.
- Oxidation of the descaled metal strip in the ambient atmosphere is prevented by the last controlled cooling in the conveying direction being such that the metal strip leaves the last cooling device in the conveying direction at a temperature of less than or equal to 100 ° C.
- the microstructure of the metal strip is not adversely affected by the plasma descaling in each of the plasma descaling devices being such that the metal strip behind the plasma descaling device has a temperature of at most 200 ° C.
- the cooling of the metal strip in the at least one cooling device takes place in that the metal strip is brought into contact with a cooling roller via a predeterminable wrap angle.
- the cooled roll dissipates heat on contact with the metal strip therefrom.
- the metal strip is held under tension at least in the area of contact with the cooling roller.
- the metal strip is cooled at least substantially to the same temperature in each of the cooling subsequent to the plasma descaling. It is also advantageous if, alternatively or in addition thereto, the metal strip is cooled at least essentially by the same temperature difference in each of the cooling subsequent to the plasma descaling.
- the cooling of the metal strip in the one or more cooling devices is preferably carried out under reduced pressure relative to the ambient pressure, in particular under vacuum.
- the cooling of the metal strip takes place in the last cooling device in the conveying direction under a protective gas, in particular under nitrogen.
- the device for descaling the metal strip has at least one plasma descaling device, through which the metal strip is guided in the conveying direction.
- the device is characterized by at least one cooling device arranged in the conveying direction behind the plasma descaling device, which is suitable for the controlled cooling of the metal strip to a defined temperature.
- a temperature sensor is arranged, which is in communication with a control device which is suitable for influencing the cooling device with respect to the cooling power generated by it and / or the conveying speed of the metal strip.
- At least two plasma descaling devices are provided, to each of which a cooling device is connected.
- each cooling device has at least three cooling rollers, which are arranged and movable relative to each other, that the wrap angle between the metal strip and the roll surface is variable.
- the cooling capacity applied by the cooling device to the metal strip can be influenced, i. H. how much the cooling device cools the metal strip.
- Movement means are therefore preferably provided with which at least one cooling roller can be moved relative to another cooling roller perpendicular to the axes of rotation of the cooling rollers.
- the cooling rolls are preferably liquid-cooled, in particular water-cooled.
- means for generating a tensile force in the metal strip may be provided, at least in the region of the cooling devices. This ensures a good contact of the metal strip on the cooling rolls.
- At least two plasma descaling devices and at least two downstream cooling devices are arranged in a straight line.
- An alternative to this, which is space-saving, provides that a plasma descaling device is arranged so that the metal strip is guided vertically upwards (or downwards) in it, and another plasma descaling device is arranged so that the metal strip in her vertically down (or up) is performed with a cooling device is disposed between the two plasma descaling.
- a good cooling effect of the cooling rollers can be achieved if they have on their lateral surface a coating with a wear-resistant and highly thermally conductive material, in particular with hard chrome or ceramic.
- the metal strip to be descaled has a very good and unoxidized surface following descaling, so that the subsequent operations can be carried out with high quality.
- the invention thus ensures that the metal strip is cooled during and after the descaling controlled to a temperature which is below the temperature at which an oxidation or tarnishing on the strip surface can occur in air.
- a metal strip in particular a hot rolled strip of normal steel, in which the metal strip is guided in a conveying direction through at least one plasma descaling device in which it is subjected to plasma descaling, it can be provided that the plasma descaling directly or indirectly Coating the metal strip is followed by a coating metal, in particular a hot dip galvanizing of the metal strip.
- the energy introduced by the plasma descaling into the metal strip can be used to preheat the metal strip prior to coating.
- the metal strip is preferably first plasma-demineralized in a coupled system and then coated, in particular hot-dip galvanized.
- the metal strip preheated by the plasma descaling is preferably conducted without air access from the plasma descaling into the protective gas atmosphere of a continuous furnace required for the coating, where the strip is further heated to the temperature required for the coating.
- the band heating can be done inductively after the plasma descaling according to the "heat-to-coat" method. In this case, the band, in particular the too galvanized hot strip, very quickly under a reduced atmosphere to 440 ° C to 520 ° C, in particular to about 460 ° C, are heated before it enters the coating.
- the plasma descaling downstream coating can be carried out according to the conventional method with deflection roller in the coating container or by the vertical method (Continuous Vertical Galvanizing Line - CVGL method), in which the coating metal is retained in the coating container by an electromagnetic closure.
- the metal strip dives only very briefly into the coating metal.
- the plasma descaling system can be coupled to a continuous furnace for hot dip galvanizing of hot-rolled steel strip, wherein on the outlet side of the plasma descaling a vacuum lock and on the inlet side of the continuous furnace furnace sluice of conventional design can be located, which are connected to each other gas-tight.
- the strip must be heated to a temperature which is about 460 ° C to 650 ° C, depending on the heating rate.
- the strip heating arising during plasma descaling can be used as preheating of the strip before it enters the continuous furnace, thereby achieving an energy saving and a shortening of the furnace.
- Fig. 1 is a device for descaling a steel strip 1 to see, this system is designed in a horizontal design.
- the steel strip 1 coming from a uncoiler 19 is directed in a stretch-bending machine 20 with the associated S-roll stands 21 and 22 so that the metal strip 1 has the greatest possible flatness before the strip enters the process part of the system under high tension.
- the belt 1 enters a first plasma descaling device 2 in which the vacuum required for plasma descaling is generated and maintained by means of known vacuum pumps.
- the plasma descaling device 2 are located on both sides of the belt 1 arranged electrodes 24, which generate the plasma required for descaling.
- the plasma heats the strip surface on both sides, resulting in a heating of the entire strip cross-section to a temperature of max. 200 ° C at the end of the plasma descaling device 2 can lead.
- the amount of band heating over the total cross-section depends mainly on the conveying speed v of the metal strip 1 and the strip thickness for the same energy of the plasma, with increasing strip speed v and strip thickness, the band heating is lower.
- the not yet completely descaled belt 1 runs in a cooling device 4 provided with cooling rollers 6, 7, 8 which is connected in a gas-tight manner to the plasma descaling device 2 and in which the same vacuum prevails as in the plasma descaling device 2 ,
- the belt 1 runs around the cooling rollers 6, 7, 8, the circumference of which is cooled from the inside with water, which dissipates the heat through a cooling circuit.
- the high strip tension causes the band 1 - the cooling rollers 6, 7, 8 wrapped around - good at these, in order to ensure the highest possible heat transfer.
- the cooling rollers 6, 7, 8 wrap around the metal strip 1 alternately from above and from below. Preferably, three to seven cooling rolls are provided.
- the cooling water for cooling the cooling rolls is fed continuously via rotary feedthroughs and discharged again.
- the arrangement shown are three cooling rollers 6, 7, 8 in the cooling device 4, which are driven individually. Depending on the performance and maximum belt speed v of the system, more cooling rollers are possible and useful.
- On the inlet side and the outlet side of the cooling device 4 are temperature sensors 12 for continuously measuring the temperature of the metal strip 1.
- the cooling rollers 6, 7, 8 for example, in the vertical direction of the wrap angle ⁇ (s. FIG. 3 and FIG. 4 ) and thus the cooling capacity of the cooling device 4 are regulated, which acts on the metal strip 1.
- the maximum strip temperature should be about 100 ° C.
- the cooled strip 1 passes into a second plasma descaling device 3, which is connected in a gastight manner to the cooling device 4 and in which the same vacuum as in the first plasma descaling device 2 is produced by means of vacuum pumps.
- the second plasma descaling device 3 which is constructed similarly to the first one, the complete descaling of the strip 1 which has not yet completely descaled in the first plasma descaling device 2 takes place.
- the strip 1 heats up similarly as in the plasma descaling device 2 to a final temperature, which is dependent on the belt speed v and the belt cross-section about 100 ° C to 200 ° C above the inlet temperature in the plasma descaling device 3.
- the belt 1 passes through a gas-tight lock 25 into the second cooling device 5 filled with protective gas (eg nitrogen), which is provided with cooling rollers 9, 10, 11 as the first cooling device 4.
- protective gas eg nitrogen
- the individual plasma descaling devices 2 and 3 or more of these devices are all designed to be the same length.
- the number of cooling rollers 6, 7, 8, 9, 10, 11 depends on the performance of the system.
- the belt 1 is cooled by the cooling rollers 9, 10, 11 to a final temperature not exceeding 100 ° C.
- temperature sensors 13 for measuring the strip temperature are again located on the inlet side and outlet side of the cooling device 5.
- another gas-tight lock 26 At the end of the cooling device 5 is another gas-tight lock 26, which prevents the entry of air into the cooling device 5. This measure ensures that the strip 1 exits the process part of the line at a maximum temperature of 100 ° C. and that the bare surface of the strip can not be oxidized by atmospheric oxygen.
- a train roller stand 18 consisting of two or three rollers which applies the required strip tension or holds it together with the S-roller stand 22.
- the elements marked with the reference numerals 17 and 18 thus represent means for generating a tensile force in the belt 1.
- the tensile force generated in the belt 1 serves to ensure good contact of the belt 1 to the cooling rollers 6, 7, 8, 9, 10, 11 to ensure.
- the tape 1 passes through the necessary other facilities, such as tape storage and Bekladschere, to the reel 27 (as shown) or other coupled devices, eg. B. to a tandem mill.
- the proposed plasma entrainment system can have one or more plasma descaling devices 2, 3 with adjoining cooling devices 4, 5.
- the embodiment according to Fig. 1 depends on two such units. If only one cooling device 4 is used, this is similar to the second cooling device 5 described here with the associated locks 25 and 26 are formed.
- Fig. 2 shows an alternative embodiment of the plant for the descaling of steel strip 1, in which the plasma descaling devices 2 and 3 are arranged vertically (vertically). All functions in this system are identical to those in Fig. 1 explained attachment.
- a vertical arrangement may, under certain conditions, be more favorable than a horizontal arrangement because of its shorter length.
- FIGS. 3 and 4 It can be seen how by vertical displacement of the cooling roller 7 (see double arrow), which is located between the two cooling rollers 6 and 7, the wrap angle ⁇ of the belt 1 about the rollers 6, 7, 8 can be changed (entered for the wrap angle around the roller 7), which also changes the heat transferred from the metal strip 1 to the cooling rollers 6, 7, 8 heat flow.
- the vertical displacement of the central cooling roller. 7 takes place by means of movement 16, which are shown schematically and in the present case designed as a hydraulic piston-cylinder system.
- FIG. 5 A solution is sketched in which the heat introduced by the plasma descaling into the metal strip is used to coat the strip with a coating metal immediately after descaling.
- Fig. 5 shows the process part of a coupled plasma descaling and hot-dip galvanizing line for hot rolled steel strip.
- the strip 1 after being stretch-straightened in the stretch-bender 20 (stretch-straightening unit), passes through a vacuum lock 23 into the plasma descaling device 2 where it descalculates to about 200 ° C to 300 ° C, depending on the belt speed and belt thickness is heated.
- the belt 1 passes through a vacuum outlet lock 25 and through the furnace inlet lock 29 connected thereto into a continuous furnace 28.
- a pair of draw rollers 30 hot letter, which has the required high strip tension in the plasma descaling device 2 generated.
- the belt temperature is measured with a temperature sensor 12, via which the required further belt heating in the continuous furnace 28 is controlled. From the point of the sensor 12, the belt 1 passes through the inductively heated continuous furnace 28, in which it is heated very quickly to about 460 ° C after the "heat-to-coat" process. Subsequently, the tape passes over a trunk 31 in the coating container 32, where it is hot-dip galvanized. With the wiping nozzles 34, the layer thickness is regulated. In the adjoining air cooling section 35, the metal strip 1 is cooled and then fed to the further required process steps, for example, the temper rolling, the straightening and the chromating.
