Definitions
- the invention relates to a device for processing at least one surface of continuous strip material made of non-ferrous metal according to the preamble of claim 1, and a corresponding method according to the preamble of Claim 16.
- strip casting plants e.g. hot rolling plants with roller, ingot or strip casting machine
- cast strips made of non-ferrous (NF) metals, in particular aluminum or aluminum alloys are generally hot-rolled directly from the casting heat.
- NF non-ferrous
- contamination of the surface can occur in a layer thickness of up to 50 ⁇ m, which is brought in by the casting process.
- these impurities are rolled into the material in the subsequent rolling passes and can no longer be efficiently removed in later process stages.
- the impurities close to the surface have a negative effect on the subsequent process steps and the surface quality characteristics.
- Chemical cleaning processes such as pickling, are not suitable for cast-warm rolling stock.
- the object of the invention is to optimize the abrasive surface treatment of non-ferrous metals, in particular in the form of aluminum strips, with technically simple means for cleaning purposes.
- the invention provides a device for processing at least one surface of continuous strip material made of non-ferrous metals, which in particular has aluminum or aluminum alloys or consists of these materials.
- the device according to the invention comprises at least one rotating round brush, the length of which can be brought into contact with at least one surface of the strip material.
- This round brush has a diameter of 200 mm to 1000 mm.
- the diameter of this round brush can preferably be between 200 and 500 mm, more preferably between 250 and 400 mm
- the invention also provides a method for processing at least one surface of continuous strip material made of non-ferrous metals, in which the strip material is moved in a strip running direction and at least one rotating round brush is brought into contact with at least one surface of the strip material with its body length and is driven by a motor drive.
- the rotating round brush rotates at a speed of 100 to 3,600 rpm due to the motor drive.
- the rotating round brush is preferably set in rotation by the motor drive at a speed of 1,200 to 1,800 rpm.
- a motor drive for this purpose, which is operatively connected to the rotating round brush and drives it about an associated axis of rotation.
- This motor drive is connected to a control device in terms of signals.
- the control device is programmed in such a way that the rotating round brush can rotate at a speed of 100 to 3,600 rpm.
- the rotating round brush can preferably rotate or be set in rotation at a speed of 1,200 to 1,800 rpm by means of the motor drive and the control device connected thereto by signals.
- a gear it is possible for a gear to be arranged or interposed between the motor drive and the rotating round brush. By using such a gear, it is possible to reduce or increase the speed of the motor drive in the direction of the rotating round brush and thus to achieve the stated values for the resulting speed of the rotating round brush.
- the feature “surface of the strip material” means a surface that comes into contact with rollers or is rolled in a rolling mill in the further course of processing of the strip material.
- the use or arrangement of the rotating round brush(es) takes place in such a way that a layer near the surface of the strip material is removed or removed immediately after the casting process and thus before the first rolling pass. This prevents unwanted impurities, for example in the form of mold powder inclusions, from being rolled into the strip material.
- surface defects such as those caused by indentation marks from the casting process, e.g. joint marks, are removed by removing the layer near the surface.
- the present invention is based on the essential finding that by means of the mentioned diameter of the round brush, which can be in the range of 200 mm to 1000 mm, or the characteristic speed of 100 to 3,600 min 1 , with which this rotating round brush around its axis of rotation is driven, the result is that the brushes or hairs on the outer circumference of the round brush are exposed to a sufficiently large centrifugal force and thus dirt or impurities brushed off the belt surface, which first get stuck on the outer circumference of the rotating round brush or on its brush trimmings, then effectively ejected to the outside.
- this results in an advantageous self-cleaning for the rotating round brush, which is associated both with an improvement in the surface quality of the processed strip material and with an increase in the service life of the round brush.
- the round brush has a diameter of 200-500 mm, preferably 250-400 mm. With such a diameter, it is advantageously achieved that the round brush is sufficiently compact on the one hand to achieve targeted local processing of the surface of the strip material, and on the other hand the brushes or hairs on the outer edge of the round brush are exposed to a sufficiently high centrifugal force, as explained above so that dirt can be ejected radially outwards from the brushes.
- the removed layer thickness is preferably in a range from 1 ⁇ m to 200 ⁇ m.
- Such a removal can be global or partial.
- abrasive processing of at least one surface of the strip material by means of brushes has the advantage that a variable layer thickness removal is possible, which has no influence on the processing quality and thus on the appearance of the surface of the strip material.
- targeted processing of the strip material on at least one surface of it can be improved in that the rotating round brush, which is brought into contact with this surface, is not only moved in rotation about its axis of rotation, but also relative to the direction of travel of the strip material can.
- the rotating round brush it is possible for it to be arranged to move back and forth in translation transversely to a direction of travel of the strip material.
- the rotating round brush it is also possible for the rotating round brush to be arranged such that it can move back and forth in a translatory manner parallel to a direction of travel of the strip material.
- the rotating round brush can be arranged to move transversely to the strip running direction (or strip casting direction), whereby it is moved in an oscillating manner (ie back and forth) with an amplitude of 5 to 200 mm and a frequency between 0.005 and 5 Hz.
- the amplitude can preferably also be in the range of 5-100 mm, in which case the frequency can preferably be between 0.01 Hz and 0.5 Hz.
- An electric or hydraulic drive can be provided as an oscillation drive for moving the rotating round brush transversely to the direction of belt travel.
- the setting or selection of the oscillation frequency depends on the condition of the round brush and/or the brush facing selected for this purpose.
- a translational movement of the rotating round brush transversely to the running direction of the strip results in even more intensive abrasive processing on at least one surface of the strip material with which the round brush comes into contact.
- the rotating round brush is also arranged to be translationally movable back and forth parallel to the direction of belt travel or is moved back and forth parallel to the direction of belt travel.
- the round brush can be moved parallel to the direction of belt travel (ie in the direction of belt travel or opposite) while rotating about its axis of rotation, oscillating with an amplitude of 10 to 200 mm and a frequency of between 0.2 and 5 Hz.
- An electric or hydraulic drive can be provided for such a back and forth movement of the rotating round brush.
- a travel speed at which the rotating round brush is moved parallel to the direction of travel of the strip If the rotating round brush is moved translationally in the direction of travel of the strip material and thus "travels along" with the moving strip material, preferably at the same speed as the strip material, this has the advantage that the same point on the strip material while it is in the The belt is moved in the direction of travel, then is processed abrasively by means of the rotating round brush. In other words, the same point on the strip material is abraded by the rotating round brush for a predetermined dwell time, this dwell time corresponding to the time span during which the rotating round brush is moved translationally in the direction of travel of the strip.
- the translatory movement of the round brush in the running direction of the strip preferably has the same speed as the strip material itself.
- the removal of material on the surface of the strip material is intensified and the processing of the strip material can be designed more intensively at the same point by the rotating round brush.
- the rotating round brush is arranged on one side of the strip material, with a support roller in contact with the strip material being arranged on an opposite side of the strip material and aligned with the round brush.
- rotating round brushes are arranged on both sides of the strip material.
- rotating round brushes are arranged on both sides of a strip material, ie on opposite sides thereof.
- both surfaces of the strip material are then processed using the rotating round brushes.
- the round brushes which are provided on the respective opposite sides of the strip material, can be arranged directly one above the other or in alignment with one another, which ensures an optimal flow of forces.
- the round brushes are arranged offset to one another on the opposite sides of the strip material, whereby, for example, the
- a plurality of rotating round brushes can be arranged one behind the other along a direction of travel of the strip material and on the same side thereof.
- a redundancy in terms of process technology is achieved, namely in the sense that the same point on or on a surface of the strip material is repeatedly abrasively processed by a rotating round brush. It is thus possible to rectify any serious surface defects that may be present on a strip surface.
- these round brushes are then each equipped with their own motor drive and their own height adjustment device.
- the respective round brushes can be divided into segments. With a continuous brush roll, areas including bristles alternate with areas without bristles. Depending on the setting/lifting of the round brushes, precise width sections can be set. An even more precise setting of the surface treatment for the strip material is possible if a round brush is segmented in such a way that several shorter individual brush rollers are not only arranged one behind the other in the direction of strip travel, but also across the strip width. Due to the possibility of using the shorter partial brushes individually, a surface defect on the strip material can be corrected with pinpoint accuracy. Equally, a one-time job allows a more precise adjustment to the existing profile of the strip material to be processed.
- a cleaning device is provided adjacent to each rotating round brush and on the same side of the strip material, by means of which a surface of the strip material with which the rotating round brush is in contact can be cleaned.
- compressed air can be generated on the adjacent surface of the strip material and/or negative pressure can be generated adjacent to the surface of the strip material by suction. This ensures that dirt, chips or the like that have been removed from the surface of the strip material by means of the rotating round brush are then effectively removed from the surface of the strip material. This prevents such dirt or the like from being rolled into the surface of the strip material during a subsequent rolling pass.
- the cleaning device uses compressed air directed at the adjacent surface of the strip material, it is desirable that such blowing of the strip surface is carried out transversely to the direction of strip travel, i.e. in the width direction of the strip material. This also ensures that dirt particles or similar impurities lying on the surface of the strip material are removed intensively and without leaving any residue and are therefore not rolled in again in a subsequent hot rolling step.
- the aforementioned cleaning device can have a housing with an entry area and an exit area. It is expedient here if the strip material passes through the housing from the entry area in the direction of the exit area is moved in a direction of tape travel with the housing being shielded from the environment. The interior of the housing is thus suitably shielded from the environment and protected against the ingress of external dirt or the like.
- the housing of the cleaning device can be filled with an inert gas or at least enriched with such an inert gas.
- the aforementioned cleaning device and the rotating round brush are combined to form a structural unit, with the rotating round brush being accommodated in an encapsulated manner within the housing of the cleaning device.
- the interior of the housing can be provided.
- Cleaning device are covered with a negative pressure, whereby air and in particular abrasion and dirt particles, which are caused by the rotating contact of the round brush with at least one surface of the strip material and are contained in the interior, are suitably sucked off and removed.
- air and in particular abrasion and dirt particles which are caused by the rotating contact of the round brush with at least one surface of the strip material and are contained in the interior, are suitably sucked off and removed.
- the above-described encapsulation of the rotating round brush within the housing of the cleaning device serves not only to protect the environment and operating personnel, but also to prevent dirt particles or impurities from re-depositing on a surface of the strip material. Accordingly, this ensures that such dirt particles or impurities are not rolled into the surface(s) of the strip material during a subsequent rolling pass.
- internal cooling can be provided for the rotating round brush. This makes it possible to protect the bristles and the brush body against overheating due to permanent thermal stress.
- a surface inspection device which—seen in the direction of travel of the strip material—is arranged upstream of the rotating round brush and includes a strip tracking system with a defect detection device and a control device.
- the type and location or position of surface defects on the surface of the strip material with which the rotating round brush comes into contact can be detected by means of the flaw detection device, the rotating round brush being controlled by the control device depending on this information(s).
- Such a surface inspection device can be provided both for the device and for the method according to the present invention.
- the round brush can preferably be set or controlled in a controlled manner, namely with regard to its speed, the pressing force against the surface of the strip material, the translational movement transverse to the direction of travel of the strip and/or the translational movement parallel to the direction of travel of the strip.
- the error detection device expediently comprises a tactile sensor and/or an optical sensor or a camera which is aligned with a surface of the strip material.
- the strip tracking system and the associated control device With the help of the strip tracking system and the associated control device, it is possible to allocate the surface defects detected by the defect detection device to an exact point or position on the surface of the strip material, both in relation to a width direction of the strip material and in the direction of its longitudinal extension.
- the operation of the device according to the invention and the implementation of the method according to the invention can be provided such that the brushing intensity is controlled as a function of the measured error (or the measured error), namely taking into account the position of the detected error and/or the size of the error and/or the periodicity of the error.
- the setting parameters of the round brush described above can be used to set the brushing intensity.
- a defect detection device by means of which defects present on or on a surface of the strip material can be detected, as explained, is located on an upper side of the strip material (i.e. above it) and/or on an underside of the Strip material (ie below it) can be arranged.
- a rotating round brush is then arranged on the upper side or lower side of the strip material. If rotating Round brushes are arranged on both sides of the strip material, ie on its top and bottom, for the purpose of cleaning both the top and the bottom of the strip material, these rotating round brushes can be controlled either jointly or individually with regard to their movement parameters.
- the brushes can be made of preferably hardened stainless steel; And or:
- the brushes can be either wavy or straight; And or:

- the material of the casting belt has a high-temperature strength or yield point between 5 and 200 MPa.
- the present invention is suitable for treating the surfaces of non-ferrous metals in order to effectively remove contaminants caused by, for example, a casting release agent. Such a removal or a partial removal of the surface layer of a strip material consisting of a non-ferrous metal takes place before the first rolling pass. This achieves the advantage that impurities are not even rolled into the material during the rolling of a strip material consisting of such non-ferrous metals. In other words, the present invention prevents unwanted impurities resulting from the casting process from being rolled into the material or into the surface(s) of the strip material. As a result, with the aid of the present invention, an improvement in the surface appearance of the finished end products is achieved, for example in relation to the leveling out and gloss of the surfaces.

Provision can be made here for such individual brush rollers 12E not only to be arranged multiple times in the width direction of the strip material B, but also—seen in the direction T of the strip running—in a row.
- FIGS. 1 and 2d show an arrangement of the round brushes in which the axis of rotation is aligned at right angles to the running direction T of the strip. For the sake of completeness, it is pointed out that non-perpendicular orientation is equally covered by the invention.
- FIG. 3 shows a diagram for controlling the device 10 according to the invention or for carrying out a method according to the invention.
- the invention now works as follows:
- the round brush 12 is preset by the control device S with operating parameters such as Speed n, torque Md, contact pressure and oscillating movements operated transversely and/or parallel to the transport direction of the strip material.
- the operating parameters can be adjusted manually or, as will be explained separately below, on the basis of a process model and/or can be adjusted automatically by coupling to a surface inspection device.
- the strip material runs past the surface inspection device 18 before the surface processing.
- surface defects in the strip material B can be detected by the defect detection device(s) of the surface inspection device 18 .
- possible surface defects in the strip material B are detected by measurement.
- these surface defects are evaluated by the belt tracking system of the surface inspection device 18 and the information formed from this is passed on to the control device S.
- the operating parameters for the rotating round brush(es) 12 to be set by means of the control device S, taking into account the measured surface defects, namely with regard to speed n, torque Md, contact pressure and the oscillating Movements transverse (v y ) and/or parallel (v x ) to the belt running direction T.
- a process model it is possible for a process model to be used when setting the operating parameters for the rotating round brush(es) 12 .
- This is symbolized in the diagram in FIG. 3 by a corresponding arrow between the “process mode” and “control device” blocks.
- the required operating parameters for the rotating round brush(es) 12 are calculated using the process model, or alternatively the calculation in the control device S is supported. In any case, as a result, the calculated operating parameters are passed on to the motorized drives or actuators that are assigned to a respective round brush 12 .
- regulation is provided. This regulation takes place depending on the measured surface defects, specifically depending on the position of the defect and/or the size of the defect and/or the periodicity of the defect, with the setting parameters described above using a round brush 12 to adjust the brushing intensity.
- the control device S is equipped with a process computer suitable for this purpose.
- an adaptation calculation is carried out to optimize the control.
- the process computer just mentioned can also be used for this
- part brushes 12 are provided for the device 10 of FIG. 1 , it goes without saying that an individual or separate control is possible for each of these part brushes 12 . If rotating round brushes 12 are arranged on both sides of the strip material B and thus both the top and the underside of the strip material B are cleaned in this way, these round brushes 12, which are arranged above and below the strip material B, can be controlled or regulated either together or individually .
- the specifications for the surface quality from a planning system can be entered into or sent to the control device S, with these specifications then serving as target values.
- the control device S will then suitably take these specifications into account in the calculation of the operating parameters for the rotating round brush(es) 12 .
