Definitions

  • the invention relates to a cleaning device and a method for removing a lubricant from the rolls of a roll stand See, for example DE 101 48 401 A ,
  • Roll stands especially in hot strip mills, typically include nip lubrication equipment, usually mounted to the upstream side of the mill in the area of the work roll.
  • a lubricant is applied to the work roll, as a lubricant usually a water-oil emulsion is sprayed.
  • the lubricant significantly reduces the coefficient of friction between the respective roller and the rolling stock. This reduces the rolling forces and the surface quality of the rolling stock is improved. As a result, few rolling steps are required and / or the profile and the flatness of the rolling stock can be better influenced by a greater degree of freedom in the rolling force. In addition, energy consumption is reduced and the production spectrum increased.
  • the rolls Before tapping the rolling stock, which is for example a rolled strip, however, the rolls, in particular the work rolls, must be free of lubricant in order to increase the coefficient of friction of the roll again, otherwise there is the risk that the rolling stock will not be drawn into the roll stand, which leads to an interruption of the rolling process. For this reason, the roll gap lubrication is switched off just before unloading the rolling stock, thereby burns the lubricant due to the high belt temperature completely in the remaining Walzenumassin. Only after renewed threading of the next rolling stock, the roll gap lubrication is switched on again. The head and foot of the rolling stock are therefore rolled ungeschmiert. This, however, adversely affects the Rolling, since the foot of the rolling stock, which is usually the coldest, requires the highest rolling force.
  • WO 2006/089730 A1 a method for cleaning a metal strip is known in which the metal strip is subjected to ultrasonic cleaning in which the metal strip is passed through a container filled with a liquid.
  • the invention has for its object to increase the efficiency in the cleaning of the rolls of the mill stand, without increasing the water consumption for cooling the rollers during operation of a roll stand substantially.
  • the object is achieved by a cleaning device with the features of claim 1.
  • the object is also achieved according to the invention by a method solved with the features of claim 9.
  • the invention is based on the finding that the pressure of the cleaning liquid can be reduced, but still there is an intensive surface cleaning with a high efficiency by the cleaning is supplemented by ultrasonic waves, which propagate with the cleaning liquid to the surface of the roller and increase the cleaning effect .
  • Ultrasound is known to work even in small wells of the surface and mechanically bring adhering particles or substances into solution. Thanks to the ultrasonic waves, the risk of damage to the surface of the roller is minimized.
  • notches on the surface of the roller, such as fire cracks can be cleaned efficiently.
  • the cleaning liquid is applied in particular to the roll surface at a pressure of 5 to 15 bar, the pressure being about ten times lower than the required pressure according to FIG JP 2002-178011-A ,
  • the at least one ultrasonic generator is integrated in particular in the cleaning device, and surrounded by the cleaning liquid, so that the ultrasonic waves are delivered directly to the cleaning liquid and forwarded with this.
  • the result is a fluid bridge between the ultrasonic generator and the roller surface, which transmits the sound waves.
  • This type of cleaning can be applied to both the work rolls and the back-up rolls of a rolling stand.
  • water is used as the cleaning agent. Since water is chemically neutral, the use of water is gentle on the rollers. In addition, water is anyway a wide application in the rolling process, so that in a rolling mill large amounts of water are available.
  • the main advantage of such a cleaning is that the lubrication can be used for the whole band foot and for the essential part of the band head. This reduces the rolling force, resulting in a significant energy saving effect.
  • the product range is broadened: with an identical design of the system (drives, hydraulics and stands), harder steel products can be rolled.
  • a particularly good synergistic effect which increases the efficiency of cleaning, is achieved by branching off the cleaning water from the cooling water circuit for the rolling mill, the water being supplied via a supply line to the cleaning device and this supply line being a branch of the cooling water circuit for the roll.
  • the water consumption for the rolling stand can be kept constant during the cleaning phase, there is only a redistribution of the water by a portion of the cooling water of the cleaning device is supplied. This results in the advantage that the roller temperature increases somewhat, so that the cleaning performance is supported by the higher roller temperature at which the lubricant dissolves better from the roller surface.
  • the ultrasonic generator for generating ultrasonic waves having a frequency between 20 kHz and 2 MHz, in particular between 35 kHz and 200 kHz, set.
  • This frequency range has proved to be particularly advantageous for the ultrasonic cleaning of fine dirt.
  • at least two ultrasonic generators of different frequency are provided, e.g. an ultrasonic generator with 40 kHz and an ultrasonic generator with 80 kHz frequency.
  • a sealing element which faces a nip between the rollers is, so that the sealing element seals the roller against an outflowing liquid in the direction of rotation of the roller.
  • an opening facing away from the roll gap is provided on the cleaning device, through which the cleaning water is conveyed to the surface of the roller.
  • the cleaning device is arranged at least upstream of the respective roller.
  • cleaning devices can also be provided on the outlet side. Since the cleaning device is characterized by a manageable number of additional components, it requires a small installation space and can be easily installed in a protected installation position in existing components of the mill stand.
  • the cleaning device is integrated in particular in a chock of the work rolls or in a chilled beam for the rolling stand.
  • at least one inlet side arranged cleaning device is provided in reversibly operated rolling stands are two cleaning devices per roll useful - an inlet and an outlet side.
  • the cleaning water contains an emulsifier.
  • the cleaning performance is increased because lubricant particles thrown up during the cleaning process do not settle again so easily on the roll surface can.
  • the same emulsifier is used, which is admixed with the lubricant. In this way, it is ensured that no additional resources must be made available, but the cleaning of the roll surface is carried out only with the help of resources that are required and permitted anyway for the operation of the rolling mill.
  • the temperature of the cleaning water is between 0 ° C and 70 ° C.
  • the temperature of the cleaning water corresponds to an ambient temperature, so that no additional heating effort for the cleaning water is required, or such a heating effort is limited.
  • the cleaning device is preferably active only between a tapping of a preceding rolling stock by means of the roll stand and a tapping of a subsequent rolling stock.
  • a tapping of a preceding rolling stock by means of the roll stand and a tapping of a subsequent rolling stock.
  • the cleaning process is interrupted and normal operation of the rolling mill resumed.

  • a lubricant is supplied to the work rolls 4 through lubricant nozzles 14.
  • the nip 8 must be free of lubricant, so that the rolled strip 12 can be easily drawn into the rolling stand 2.
  • a cleaning device 16 per drive roller 4 per a cleaning device 16 is provided with the aid of a cleaning liquid, in the illustrated embodiment, water is applied to the surfaces of the work rolls 4. The cleaning water is applied only to a part of the surface. By rotating the work rolls 4, however, the effective range of the cleaning water shifts around the circumference of the respective work roll 4, so that ultimately the entire surface area of the work rolls 4 is exposed to the cleaning water.

  • a sealing element 32 which is formed in the manner of a sealing lip arranged. In particular, by its contact with the roll surface, the sealing element prevents water from the cleaning device 16 during the rotational movement of the work roll 4 down to the rolled strip 10, 12, flows.
  • an opening 36 is formed through which the water is passed from the cleaning device 16 in the opposite direction to the direction of rotation of the work roll 4 to the roll surface.
  • the lower roller 4 shows the opening 36 down, so that additionally acts gravity and amplifies the flow of cleaning water.
  • openings 36 facing away from the roll gap 8 openings which are not shown here in detail can also be provided in the region of the front sides of the work rolls 4. In this case, the lateral Outflow of the cleaning water, for example, collected via lines or baffles and can be recycled.
  • baffles 38 are provided in the cleaning device 16, which cause a uniform flow through the cavity 38, so that the formation of dead zones in the cavity 28 is suppressed.
