Definitions
- the invention relates to a method for applying a controllable tension distribution, in particular in the edge areas during cold rolling of metal strips, in order to reduce the risk of excessive tensile build-up and strip edge cracks with the disadvantageous consequence of production-reducing strip cracks, and to improve the strip surface and its flatness even at relatively higher levels Belt travel speed and to reduce belt trimming widths.
- the invention also relates to an apparatus for performing the method.
- a method is known from document EP 0 054 172 A2 in which the friction coefficient between the strip surfaces and the roll surface of the roll surface is influenced by the application of rolling lubricant for the tension-free rolling of cold strip. This is applied as a function of the partial tensile stresses determined behind the last frame in the transverse direction of the belt.
- Base oil is applied to the rolling lubricant directly on the strip surfaces in quantities determined by the partial tensile stresses determined and in localized areas before the strip enters the roll gap.
- the aim of this measure is to apply the lubricating components locally to strips of the strip to be rolled in order to reduce the rolling force there due to the locally improved lubrication and thus also to reduce the local flattening of the roll. Furthermore, the frictional heat introduced into the roller is reduced at these points.
- a method and a device are known from document EP 0 367 967 B1 in which the concentration of an emulsion of rolling oil is influenced in a targeted manner and the emulsion or dispersion after it has left the roll gap or Drain in front of the roll gap and is separated again.
- This makes it possible to produce the emulsion or dispersion that is introduced into the roll gap again and again with a certain concentration in good time before it is drawn into the roll gap.
- the focus of this invention lies in the current production of the emulsion and the separation of the media involved.
- Document EP 1 188 494 A1 describes a strip wiping device, strip wiping method, roll stand and rolling process. To improve the productivity of a cold rolling device, this was provided with a belt scraper.
- Document EP 0 672 471 B1 discloses a method and an apparatus for rolling strips.
- Low-wear rollers with rollers with enlarged radii in at least one of their end regions are displaced relative to one another in such a way that the width of the rolled strip is in contact with regions of the smaller radius, and that with increasing heating and with thermal crowning by displacement in opposite directions areas of their larger radius are pushed over edge areas of the rolled strip. It is thereby achieved that the edge region excesses of the band, which would occur due to the increasing thermal crowning, are eliminated.
- Document DE 199 08 743 A1 discloses a method and a device for drying and keeping dry, in particular, cold strip in the outlet area of cold rolling and strip systems.
- a contactless seal between the partition and the band is proposed by means of an air cushion-like compressed gas cushion and a gap flow in order to apply compressed gas from a large number of blowing nozzles from blowing nozzle strips to the band surfaces at right angles from above and below.
- Document DE 101 31 369 A1 discloses a method and a device for cooling and / or lubricating rolls, in particular the work rolls of a roll stand and a rolled strip rolled and conveyed between these rolls, using water in the form of spray jets as cooling medium and spray oil, Oil-air mixture or oil-water mixture, as a lubricant.
- a combined use of subcooling of the strip and roller surface and roller lubrication on the scraper inlet side is proposed, in that the two media - water and lubricant - are fed separately to the rollers or the rolled strip and to different roller application points - Surface to be applied.
- the invention in cold rolling, in particular in the aluminum industry, but in some cases also in the steel and non-ferrous metal sector, is based on the task of minimizing the tight strip edges and long strip fibers that occur near the edges and reducing strip tears To save trimmings and thereby improve the quality and quantity of the application.
- the risk of tape breakage due to tape edge tears is demonstrably reduced and the tape surface is additionally improved.
- An embodiment of the method according to claim 1 provides that an increased decrease in diameter of the work rolls at the edge region as a result of partial increase in diameter during their shaping is carried out by means of inductive heating.
- a device for applying a controllable tension distribution, in particular in edge areas when cold rolling metal strips preferably for carrying out the method according to the invention, is characterized by spray nozzle arrangements in at least two separate zones with connections to separate spraying agent feeds to different zones of each work roll and / or by one Special sanding with increased diameter at the end areas of work rolls for the purpose of lengthening the strip edges to be rolled while simultaneously reducing tensile stresses and reducing long strip fibers in areas of the strip edges near the edges.
- a further embodiment of the device advantageously includes a swivel castor which is convexly bendable or curved in the strip running direction in an arrangement between two guide rollers for changing the tension distribution of a strip before it enters a roll stand.
- the device is also designed in such a way that it has means for direct additive application, in particular onto the rolled strip, for example, on the inlet side of a roll stand.
- B. for lubricating oil with a relatively high viscosity and on the outlet side of the work rolls means for bale cooling of the work rolls and preferably additional means for lubricant removal, which preferably spray the rolled strip from both the top and the underside of the strip with the assignable spray media.
- the device according to the invention has a device which removes coolant in the outlet side of the frame.
- Figure 1 shows a device for "hot edge spray" on the roller edge
- Figure 2 shows a special grinding for work rolls
- Figure 4 The top view of the swivel castor acc. Fig. 3
- FIG. 5 A side view of a system according to the invention with direct application of lubricant to the rolled strip, roller cooling on the outlet side and removal of lubricant.
- FIG. 1 shows part of a device for applying a controllable tension distribution, in particular in edge areas during cold rolling of metal strips, with spray nozzle arrangements 11, 11 'present in at least two separate zones 10, 10' with connections to separate spray agent feeds 19, 19 'to different zones 10 , 10 'of each work roll 12.
- spray nozzle arrangements 11, 11 ' present in at least two separate zones 10, 10' with connections to separate spray agent feeds 19, 19 'to different zones 10 , 10 'of each work roll 12.
- FIG. 2 shows a pair of work rolls 12, 12 ', each of which has a special grinding 13, 13' in one end area with enlarged diameters in the end areas in order to lengthen the strip edges to be rolled while simultaneously reducing tensile stresses and reducing long strip fibers.
- Figure 5 shows a side view of a system according to the invention, with a decoiler on the left side and a decoiler on the right side as well as guide means for the rolled strip 16 in the strip running direction 14 and means 21 for direct application of lubricant with viscosity or additive on the strip entry side and Means 22 for cooling the bale of the work rolls on the outlet side and with means 23 for removing lubricant on the outlet side.
- a material build-up on the belt edge during the preliminary stitches and, accordingly, a material breakdown on the belt edge during the finish stitches is achieved with the aid of an additive direct application on the inlet side and roller cooling on the outlet side.
