Definitions

  • the invention relates to a process for the processing of Rolling of a hot rolling mill for aluminum materials for the production of rolling mill products, in which the roller after or during use Processing the roll surface is worked up, (see e.g. DE-A-19848174).
  • rolls for the production of rolling mill products to the Customized roller surface adapted exhibit.
  • work rolls have warm or Cold rolling of metal strips a roll surface with a defined roughness on to a safe Grasping the rolling stock through the rollers and the Production of a defined surface of the rolling stock guarantee.
  • other types of rollers like For example, backup rolls, Bandzugwalzen or the like have a defined roll surface, the perfect function of these rollers guaranteed.
  • the at Hot rolling of aluminum strips used Work rolls have a surface on their surface
  • the production structure desired surface properties of the rolling stock guaranteed and on the other hand for secure gripping the Rolled material contributes through the rollers, causing a slip is avoided in the nip.
  • the rollers Alumina or aluminum particles or - depending on rolled alloy - magnesia or Magnesium particles from. These particles are in the Recesses by the high roller pressure force such they compacted the depressions of the cut structure compact and very resistant filling. This In turn, this leads to a sharpening structure at the Roll surface after a certain period of use of Roller is no longer effective during rolling.
  • the on the Roll surface formed deposits are called also as a rolling shirt.
  • the filling of the ground structure of the roll surface leads to different effects. For one thing is one secure gripping of the rolling stock by the rollers not more secured and the rollers start to slip. Also collect at some points of the roll surface of the Work rolls reinforce the above particles and lead to unwanted impressions on the rolled Strip surface. Partly solve the accumulated and compacted particles in larger Units and remain on the surface of the tapes as a so-called pickup.
  • rolls Products Since it is costly to manufacture rolls Products, these are, as from the state of Technique known after the formation of a rolling shirt or The like not completely replaced but expanded and worked up by working the rolling surface. After working up, the rollers have their Roll surface again on the desired properties and can continue to be used. From the state of Technique it is known to work up the rolls thereby that the roll surface with mechanically abrasive Process, such as grinding, is processed. In this process are from the roll surface defines the deposited impurities and the Material of the roller itself taken off to a produce unused roller surface. Partially the roll surfaces after the mechanical abrasive treatment also a re-coating or curing.
  • mechanically abrasive Process such as grinding
  • the present invention Based on the previously described prior art and the related problems is the present invention, the object of a Process for working up rolls for the production of rolled products, which is a simple, fast and cost-effective processing of the rolls guaranteed.
  • the previously derived and shown task solved by the Roll surface by means of a liquid jet is processed and the fluid pressure at generation the liquid jet to about 50 to 250 MPa, preferably 70 to 150 MPa, is set.
  • liquid pressure in the generation of the liquid jet according to the invention to about 50 to 250 MPa (10 6 Pa), preferably 70 to 150 MPa, is set, a secure detachment of the residues and contamination on the rolls is guaranteed.
  • mechanically driven piston pumps pluripotent pumps
  • hydraulic pressure booster for the production of such pressures mechanically driven piston pumps (plunger pumps) are used in the majority of cases partly with the additional use of hydraulic pressure booster.
  • a first advantageous embodiment undergoes the inventive method in that the Roll surface for workup exclusively with Help a liquid jet is processed. It has It turned out that the editing of the Roll surface by means of a liquid jet to Reprocessing of rolls is so thorough that a further processing of the roll surface especially unnecessary by brushing. In particular, stay usually also coatings of the roll surface, For example, to increase the strength of Roll surface have been applied, usually when processing with the help of a liquid jet receive.
  • FIG. 1 greatly enlarged Section shows the profile of a work roll one Hot rolling mill for aluminum alloys.
  • Fig. 1 In the section shown in Fig. 1 is the actual roll material 1 shown hatched. in the The present case is a steel roller. For other applications come e.g. also rolls of cast iron for use. It is clear that the Roll surface contoured in the scale shown is and a variety of surveys 2 and wells 3 having. These provided in the roll material 1 Elevations 2 and 3 wells, generally as Roughness designated, ensure during use the illustrated work roll, as already mentioned, among other things a reliable gripping of the rolling stock through the rollers and a desired one Surface shaping of the rolling stock. This is done by the between the elevations 2 and the wells 3 and the rolled aluminum strip resulting frictional engagement guaranteed.
  • Fig. 1 is further shown that on the Roll surface has been made a chrome plating 4 is.
  • This full-surface chrome 4 serves to increase the hardness of the roll surface and thus the Stability of the surveys 2.
  • the roll surface shown in Fig. 1 belongs to a roller that is already in use to a considerable extent has been.
  • the Hot rolling of aluminum strips in the recesses 3 Aluminum oxide and aluminum particles accumulated, the compressed by the high rolling pressure to deposits 5 have been.
  • the cover in Fig. 1 shown deposits 5 already a part of the elevations 2, whereby the grip between the Roll surface and the rolling stock is reduced. hereby Increasingly, there are effects such as slipping Rolling, the detachment of deposits 5, on the Walzgutoberfiguration remain and stronger to selectively Accumulations of deposits 5 on the Walzgutober Structure leave impressions.
  • the roll surface shown in Fig. 1 must for Production of further perfect rolling stock be worked up.
  • the work-up is done by the Roll surface by means of a liquid jet, such as shown in Fig. 2, is processed.
  • a Work roll of a hot rolling mill for aluminum is as liquid preferably used water, as at Hot rolling itself a water / oil emulsion is used the water is therefore not foreign in the process.
  • a roller 6 shown in Fig. 2 has a certain use one of those shown in Fig. 1 Deposits 5 existing rolling shirt 7, which at the workup must be removed.
  • the process according to the invention is carried out Work-up characterized in that the roll surface 8 with Help a liquid jet 9, which consists of a Blasting lance 10 emerges, is processed. In that already processed by means of the liquid jet 9 Surface area 11, the rolling shirt has been removed.
  • the work-up according to the invention shown in FIG can be used both in built-in and removed Condition of the roller 6 done.
  • the Blasting lance 10 can be guided by hand or automatically. It makes sense, within the rolling stand a To arrange device that the jet lance 10 in the Processing of the roller 6 automatically defined over the Roller surface 8 leads to the rolling shirt - as soon as this necessary - to remove. This is also during the Rolling process possible.
