Definitions

  • the invention relates to a method for working up Rollers for the production of rolling mill products, at which the roller after use by processing the Roll surface is worked up.
  • rolls for the production of rolling mill products one to the roller surface adapted to the respective application exhibit.
  • work rolls face the warm or Cold rolling metal strips on a roll surface with a defined roughness to ensure a safe Gripping the rolling stock through the rollers and the Production of a defined surface of the rolling stock guarantee.
  • Other types of rollers such as for example back-up rolls, strip drawing rolls or The like have a defined roll surface, which the proper functioning of these rollers guaranteed.
  • the filling of the ground structure of the roller surface leads to various effects. For one, there is one safe gripping of the rolling stock by the rollers more secured and the rollers begin to slide. Also accumulate in some places on the roller surface of the Work rolls reinforce the above particles and lead to unwanted impressions on the rolled Strip surface. Sometimes they also come off accumulated and compacted particles in larger Units and remain on the surface of the tapes as a so-called pickup.
  • rollers are expensive to manufacture Products, these are, as from the state of the Known technique after the formation of a rolled shirt or The like is not completely replaced but expanded and worked up by machining the rolling surface. After working up, the rollers point to theirs The desired properties and can continue to be used. From the state of the It is known in the art to recondition the rolls that the roller surface with mechanically abrasive Processes, such as grinding, is processed. This process removes from the roll surface defines the deposited impurities and that Material taken from the roller itself to a to produce unused roll surface. Partially are the roller surfaces after the mechanical abrasive treatment even with a new coating or subjected to hardening.
  • the machining of the roller surface can be done with Using a jet of liquid much faster take place as the processing of the roller surface with mechanically abrasive processes such as grinding.
  • the method according to the invention can also be used with the mechanically abrasive known from the prior art Combine procedures.
  • liquid pressure during the generation of the liquid jet is set to approximately 20 to 250 MPa (10 6 Pa), preferably 50 to 250 MPa, more preferably 100 to 250, ensures that the residues and contaminants on the rollers are reliably detached.
  • mechanically driven piston pumps plurize such pressures, in some cases with the additional use of hydraulic pressure intensifiers.
  • Fig. 1 Section shows the profile of a work roll Hot rolling mill for aluminum alloys. Similar Cuts through rollers adapted for other purposes would in principle reflect similar constellations.
  • the actual roller material 1 shown hatched. in the The present case is a steel roller.
  • the Contoured roller surface in the scale shown and a plurality of elevations 2 and depressions 3rd having.
  • Elevations 2 and depressions 3 generally as Called roughness guarantee when using the work roll shown, as already mentioned, among other things, a reliable gripping of the rolling stock through the rollers and a desired one Surface shaping of the rolled stock. This is done by the between the elevations 2 and the depressions 3 and Rolled aluminum strip resulting friction guaranteed.
  • the roller surface shown in Fig. 1 belongs to a roller that is already used to a significant extent has been.
  • Hot rolling of aluminum strips in the recesses 3 Aluminum oxide and aluminum particles accumulated, the compressed to deposits 5 by the high rolling pressure have been.
  • the in Fig. 1 deposition 5 already a part of the elevations 2, whereby the handle between the Roll surface and the rolling stock is reduced. hereby there are increasing effects such as slipping Rolling, the detachment of deposits 5 on the The surface of the rolling stock remains and becomes stronger at certain points Accumulations of deposits 5 on the Leave marks on the surface of the rolling stock.
  • the roller surface shown in Fig. 1 must Production of flawless rolling stock be worked up.
  • the process is carried out in that the Roller surface with the help of a liquid jet, such as shown in Fig. 2 is edited.
  • a liquid jet such as shown in Fig. 2 is edited.
  • water is preferably used as the liquid, since at Hot rolling itself a water / oil emulsion is used the water is therefore not a foreign substance in the process.
  • a roller 6 shown in Fig. 2 has a certain use one of those shown in Fig. 1 Deposits 5 existing roll shirt 6, which at the processing must be removed.
  • the workup according to the invention shown in FIG. 2 can be installed as well as removed Condition of the roller 6 take place.
  • the Beam lance 10 can be guided by hand or automatically. It is advisable to have one inside the roll stand Arrange device that the jet lance at Refurbishment of the roller 6 automatically, defined by the Roll surface 8 leads to the rolled shirt - as soon as this is necessary - to remove.
  • Processing was carried out in the described processing a water jet with a pressure of about 200 MPa without the addition of particles used.
  • one Work roll for hot rolling aluminum has shown that the roller after multiple work-up with Conventional using the method according to the invention, i.e. through mechanically abrasive processes such as grinding and subsequent chrome plating should be basic to the roller surface work up.
  • This conventional workup is at about the described embodiment two reprocessing according to the invention required.
