Definitions

  • the invention relates to a method for rolling out wire or rolling stock with a round cross-section made of stainless steel or other alloy steel in a high-performance fine steel / wire mill, each with a plurality of roll stands or rolling units, a roughing mill, at least one intermediate mill with a subsequent finishing mill, in particular as a finishing mill block, whereby the finishing roll block is followed by an at least two-stand finishing roll block and, if appropriate, a cooling section and / or a temperature compensation device is arranged between the finish rolling block and the finish rolling block.
  • the invention also relates to a rolling mill for carrying out the rolling process.
  • Modern high-performance fine steel / wire mills usually consist of a roughing mill, one or more intermediate mills and a finishing block for the rolling stock behind the furnace system.
  • the mill stands in the Vorstrasse and Eisenstrasse are robustly built and designed for high rolling demands.
  • Vor No there are generally single scaffolds.
  • In the intermediate line there are preferably compact stands with a horizontal / vertical arrangement of the rollers.
  • a finishing mill is understood to mean rolling machines that consist of several, usually six to ten, alternately offset 90 ° rolling units, which are housed in a cassette in the rolling line and are driven directly and together by a drive via a transfer case.
  • the rolling stock After the finish rolling block, there is a water cooling section with an integrated temperature compensation section for the rolling stock. Depending on the size and quality of the rolling stock, the cooling zones can be controlled so that the required temperature profile in the rolling stock is achieved even at maximum rolling speed.
  • the rolling stock Behind the water cooling section, the rolling stock is air-cooled, for example, on a Stelmor system.
  • a Stelmor system At the end of the Stelmor system there is an adjustable drop step with subsequent chain transport.
  • the wire windings enter the bundle forming chambers via the chain transport.
  • the bundles formed are placed on a hook conveyor via a tipping chair unloading station and from there go into the binding machines and the dispatch.
  • the finishing block be followed by a further, at least two-stand finishing block, with a tempering cooling between the finishing block and the finishing block - And / or compensation device for the rolling stock is interposed.
  • the total pass reduction of existing rolling mills can be increased and thinner finished dimensions can be generated for the rolling stock.
  • the final rolling speed can also be increased if the speed level of the road remains unchanged.
  • the structure in the rolling stock can be influenced by targeted cooling before the last two passes in the roughing block.
  • the object of the present invention is to further develop the rolling mill of the type mentioned at the outset in order to be able to guarantee even the tightest wire tolerances with a high performance level of the mill.
  • the rolling stock is rolled out in the re-rolling block with a significantly lower pass reduction compared to the take-off passes performed in the finishing roll block.
  • the roughing block is therefore used as a precision rolling block in order to improve the surface quality of the rolling stock and to further narrow the rolling stock tolerances.
  • the rolling stock properties and the surface of the rolling stock can be quickly and safely adapted to the respective product requirements.
  • the rolling mill for carrying out the rolling method according to the invention for wire or rolling stock with a round cross-section is characterized in that the post-rolling block has a manual transmission for switching it over to a skin pass or precision rolling block.
  • Manual transmissions in hitherto familiar arrangements of rolling mills to reduce the acceptance ratios may be known per se. However, this has nothing to do with the present measure, since the use of a roughing block behind the finishing block of a rolling mill remained unknown.
  • the switchover of the roughing block or certain framework cassettes of the roughing block proposed here enables the production of the narrowest tolerances of the rolling stock and the adaptation, in particular of existing rolling mills, to a wide range of products.
  • the gearbox can be arranged in front of the roughing block.
  • the gearbox is preferably arranged between the individual stands of the roughing block before its outlet stand.
  • the gear ratio of the manual transmission is designed in a range from 1: 1.25 to 1: 1.15. It is also advantageous if the calibration of the rolls in the finishing block can be adapted to the precision rolling.
  • the invention is described below using an exemplary embodiment for a fine steel / wire mill.
  • This shows: a section of a rolling mill with a finishing mill, a cooling and compensation device and with a switchable finishing mill as a precision mill.
  • the generic fine steel / wire mill generally consists of a preheating chamber in which the pre-block to be rolled out, usually a billet, is preheated before it is heated to rolling temperature in a pusher furnace, for example.
  • the billet comes out of the pusher furnace after descaling the press water into a multi-stand roughing mill, in which the billet cross-section is reduced to a round cross-section.
  • Crank cropping and chopping shears are usually installed after the roughing mill and are able to prepare the cropping end for the intermediate mill.
  • the rolling core passes through the intermediate line, in which the cross section of the round rolled stock is further reduced in several passes. Subsequently, after a renewed cropping of the roll ends, the roll core enters the finishing roll block 1 shown schematically in FIG. 1.
  • the finishing mill 1 has ten swirl-free stand cassettes in a 45 ° arrangement.
  • the horizontal stand cassettes 16 are drawn perpendicular to the rolling core 5 in the schematic plan view and drawn out with a reinforced line.
  • the vertical stand cassettes 17 are shown as opposing rolling rings.
  • the finishing mill block 1 is connected to a transfer case 2, from which an output shaft 3 is laid to the horizontal stand cassettes and an output shaft 4 to the vertical stand cassettes.
  • the section of the fine steel / wire mill shown also shows a two-stand roughing block 6, the vertical stand cassette 6 'and the horizontal stand cassette 6' 'being arranged at a 90 ° angle to one another.
  • the finishing mill 1 and the finishing mill 6 are aligned with each other in the rolling line.
  • the roughing block 6 is connected to a manual transmission 7, from which an output shaft 8 is guided to the horizontal stand cassette and an output shaft 9 to the vertical stand cassette.
  • the input shafts 10, 11 of the transfer case 2 or of the manual transmission 7 are directly coupled to three DC motors 12 of the same power rating. The DC motors are used to drive the finishing block and the finishing block.
  • a water box 13 for cooling the rolling stock and a compensation section 14 for temperature compensation of the rolling stock are provided between the transfer case 2 and the manual transmission 7.
  • the roughing block 6 has a changeover gear 15 between the vertical stand cassette 6 'and the horizontal stand cassette 6''in order to be able to use the roughing block as a precision rolling stand if required.
  • the gear ratio of the changeover gear 15 is approximately 1: 1.25 to 1: 1.15. If the roughing block is used as a precision roll stand, the calibration of the rolls of the discharge stand or the stand cassette 6 ′′ is adapted to the specified precision roll.
  • a further water cooling section is optionally arranged, which was not shown in more detail, as well as a Stelmor system, a bundle forming chamber and a hook track for the cooled wire bundles that were prepared for dispatch.
  • the wire is then passed through the water tank 13, cooled in it and then passed through the temperature compensation section 14.
  • the temperature cooling and temperature compensation are controlled depending on the respective wire alloy and the desired quality profile. If necessary, a cooling / compensating arrangement of the finishing block 1 can be switched on.
  • the wire then enters the roughing block 6 and is rolled out in the first vertical stand cassette in a standard pass to initially 5 mm in diameter.
  • the rolling mill of the type specified here is made even more adaptable to the different rolled product products and rolled material qualities by switching the post-rolling block into a precision rolling stand according to the invention.
