Definitions

  • the invention relates to a method and a rolling mill for the production of Wire, rods or seamless tubes on a rolling mill for rolling heated Metallic material, including optionally seen in the rolling direction Piercing mill, a multi-stand stretch rolling mill as the main drawing stage, a pull-out rolling mill, a finishing mill and a wire rod block, as well as or downstream equipment such as a pre-heater and a reheating furnace, Roller tables, separators and a cooling bed.
  • the invention is therefore based on the object, a rolling process and a To create rolling mill of the type mentioned, the optimized operation allow with further reduced investment.
  • the solid line separated from the tube rolling line is arranged, according to the invention can be a single line for both purposes use, which not only the investment costs are much lower, but also the operating and maintenance costs.
  • This is the consistent exhaustion based on the 3-roll technology, because it was recognized that despite each other conflicting requirements - when pipe rolling is used to avoid of procedural disadvantages of the outer diameter usually little changed and the high elongation arises due to the central hole, while Massive rolling ensures a large diameter reduction must, in order to achieve the required extension - a universal rolling possible is.
  • An advantageous embodiment of the method according to the invention provides that also for the main drawing stage upstream piercing mill, a 3-roll cross rolling mill is used, whose perforated rollers for solid rolling with remote Punch bar against provided bar steel rollers with for a diameter reduction calibrated rollers are replaced. That at a piercing mill 3-roll cross rolling mill according to the invention then allows at Solid rolls weg complexer Lochdomstange the production of different Bar diameters in the sense of prereduction, i. one on the total reduction All operated rolling mills related proportionate cross-sectional reduction.
  • the perforated tube rolling mill thus fulfills a universal function.
  • a rolling mill for carrying out the method according to the invention in the Kleinstreckcut a trained for receiving bar steel rolls or pipe rolls, multi-stand 3-roller continuous rolling mill and a device for removal the mandrel on.
  • the Kontiwalzwerk or the main drawing stage takes in a framework either one or the other stands or sets of rolls, each consisting of three rollers, on.
  • corresponding scaffolds are provided, which are then withdrawn the previous scaffolding from the frame in the operating position become.
  • a cassette construction or replacement only the rolling possible with remaining in the frame scaffold housings.
  • the Mandrel can be during the conversion of the 3-Walzen-Kontiwalzwerkes for Solid rollers in the simplest case with the aid of the mandrel bar holding device drive to an inoperative position.
  • This also applies to the piercer bar of the main draw step in the case of Rohrwalzung optionally upstream Schrägwalztechnikes, which according to an embodiment of the invention also as a universally applicable 3-roll cross-rolling mill is formed.
  • a preferred embodiment of the invention provides that the 3-roll continuous rolling mill the main stretching stage is assigned a speed control.
  • the different rolling speeds during tube and bar rolling can be achieved realize.
  • the arranged behind the main expander extracting two spaced framework units with one in between insertable provided end scissors can be during solid rolling Cut off bad ends in a simple manner before further rolling.
  • pipe rolling can be dispensed with the use of the scissors.
  • the Ausziehwalzwerk connects advantageously to a reheating furnace. From there then the heat treated bar or e.g. alloyed or unalloyed Steel pipes in the finishing mill.
  • This can be a sizing mill, a reduction mill or a stretch-reducing mill or a combination of these aggregates include.
  • the cooling bed arranged a leading to the wire block roller table.
  • the universal rolling mill shown in the plant scheme processed in one Line i. deviating from the graphic representation is closed in the lower half of the piece of equipment shown linear to the system parts of the upper Drawing half, which is indicated by the meandering line, a fed Starting material (insert block) either to seamless tubes or rods, Wire or similar solid rolling stock.
  • the blocks are heated to rolling temperature.
  • a heated insert block designed as a 3-roll cross rolling mill 3 Passed hole punching mill where the block is guided in an inlet chute and by rolling on a mandrel bar provided with a mandrel to a Hollow block in preparation for the subsequent rolling out to a seamless tube is deformed.
  • Such a cross rolling mill 3 in Dreiwalzenbauweise is known in the manufacture of pipes. If not pipes, but Rods or wire to be rolled, takes place in the 3-roll cross-rolling mill 3 with retained or brought out of the rolling line perforated mandrel bar Massively reducing the block and compacting the texture instead.
  • An outlet side of the measure or stretch reducing mill 10 arranged Schopfsäge 12 divides the finished tube or the finished rolled bar steel in the desired lengths.
  • the finished lengths are then transferred to a cooling bed 13. If, on the other hand, the bar steel is to be rolled into wire, the bar steel becomes fed via an extension of the cooling control gear 14 a wire block 15.
  • the universal rolling mill described thus allows both in one line to roll seamless pipes as well as rods or wire. This will be the case Solid rollers in the 6-stand 3-roller continuous rolling 5 previously with a Calibration for tube rolling designed rolls against for a massive rolling replaced calibrated rollers and the mandrel in an inoperative position brought, e.g. by the mandrel bar holding device in its retracted Starting position is driven.
