Definitions

  • the invention relates to a method for hot rolling seamless tubes with one or more consecutively arranged longitudinal or Schrägwalzgerüsten and an inner tool used in the interior of the rolling stock in the form of a mandrel or roll bar, as by the DE 21 31 713 A1 known.
  • the inner tools / mandrel rods in the forming of seamless tubes are subject to high mechanical and thermal stresses depending on the manufacturing process. Accordingly, a high wear of the tool surface occurs, which leads to abrasion, adhesion and disintegration and with relatively little service life to surface damage to the forming material and the failure of the tool. Therefore, an attempt is made to use as hard, wear-resistant materials in the heavily loaded tool areas.
  • Ceramics, cermets and other highly wear-resistant materials have the properties, which are particularly disadvantageous for this purpose, of low thermal shock resistance, low bending strength and high sensitivity to cracking when tensile stresses occur.
  • the invention is therefore an object of the invention to provide a generic method and a generic inner tool that allow seamless tube production without the disadvantages described in the use of special materials for the inner tool.
  • the occurrence of tensile stresses is avoided by distributed around the circumference tool inserts are used with which tool parts, eg. B. segments of highly wear-resistant material, are biased under high tangential compressive stresses.
  • tool parts eg. B. segments of highly wear-resistant material
  • a stress state with high compressive stresses is generated which, when loaded by the rolling stock, leads to a three-dimensional compressive stress state and thereby makes it possible to avoid the occurrence of tensile stresses.
  • This enables the use of wear-resistant but brittle materials on the internal tools in rolling mills of seamless tube production.
  • the number of tool parts or segments depends on the number of rollers, so that the mandrel / roll bar, d. H. the inner tool may have two, three or more segments, each with gapless tool inserts therebetween.
  • the workpiece inserts are arranged so that they are in the load case in the area without Walzguttive or in the range of only low mechanical and thermal stress.
  • the inner tool is aligned so that the workpiece inserts are positioned in the areas between the rollers.
  • the rolling rod or the inner tool should likewise be positioned and not rotate.
  • the tool body is provided with a central longitudinal bore and with radial, oblique Zu Industriesbohrungen through which the medium is conveyed under pressure and adhering to the inner surface of the tube to the contact zone.
  • each roll stand is supplied with the medium in this way. Even with skew rolling plants, the supply takes place in the same way.
  • the perforated, tubular rolling stock 3 is rolled out between successive rolls 4 of the Kontiwalzstrom 1 on an inner tool 5, designed as rolling or mandrel, the Kontiwalzstrom 1 can be advantageously operated with held inner tool 5, so that the feed path between minus 1 stand spacing to plus 1 stand distance.
  • the inner tool 5 consists of a central longitudinal bore 6 having a base body 7 and arranged thereon tool segments 8 of a highly wear-resistant, heat-resistant material and between them provided, as indicated by arrow 9 (see. Fig. 2 ) radially engageable tool inserts 10.
  • the tool segments 8 and inserts 10 are taken up by a sleeve 11 enclosing the base body 7.
  • the tool segments 8 and inserts 10 are axially biased, as in FIG Fig. 1 indicated by the arrows 12. Since the tool segments 8 by the Radialan beaukeit (arrows 9 in Fig. 2 ) of the tool inserts 10 at the same time a tangential pressure or bias according to the in Fig. 2 registered double arrows 13, no tensile stress occurs in the tool segments 8, which is very important especially in brittle material, such as ceramic, the tool segments 8. During rolling, an all-round compressive stress is achieved. For better effectiveness when introducing the tangential and axial compressive stresses on the one hand, the sleeve 11 with the Tool segments 8 and - inserts 10 and on the other hand, the tool inserts 10 with the tool segments 8 with wedge surfaces 14 to each other.
  • a plurality of feed bores 15 are provided radially, obliquely formed.
  • An introduced into the longitudinal bore 6 from a supply source, not shown cooling, lubricating and separating agent is introduced via the supply holes 15 under pressure directly into the contact zone between the rolling stock 3 and the inner tool 5. There it comes to the desired adhesion to the inner circumferential surface of the rolling stock.
