Definitions

  • the invention relates to a device for producing pipes with a special property profile with a device for coolant treatment of a pipe surface.
  • the properties of the material of the tube wall can have significant differences locally and los related. These property differences are usually based on an uneven microstructure and on an unfavorable steel composition or an increased proportion of accompanying and impurity elements.
  • Tubes with a length of 7 m and larger and an outer diameter of less than 200 mm with a wall thickness of less than 25 mm can be subject to a heat treatment only with great effort, which provides a uniformly fine structure with the desired structure over the entire tube volume and bending perpendicular minimized to the longitudinal direction.
  • the WO 98/38345 discloses a method and apparatus for producing welded tubing in which rolled sheet having contents of C, Mn, Ni, Nb, Ti and N is subjected to a double-sided heat treatment, rolled up in the longitudinal direction by multi-layer welding Tube is formed.
  • the JP 54037011 A discloses a switchable continuous hardening plant for pipes with an outer coolant supply part and of this inwardly directed, in the passage direction of the pipe inclined concentric nozzles or coolant supplies, which can be interrupted by shading.
  • a particular embodiment of a spray cooling system of cooling rings discloses the US 2007/181234 A1 , wherein the cooling rings can be positioned independently of each other.
  • a flat circular Sprühstoffstrom each cooling ring is directed from a coaxial annular gap in the direction of passage of the material to be cooled obliquely-axially on this, in each case the next front cooling ring has a beam protection for the flat beam reflected by the refrigerated goods.
  • the object of the invention to provide an apparatus for producing tubes made of steel with increased strength and improved toughness of the material by rapid cooling after deformation, consisting of a device for coolant loading a pipe surface, is achieved with the characteristics according to claim 1, wherein in Rolling direction after the last deformation stand a switchable fürgangsKühlrange is formed with a plurality of concentrically arranged around the rolling, longitudinally differently positionable distributor rings for the cooling medium in each case with at least 3, each directed substantially to the Ax nozzles, each distributor ring or each group of the same throughput controlled the cooling medium is anspeisbar.
  • a device according to the invention it is advantageously possible with a device according to the invention to subject tubes having a different longitudinal extent and with different diameters and wall thicknesses to a targeted heat treatment from the rolling heat, such that a desired microstructure, which is represented uniformly over the tube length, can be obtained.
  • the coolant stream can be designed in each case as a spray stream of coolant, usually water, and / or as a spray stream of coolant and air and / or as a gas stream.
  • Essential to the invention are a switchability and throughput controllability of the coolant flows in the through-flow cooling section.
  • regulations for tube cooling with position and temperature sensors are used to control the coolant flows.
  • Example 1 from tube pre-material of the same mother melt with a chemical composition in wt .-% according to Tab. 1 description C Si Mn P S Cr Ni Cu al Not a word Fe RVM ⁇ 0.1819 0.2910 1.4231 0.0146 0.0065 0.0415 0.0275 0.0211 0.0274 0.0126 rest Finally, by means of stretch-reducing tubes with the following dimensions were produced: Pipe length (rolling stock) (L) 19,300.00 mm Pipe diameter ( ⁇ ) 146.00 mm Pipe wall thickness 9.70 mm
  • the tube was introduced after a time of 12 sec at a temperature of 880 ° C in a through-cooling.
  • microstructure revealed that at most there was in each case an advantageously rectified microstructure, essentially without texture, but with a grain size and microstructure distribution dependent on the final cooling temperature.
  • Fig. 1 shows a structure of sample P1, wherein a particle size of 20 to 30 microns was present at high ferrite content.
  • the further structural component was essentially perlite.
  • Perlite and microstructures of the upper intermediate or upper bainite were the other components of the compensation structure.
  • Fig. 5 shows in a bar graph the measured values yield strength (Rp) (0.2) [MPa], tensile strength (Rm) [MPa], constriction (Ac) [%] and toughness (KV450) [J] of the samples P1 to P4, ie depending on the achieved by the different cooling parameters in the annealing technology, mechanical material properties.
  • the yield strength of the material of the pipe wall can be increased by a process according to the invention from 424 [MPa] to 819 [MPa] and at the same time minimizing the drop of the elongation values from 26 [%] to 10 [%], the material toughness from 170 [J] to 160 [J] decreased.
  • microstructures in the material are adjustable, resulting in the property profile of the pipe wall results.
  • sample tube P4 owing to the low transformation temperature, a high degree of conversion into a lower bainitic structure of the microstructure could be achieved, as a result of which an increase in the toughness of the material could be achieved.
  • Fig. 6 shows the measured hardness values over the pipe length of test tubes P1 and P4.
  • Fig. 7 the hardness profile of the material in the quadrant is shown over the pipe wall thickness of the test tube P2.
  • the measurement results of the four quadrants Q1 to Q4 are averages of four spaced measurements per quadrant in the outer, middle and inner regions of the tube wall.
