Definitions

  • This invention relates to metallurgy, referring specifically to welded pipe production for oil pipelines, natural gas pipelines, product pipelines and other similar designs (tanks, pressure vessels) which can be safely operated in adverse geological and climatic conditions, and in aggressive corrosive liquids.
  • the pipe and its method of manufacture is known (Patent of the Russian Federation No. 2180691 , C 21 D9/08, publication of 10.11.1999). It includes steelmaking, ladle processing, steel teeming, hot rolling (several rolling passages with predetermined deformation ratio), shape molding and welding.
  • T bgn -T end ⁇ 200
  • T bgn and T end are values of temperature at the start of hot roll and at the finish, accordingly.
  • the purpose of this invention is to provide combination of the required strength properties (breaking strength above 620 kg/mm 2 ) and high plasticity, ductility, crack resistance and resistance to corrosion in pipes and other products made from steel sheets up to 50 mm thick.
  • the required result is obtained due to the fact that the method for production of the above pipe includes steelmaking with the above content ratio, ladle processing, hot rolling, shape molding and welding of pipes.
  • hot rolling is performed in reversing mill or continuous mill with subsequent fast controlled cooling, its rate being determined by the following equation: T hot - T cold L ⁇ s ⁇ V s , °C / sec
  • Rate value in the process shall be according to the following: T hot - T cold L ⁇ s ⁇ V s > 4 , where T hot is the temperature of steel sheet or steel band in the end of rolling, its value being within 750°C -850°C range; T cold is the temperature of steel sheet or steel band in the end of fast controlled cooling, its value being within 500°C -700°C range; V s is the steel sheet or steel band speed in the sprinkler or laminar flow, m/sec; L s is the length of sprinkler or laminar unit (can be changed in the 10-100 m range).
  • Table 1 shows the chemical composition of steel in two pipes, one made in accordance with the composition offered and the other one - of a different composition.
  • the compositions were selected in such a way so as to estimate molybdenum and nickel contribution to steel sheet strength in different cooling conditions after rolling. Melting process was performed in a vacuum induction furnace. Furnace charge consisted of armco iron and, depending on variant of composition, of nickel, ferromolybdenum, copper and other charge materials. When the required underpressure in the furnace was achieved charge meltdown was started.
  • the ingots selected and the molten steel of a given pipe were forged into 80-430 mm plates; then they were rolled in a reversing mill to become 50 and 20 mm thick. After that the plates were fast-cooled at a rate of 10 and 20 degrees per second and alternately cooled in the open air. The latter cooling procedure corresponds to hot-rolled sheet conditions while the first two - to controlled fast cooling. The resulting sheets were then shaped and welded into pipes.
  • Table 2 shows the properties of these heats in comparison with heats of a known composition.
  • the obtained results demonstrate that the new steel of the above composition made in accordance with the offered rolling technology, which involves controlled cooling at a rate of 4°C per second, has the required combination of properties, such as high strength in 50-mm cross-sections and high tenacity, and therefore, good crack resistance and ductility in subzero temperatures.
  • the 10 m/sec sheet passage speed in controlled cooling has been obtained in a wide-strip rolling mill.
  • the sheet surface temperature at the end of rolling mill was 840°C;
  • the sheet surface temperature at the end of controlled cooling procedure was 640°C; the length of laminary machine - 60 m; the steel strip movement speed in the laminar stream - 3 m/sec.
  • the 20 m/sec sheet passage speed in controlled cooling has been obtained in a reversing mill.
  • the sheet surface temperature at the end of rolling mill was 800°C;
  • the sheet surface temperature at the end of controlled cooling procedure was 600°C;
  • the length of quench sprinkler was 10 m, the steel strip movement speed in the sprinkler was 1 m/sec.
  • the rate of steel sheet air cooling was approximately 2-3°C/sec. After cooling the sheet is shaped into pipe and its edges are welded.
