Abstract

La presente proporciona un método de laminación controlada de tubos de acero sin costura de excelente resistencia y alta tenacidad a baja temperatura para ser aplicado a un proceso de fabricación de tubos de acero sin costura. Este método de laminación controlada comprende la realización de una laminación-perforación en la zona de recristalización de la fase g (aproximadamente 950ºC o superior); la realización de laminación-alargamiento y la laminación-reducción en la zona de no-recristalización de la fase g (950ºC a punto de transformación Ar3) en el paso de laminación-alargamiento y en el paso de laminación-reducción; y la realización del enfriado controlado o del templado inmediatamente después de la laminación-reducción. Si se utiliza un calibrador en el paso de laminación-reducción, la laminación en la zona de temperatura de fase dual (a + g) (punto de transformación Ar3 a punto de transformación Ar1) se efectúa en el paso de laminación-reducción. El presente método de laminación controlada puede resolver problemas de aumento significativo de la resistencia a la deformación en caliente y de deterioro importante de deformabilidad en caliente (facilidad de elaboración en caliente) debido a la laminación a baja temperatura, y puede producir tubos de acero sin costura de excelente resistencia y alta tenacidad a baja temperatura, conjuntamente con el uso de un método de enfriamiento controlado.The present provides a method of controlled rolling of seamless steel tubes of excellent strength and high toughness at low temperature to be applied to a manufacturing process of seamless steel pipes. This controlled lamination method comprises performing a lamination-perforation in the recrystallization zone of phase g (approximately 950 ° C or higher); the realization of lamination-elongation and lamination-reduction in the non-recrystallization zone of phase g (950 ° C at transformation point Ar3) in the lamination-elongation step and in the lamination-reduction step; and the performance of controlled cooling or tempering immediately after lamination-reduction. If a calibrator is used in the lamination-reduction step, lamination in the dual phase temperature zone (a + g) (transformation point Ar3 to transformation point Ar1) is carried out in the lamination-reduction step. The present controlled lamination method can solve problems of significant increase in resistance to hot deformation and significant deterioration of hot deformability (ease of hot processing) due to low temperature lamination, and can produce steel tubes without Excellent strength sewing and high tenacity at low temperature, together with the use of a controlled cooling method.
