Abstract
Способ производства горячекатаных труб диаметром 114 мм из непрерывно-литой заготовки диаметром 150 и 156 мм, включающий прошивку заготовки, прокатку трубы, калибровку отличающийся тем, что прокатку трубы осуществляют в двух последовательно расположенных станах продольной прокатки в валках с многогранными калибрами с числом граней больше 6-ти и высотой калибра первого стана больше высоты калибра второго стана на 1-2 мм, при этом прокатку ведут на коротких оправках, которые имеют наружные диаметры, равные наружному диаметру оправки первого стана или наружный диаметр оправки второго стана на 1-2 мм меньше наружного диаметра оправки первого стана с вытяжкой в первом стане µ=1,1-1,5 и µ=1,05-1,15 во втором стане, а калибровку трубы с вытяжкой µ=1,1-1,3 выполняют в калибровочном стане с диаметром калибра в последней клети 114,0-117,0 мм.A method of manufacturing hot rolled pipes with a diameter of 114 mm from a continuously cast billet with a diameter of 150 and 156 mm, including piercing the billet, rolling the pipe, and calibrating, characterized in that the pipe is rolled in two consecutive longitudinal rolling mills in multi-faceted rolls with more than 6 faces and the height of the caliber of the first mill is greater than the height of the caliber of the second mill by 1-2 mm, while rolling is carried out on short mandrels that have outer diameters equal to the outer diameter of the mandrel of the first st on or the outer diameter of the mandrel of the second mill is 1-2 mm less than the outer diameter of the mandrel of the first mill with an extract in the first mill µ = 1.1-1.5 and µ = 1.05-1.15 in the second mill, and the calibration of the pipe with extractor µ = 1.1-1.3 is performed in a calibration mill with a caliber diameter of 114.0-117.0 mm in the last stand.
