Abstract

1. Способ прокатки труб диаметром от 273 до 426 мм на трубопрокатных установках с пилигримовыми станами из углеродистых и низколегированных марок стали с повышенными требованиями к ударной вязкости, включающий нагрев заготовок до температуры пластичности, прошивку в стане поперечно-винтовой прокатки в гильзы, прокатку гильз на пилигримовом стане в трубы, калибровку труб в калибровочном стане и охлаждение на воздухе, отличающийся тем, что прокатку труб производят из стали микролегированной ванадием и ниобием или титаном и алюминием.2. Способ по п.1, отличающийся тем, что для прокатки труб используют заготовки с содержанием ванадия от 0,02 до 0,07% и ниобия от 0,01 до 0,03% или титана от 0,01 до 0,03% и алюминия от 0,02 до 0,05%.3. Способ по п.1, отличающийся тем, что прокатку труб на пилигримовом стане производят с подачами гильз в очаг деформации от 15 до 20 мм для труб с толщиной стенки от 10 до 15 мм и от 20 до 25 мм для труб с толщиной стенки от 15 до 20 мм.1. A method of rolling pipes with a diameter of 273 to 426 mm in tube-rolling plants with pilgrim mills of carbon and low alloy steel grades with increased requirements for impact strength, including heating the workpieces to a ductile temperature, piercing in a cross-helical rolling mill into sleeves, rolling the sleeves on a pilgrim mill into pipes, calibration of pipes in a calibration mill and air cooling, characterized in that the pipes are rolled from steel with microalloyed vanadium and niobium or titanium and aluminum. 2. The method according to claim 1, characterized in that for rolling pipes use billets with a content of vanadium from 0.02 to 0.07% and niobium from 0.01 to 0.03% or titanium from 0.01 to 0.03% and aluminum from 0.02 to 0.05%. 3. The method according to claim 1, characterized in that the pipes are rolled on a pilgrim mill with sleeves supplied to the deformation zone from 15 to 20 mm for pipes with a wall thickness of 10 to 15 mm and from 20 to 25 mm for pipes with a wall thickness of 15 up to 20 mm.
