Изобретение относится к прокатному производству и может быть использовано при термоупрочнении труб в линиях станов горячей прокатки. С целью исключения попадания воды внутрь трубы в процессе закалки при осуществлении способа прокатки труб с термомеханической обработкой, включающего нагрев, прошивку заготовки в гильзу, прокатку ее на непрерывном стане, стабилизацию температуры черновой трубы, редуцирование, закалку струями охладителя готовой трубы, в отличие от известного, деформируют внутрь черновой трубы часть периметра переднего торцевого участка. Кроме того, деформируют внутрь черновой трубы часть периметра заднего торцевого участка. Закалку готовой трубы осуществляют струями охладителя, направленными навстречу движению трубы.The invention relates to rolling production and can be used for thermal strengthening of pipes in the lines of hot rolling mills. In order to prevent water from entering the inside of the pipe during quenching when carrying out the method of rolling pipes with thermomechanical treatment, including heating, stitching the workpiece into the sleeve, rolling it on a continuous mill, stabilizing the temperature of the draft pipe, reducing, quenching the finished pipe cooler, unlike the well-known , deform inside the draft pipe part of the perimeter of the front end portion. In addition, the part of the perimeter of the rear end portion is deformed into the inside of the draft pipe. The hardening of the finished pipe is performed by the streams of the cooler, directed towards the movement of the pipe.
