New metal-saving technologies of hot tube rolling on pilgrim units

Analysis of experimental and analytical data of pilgrim units type 5-12” work results of the past 20 years allowed to develop new technological schemes and methods of their implementation. Different schemes for preparation of front and back ends of the case, joint rolling of tubes with thin and thick walls, methods of withdrawal of the tube from mandrel and its calibration were evaluated. Complex application of the research results allows to significantly reduce metal consumption coefficient from 1.18 to 1.09 which allows the process to be competitive on the market.
