We propose a technology for the production and piercing profiled pipe billets with an aim to improve the precision of hollow billets and pipes. To obtain profiled billets, it is reasonable to use a three-roll primary mill with specially designed rolls and profiling ridges. Both computer simulations carried out by using the QForm 3D program and the results of experimental rolling carried out at the Chair of Metal Forming of the “MISiS” University reveal an increase in the precision of the wall thickness of the hollow billets.

使用异型管坯提高管子精度

我们提出了一种生产和穿孔异型管坯的技术,旨在提高空心坯和管的精度。为了获得异型坯,使用具有特殊设计的轧辊和异型脊的三辊初级轧机是合理的。使用 QForm 3D 程序进行的计算机模拟和在“MISiS”大学金属成形主席处进行的实验轧制的结果都表明,空心坯壁厚的精度有所提高。
