RESEARCH ON THE EFFECT OF THE GROOVING OF MILL ROLLS OF THE REELING TUBE MILL ON THE WEAROF THE ELONGATING MANDREL
By means of numerical simulation the influence of the geometry of calibers of mill rolls on the wear of the elongating mandrel is determined. The type of the grooving of mill rolls of a continuous three roll reeling mill, which reduces the wear of the elongating mandrel during the rolling, is determined.
