Tube continuous rolling (TCR) is a beneficial method for the production of titanium pipes due to its high efficiency and shorter process, with the mandrel playing a crucial role. In this study, the mechanism of the mandrel and its influence on the TCR process were investigated in detail through numerical simulations and experimental tests. The analysis included a detailed examination of metal slip, tension, stress-strain field, temperature field, metal flow, and microstructure evolution for various mandrel diameter coefficient. As the mandrel diameter coefficient increases, the grains at the groove vertex are elongated and recrystallized grains appear. At the same time, the quantity of twins at the groove taper initially increases and then decreases. Therefore, the deformation mechanism at the groove taper changes from twinning to slip.

“…Wear, surface thermal cracking, and plastic deformation are common causes of high temperature working-instrument failure. Numerous studies have been carried to improve the wear resistance of mandrels and their working resource in the screwroll piercing mill during piercing [4][5][6][7] and plugging on mills of various types [8][9][10]. The authors of [11] consider the issues of process optimization focused on increasing service life of tools.…”

“…The finite element method is frequently used in numerical modeling to solve complex temperature-deformation problems during hot metal forming [12,13]. Many studies, for example, have used finite element simulation to study the wear of working tools of pipe-produced mills, such as a continuous rolling mill [8][9][10] and piercing mill of screw rolling [14]. The main aim of the present study is to use the finite element method to research the nature of wear on the mandrel surface during the plugging of stainless-steel billets into pipes on the screw rolling mill.…”

This paper aims to use the QFORM software package based on the finite element method with a view to computer modeling the wear process of rolled mandrels of the screw rolling mill MISIS - 130D while rolling stainless steel X12CrNiTi18-9 billets into pipes. The wear properties of the mandrels change as the plugging process occurred under various initial conditions. The results show that the wear rate on the mandrels in the reduction zone is more intense at a higher feed angle and distance between guide shoes. Wear distribution on mandrels surfaces can be improved by adjusting the velocity along the rolling side of the mandrels and replacing them with long fast-moving long mandrels. The simulation which results in this work can be used to predict the properties of working-tool wear, depending on the technical parameters, and rolling mode, which consequently increases the quality of rolling process fabrication products and the service life of tools.

“…The basic requirements for steel pipes are the dimensions accuracy [9][10][11] and a certain product specification level [12]. For this purpose, unique equipment is to be used and new wear resistant materials for the deformation tool are to be developed [13][14][15]. The issue of pipes quality enhancement is always relevant for the pipe industry.…”

The paper discusses the specific aspects of hot rolled seamless pipes manufacture using pipe rolling plants including screw-rolling mills. The method of accuracy enhancement of pipe dimensions, as well as external and internal surface quality improvement, is proposed. The article specifies the results of computer and physical modeling of the pipes mandreling process. The application of the mandreling process within the cage using different diameter mandrels is shown. We managed to decrease the typical mark caused by the metal deformation, due to the screw-rolling mill and to manufacture pipes with more accurate dimensions, as a result of the mandreling process modeling. The results of the physical experiment on mandreling the shell pierced at the screw-rolling mill showed a positive effect from the process of hollow billet cold treatment using the mandrel.
