“…Due to the market growth and demand for high-quality products, tubular manufacturers as well as service pipeline systems shall keep steady developing. Steel pipes used in different industries are classified into seamless [1][2][3][4] and welded pipes [5][6][7][8] depending on the manufacturing process. Currently, seamless pipes are widely used in various industries due to high strength under high pressure and other properties including corrosion resistance as compared to welded pipes [9,10].…”

The present article discusses the cylindrical mandrel wear change during rolling using MISIS - 130 D mill depending on the type of rolled billets materials used. The research on the mandrel wear of the screw rolling mill during pipes elongation was carried out using the finite element method (FEM). The results of the wear modeling showed that the depth of the metal removed on the mandrel surface during stainless steel pipes elongation was higher as compared to alloyed and carbon steel pipes. The significant wear of the mandrel during stainless steel pipe rolling can be explained by the rise in the applied metal force resulting from the introduction of alloying components such as chromium and nickel into rolled billets materials. Consequently, the obtained modeling results can allow predicting the service life of working tools.

A technique was developed for the numerical analysis of the thermal state of long mandrels of a three-roll rolling mill using modern computer simulation software. The initial and boundary conditions were determined taking into account the peculiarities of rolling in a three-roll screw rolling mill on a long mandrel. The authors carried out a qualitative assessment of the thermal state of a long mandrel by means of visualized representation and established its significant inhomogeneity. Influence of the rolling temperature and diameter of the long mandrel were revealed. Small diameter mandrels are heated to higher temperatures (577 °C) with a significantly lower gradient between the axial zone and the surface. An increase in the mandrel diameter to 154 mm lowers the temperature of the outer surface to 530 °C and increases temperature gradient in the near-surface layers up to 18 °C/mm. So the temperature in the near-surface layers for a mandrel of 154 mm at a distance of 10 – 15 mm from the surface decreases from 530 °C to 315 °C. Features of the temperature field in the cross section were established taking into account thermal interaction of the sleeve with the mandrel in the zone of contact with hot metal and in gaps between the rolls. Temperature of the near-surface layers in the contact zone is 30 °C higher than in the gaps. Dependences of temperature of the cross-section characteristic points on the rolling time were determined, it has been established that in the first two seconds there is an intense growth according to the parabolic, and then according to the linear laws. Temperature of the central layers with a radius of 50 mm increases with a much lower intensity, by about 100 °С during the entire period of rolling, while during the same time, the near-surface layers are heated by 300 – 400 °С.
