“…The study of pipe forming was carried out using «DEFORM -3D» software solution. Following the recommendations of the programmers and taking into account a practical data about pipes rolling on the PRM mill [10,11] The study of metal forming was carried out for two options of working rolls pass design: hexagonal and dioctahedral (Fig. 4).…”

The study proposed the model of "guide mark" defects formation on the internal surface of pipes, produced on PRM mills of PRP -140. The research of pipe forming at plug rolling mill with stub mandrel has been carried out; regularities of the dimensionless parameters characterizing the deformation of the gap release, depending on the reduction ratio, were determined. The model of "guide mark" defect formation on the internal surface of the pipe has been proposed. This allows for lesser wall thickness variation of rough tubes. It has been shown that, when using dioctahedral pass designs in comparison with hexagonal pass designs the proportion of displaced volume along the pipe axis is greater but the value is lower; thereby, the risk of "guide mark" defect forming is reduced.

A new method of hot-rolled pipes rolling on the automatic tandem mill is suggested. It consists of two rolling stands. This method allows achieving the rough pipe preovalisation before reaching the automatic mill. The rough pipe preovalisation provides even groove filling and the decrease of pipe wall thickness variation. The rough pipe preovalisation will allow increasing the elongation ratio from 1.5 to 2.0 on the lengthwise rolling stand no. 1 and decreasing the elongation ratio on the piercing mill, therefore the chance of rolling skin formation on the external surface of the pipe is decreased. The way to reduce the probability of the formation of a guide mark defect due to the kinematic tension during rolling on a stub mandrel with rough tube preovalisation is investigated. The influence of the kinematic tension factor on the pipe forming in the groove taper at a lengthwise rolling with rough tube preovalisation is explored.

Abstract. The article presents results of research on aluminum alloy rod ingots deformed on a lever-type radial forging machine, which was done to evaluate the influence of process parameters on the damage of the material. The research includes the design of a mathematical model of the deformation zone during radial forging on this machine type, which allows one to determine the stress-strain state of the ingot during forming and also to determine experimentally the physical-mechanical properties of the material after deformation on a lever-type radial forging machine with various reduction values. The data obtained by the theoretical and experimental approaches coincide and indicate the optimum values of the process parameters of forging on a lever-type radial forging machine, which lead to the healing of defects appearing during the plastic deformation of the material.
