“…The authors [17,18] carried out the detailed analysis of temperature and deformation parameters of RSR based on FEM results and experimental rolling. The perspectivity for combination of piercing and RSR process for obtaining the pipes from copper alloys for electrical purposes is shown in [19].…”

“…Different guiding tools are applied in two-high screw rolling mills to keep the billet in the deformation zone. The guiding tools could be guiding shoes, and such mills are called Mannesmann mills [ 2 , 3 , 4 , 5 , 6 ]. Guiding disks are applied in two-high mills of the Diescher type [ 7 , 8 , 9 , 10 , 11 ].…”

AA6060 ingots were pierced in a two-high screw rolling mill (MISIS-130D) with guiding shoes (Mannesmann mill type). Three different plugs, i.e., a conventional entire plug, a plug with a cavity, and a hollow plug, were used for piercing. We established that the grain size decreases after piercing, by order of magnitude, compared to the initial non-pierced annealed bill, with a grain size of 100–400 μm, and the hollow shell grains are elongated along the piercing direction. The produced hollow shells had 30% higher hardness than the initial billet. The highest hardness values were obtained after piercing the conventional entire plug. The most uniform hardness distribution through the hollow shell’s volume was obtained after piercing the hollow plug. The cross and longitudinal section hardness measurements demonstrate that the hardness decreases from the outer surface to the inner surface of the hollow shells.

“…Gamin et al 2 studied the benefits and defects of two rolls and three rolls for different applications. The obtained results suggest that the process via two rolls can create the high accuracy in terms of the surface roughness of the tube and the other hand this procedure includes the less weight of the equipment and with the manufacturing flexible.…”

The rotary tube piercing (RTP) is the first process of making the seamless tube after producing the desired alloy ingot. There are several approaches to manufacture a seamless tube, but one of the most common types is RTP. This approach covers a wide range of processes that are categorized according to the number and shape of the rollers. On the other hand, each of these types has designed guides in the output and input of the piercing process. In this paper, a new design of the input guide for four types of rollers have been examined and simulated. Thus, four specimens including Diescher and Conical rollers were considered, with the different number of rollers. Results including torque, total force, mandrel wear, temperature distribution, and strain were extracted using FEM simulation. In order to the validation of simulation, the total force and oscillations of applied force within the process have been compared with the experimental results. The results obtained through this simulation, are more in line with the empirical results obtained from previous research. As well as, the FEM simulation confirmed the performance accuracy of the output and input guides of the RTP process. On the other hand, the results indicate that the three-roller Diescher type with 17° feed angle, has the most suitable arrangement for production of seamless tube.
