Research on metal reflow law of three roll skew rolling (TRSR) hollow axle
Metalurgija, 2022 In the process of TRSR hollow axle, there is metal reflow on the surface of the rolled piece, which greatly reduces the forming accuracy of the rolled piece. To solve this problem, it is necessary to study the metal reflow law of axle body.

Textures of Non-Oriented Electrical Steel Sheets Produced by Skew Cold Rolling and Annealing
Metals, 2021 In order to investigate the effect of cold rolling deformation mode and initial texture on the final textures of non-oriented electrical steels, a special rolling technique, i.e., skew rolling, was utilized to cold reduce steels.

Formation mechanism and control of the spiral marks of three-roll skew-rolled hollow axles
Metalurgija, 2021 The spiral marks is one of the main surface quality defects of the three-roll skew rolled hollow axles. In order to eliminate the spiral marks, it is necessary to clarify the cause of the spiral marks on the surface of the rolled piece.

Problems of forming stepped axles and shafts in a 3-roller skew rolling mill
Journal of Materials Research and Technology, 2020 The paper focuses on a new method for forming axisymmetric parts of considerable length in a CNC skew rolling mill. The laboratory rolling mill was used to conduct rolling tests for car axles (in scale 1:5). Although produced parts are free from internal

Short-Flow Rolling Process and Heat Treatment of Seamless Titanium Alloy Tube
Metals, 2023 In view of the material characteristics of titanium alloys, such as their capability to quickly cool down and their poor machinability, in this study, we combined a new production mode for seamless tube rolling (tandem skew rolling, TSR) with titanium ...
