Abstract
Research of the Tool Velocity and Product Shape Aspects of the Hot Radial Rolling of C45 Steel Rings
Highlights
Hot ring rolled products are widely used in numerous structures, from small bearings to large parts used in automotive, railway, power or chemical industries
This paper presents the results of a study investigating the hot radial rolling process for C45 steel rings in terms of the effect of main roll feed speed on product geometry
It was found that the application of a higher feed speed of the main roll and of a greater ratio between this speed and circumferential speed of the main roll led to increased axial material flow and reduced cross-sectional defect known as ”fishtail”
