Production of High-Quality Bars of Hypereutectic Silumins by Helical Rolling

A study is made of the possibility of improving the structure and properties of hard-to-deform hypereutectic silumins with the use of helical rolling (HRG) on the PVP 20-60 universal mill at the All-Union Scientific Research Institute of Light Alloys.

Description
Summary:A study is made of the possibility of improving the structure and properties of hard-to-deform hypereutectic silumins with the use of helical rolling (HRG) on the PVP 20-60 universal mill at the All-Union Scientific Research Institute of Light Alloys. The parameters of hot HRG are optimized by numerically modeling the deformation process in a three-high stand. The resulting data is confirmed experimentally by subjecting standard hypereutectic silumins 01390 and 01391 to HRG. The use of HRG makes it possible to refine the structure of hypereutectic silumins and improve their mechanical properties.[PUBLICATION ABSTRACT]
