Physical Modeling of Cross Wedge Rolling Limitations.

This article presents the results of model tests aiming to verify the possibility of applying commercial plasticine as a model material for modelling the limits to the cross-wedge rolling process. This study presents a comparison of the results of laboratory testing and physical modelling of cross-wedge rolling (CWR) processes. Commercial plasticine was the model material used in the research to model 50HS grade steel formed in 1150 ˚C. The model material was cooled to 0°C, 5°C, 10°C, 12,5°C, and 15°C. Physical modelling of neckings and slippages is only possible when the plasticine is heated to 12.5˚C prior to forming. Commercial plasticine does not enable one to model the cracking process inside the rolled element.
