Three-dimensional hot rolling model for prediction of camber generation

Abstract A three-dimensional explicit finite element model of the hot rolling process has been developed and used to investigate the generation of camber during the roughing stages of this process. A number of important contributing factors have been studied in detail in an effort to predict their combined effects on camber generation. Predictive equations have been derived which can be used to estimate the level of camber, given suitable values of the dominant process variables. A parallel experimental study has also generated similar empirical relationships. There is reasonable comparison between the predictive and empirical equations, and causes of minor discrepancies are discussed.
