Partitioning of Power in Flat Rolling

Abstract

The metal rolling industry is in continuous demand for increasing the efficiency of the process. A new method of partitioning the consumed power in plate rolling into its constituent parts is presented. The proposed model takes into consideration the spread of workpiece, making it applicable to more general situations where the height to length ratio is equal to or larger than one. A mathematical model is proposed to calculate the consumed power and calculate different losses in the rolling operation. The method is easy and computationally efficient, which makes it attractive to industrial application.
