Determination of Power Output and Impact on the Rheological Parameters of Raw Materials during Rolling

Abstract

The paper presents mathematical modelling of determining the power output over the rolling materials in the gap rotating rollers taking into account the rheological parameters of the final product. Determination of these parameters will reduce energy consumption, increase efficiency and reduce loss of material during production. This solution, suggested in the article, allows determination of the overall quality of the rolled product layer. Analysis of experimental results revealed that the main features of the machine provide the necessary stable shape products and provide good rheological parameters of these products. Rheological testing indicators allow for a rational approach to a decision to operate a rolling process. At the same time they improve quality control methods and will have an impact on the design parameters of rollers and modes of chambers. The proposed method not only allows obtaining a predetermined pressure, but also allows defining the optimal shape of the gap, wherein the pressure gradient is constant.
