Abstract

When the width, thin steel strip is produced by hot tandem rolling, hot coil box technology is usually adopted, which is one of the key links in the entire production line. The hot coil box has a heat preservation effect on the transfer bar, which makes the temperature distributed uniformly, reducing energy consumption. Thus, it can improve product quality, and is beneficial to the control of thickness and shape. The temperature prediction of the transfer bar is very important, and its accuracy affects the calculating accuracy of the rolling force and the forecasting of the microstructure for strip in the finishing rolling. This paper investigates the temperature distribution of transfer bar from the rough mill delivery to the finish mill entrance. The boundary conditions for transfer bar passing across the transfer table and the equivalent thermal conductivity of the transfer bar coil are studied, finite difference equation is established. Temperature evolution of transfer bar and the influence of different process parameters on the temperature are obtained. Finally, the high accuracy of the model is verified by the measured data.
