A Study on the 2-D Temperature Distribution of the Strip due to Induction Heater

Lowering the temperature drop of the hot strip in hot rolling process results in the increased rolling load and qulaity deterioration. The induction heating is the competitive way to heat the cooled bar. In this study, a two- dimensional thermal analysis has been performed to predict the temperature distribution along the width direction passing through the induction heater. In addition, correction coefficient for the amount of the cooling, Setting Power efficiency of the Induction Heater and heating efficiency is proposed to improve the prediction value.
