A Numerical Study on the 2-D Temperature Distribution of the Strip on Run-Out Table of the Hot Mill

The cooling of steels on the run out table (ROT) has become a common practice in the production of hot rolled products. Therefore, the control of the cooling of the strip on ROT is an important issue in the strip steel production. Most of the researches performed at this moment deals with the simplified model and/or 1-D model. In this study, temperature distribution along the transverse direction has been investigated using the information collected from the onsite 1-D CTC log data. The simulator has been developed to predict temperature uniformity and to control the cooling rates of the strip. Several parameters such as correction factor and on/off density are optimized to calculate accurate cooling rate of the strip.
