Analytical Prediction of Thermal Behaviour during Cooling of a Hot Steel Strip

Abstract:

Article Preview

The present work predicts the thermal behavior of a hot steel strip analytically where the strip is cooled with water spray. The cooling process is represented by a steady 2-D energy conservation equation. An effective heat transfer coefficient is considered to represent the water spray and the strip surface heat interaction. The solution considers the separation of variables method with appropriate boundary conditions. Finally, the work involves quick evolution of temperature variation in the strip. It is found that the present analytical prediction agrees well with numerical prediction.
