Thermal Behavior of a Hot Moving Steel Strip Under Multi-Cooling Jets
In the present work, the thermal behavior during cooling of a steel strip is predicted numerically. Multiple jets of pressurized water are considered for cooling purposes; they impinge on the surface of the metal strip. The cooling of the metal strip is represented by a steady-state energy conservation equation, where an effective heat transfer coefficient is considered based on jet and strip velocities for jet-surface heat interaction. The numerical simulation is performed using a finite-volume method, and distribution of temperature within the strip is predicted. Subsequently, the effect of strip velocity on the temperature distribution and corresponding cooling rate is studied.
