Mathematical model for the thermal process of controlled cooling of wires and its numerical simulation

摘要

The mathematical model for the thermal process of billets rolling has been established, including transporting in air and temperature-holding cover, descaling with high-pressure water, and the process of rolling and cooling in water box. The calculated data by the model have been compared with the measured data and the results show that the model is right and creditable. Based on the model, the main thermal characters of rolling line have been simulated and the influence of all the parameters on the temperature of rolling has been analyzed.
