Abstract:
Based on medium plate runout table ultra-fast cooling (UFC)-accelerated cooling equipment (ACC) system, a heat transfer coefficient model was constructed. Firstly, according to the measured data, heat transfer coefficients under different roll speed and water volume were calculated by using an inverse heat conduction method. Secondly, a monofactorial heat transfer coefficient calculation formula was obtained. Finally, the heat transfer coefficient model based on medium plate runout table UFC-ACC system was constructed by intercept function, slope function, interaction influence function and linear or nonlinear influencing factors. The precision of these models was validated by comparing model prediction value with measured data, and the results were in good agreement with practical needs, and the average deviation was less than 5％.
Key words: medium plate ultra-fast cooling heat transfer coefficient mathematical model
