分析了全氢罩式退火炉退火工艺过程的传热特点,建立了以板卷温度计算为核心 的退火热过程数学模型,通过模拟计算得到了钢卷退火曲线,并与实测值进行了对比验证. 结果表明,该数学模型合理、可靠. The characteristics of heat transfer during the annealing process of the full hydrogen annealing furnace were analyzed. The mathematical model of the annealing process with the calculation of the coil temperature as the core was established. The annealing curves of the coil were obtained by simulation and compared with the measured values The result shows that the mathematical model is reasonable and reliable.
