以三元模型法为基础,建立了带钢在立式炉内退火全过程的数学模型;模拟计算了带钢和退火炉的温度场;讨论了操作参数对带钢加热的影响以及冷却气体初始温度和喷射速度对带钢冷却过程的影响。其模拟的带钢加热曲线与工艺要求相吻合,为带钢温度的预测和合理的炉温决策创造了有利条件。
Based on the ternary model method, the mathematical model of the whole process of strip annealing in a vertical furnace was established. The temperature field of strip and annealing furnace was simulated. The influence of operating parameters on strip heating and the initial cooling gas Effect of Temperature and Jet Speed on Strip Cooling. The simulated strip heating curve is consistent with the process requirements, which has created favorable conditions for strip temperature prediction and reasonable furnace temperature decision-making.
