Abstract: The temperature of hot strip at finishing rolling interstand has been calculated by established short-cut calculation model and defined concept of equivalent interstand distance and fundamental value. The comparison between shortcut method calculated results and theory model calculated results showed that the temperature of hot strip at finishing rolling region could be calculated accurately. As target temperature is changed the status of cooling jet at interstand can be adjusted by short-cut calculation method to fit in with new target temperature.

摘要： 通过所建立的热带终轧过程计算的简化模型和确定的当量间距基本值,计算热带在精轧各机架间的温度。简便计算结果和理论模型计算结果的对比表明,简便计算方法能较精确地计算热带在精轧区的温度。当目标温度发生变化时,用简便计算法可以调整机架间喷嘴状态以适应新的目标值。
