摘    要：提出了一种热卷箱与粗轧和精轧互为主从的主令速度控制新方法。建立了主令速度分区控制思想,并提出了主令速度分解及单体设备速度补偿策略。该方法具有大型轧钢控制中强调区域协调性的优良特点,建立了合理而紧凑的带钢轧制节奏。工程应用验证了该方法的有效性和实用性。

Abstract: A new approach to master speed control is proposed,in which coil box and roughing mill and finishing mil are combined with each other as master-slave device.An idea of controlling the master speed by zones is adopted,and tactics of the master speed resolving and single device’s compensation are presented.The method has a good character which is emphasized on the coordination among zones in large-scale rolling mill controlling and forms a reasonable and compact strip rolling pace.The effectiveness and practicability of the method was verified in engineering applications.
