一、合理确定主传动 调速幅度的重要性 为了协调连轧机各机架轧速,调节通过各机架的金属秒流量、调节轧件所受的张力以适应产品规格的变换,连轧机主传动必须能调速且需具有必要的调速幅度。 在传统的以直流电机为主传动的“直流连轧”中,主传动的调速范围已经定型于二至二点五倍:即电机弱磁后的最高转速为 First, a reasonable determination of the importance of the speed of the main drive speed In order to coordinate the rolling mill rack rate, adjust the flow through the metal frame, adjust the tension of the rolling stock to adapt to product specifications change, even the mill main drive Must be able to speed and need to have the necessary speed range. In the traditional DC motor-based transmission “DC continuous rolling”, the main drive speed range has been set at two to two five times: that is, the maximum motor speed after the flux is
