双机联合拖动差动调速连轧机调速系统,是一种电气和机械方法并用的新型调速系统。它既发挥了交流电动机机械特性硬之优点,又吸取了直流电动机调速方便灵活之精华。本文以差动调速连轧机调速系统的设计和近两年成功的生产运行为依据,介绍了差动调速连轧机调速系统的原理,提出了既切实可行又经济实惠的设计方案,讨论了避免非正常工作状态的措施。
Double machine dragging differential speed control continuous mill speed control system, is a combination of electrical and mechanical methods and a new speed control system. It not only exerts the advantage of hard mechanical characteristics of AC motor, but also absorbs the essence of convenient and flexible DC motor speed regulation. In this paper, based on the design of the speed control system of the differential speed control continuous rolling mill and the successful production operation in the past two years, the principle of the speed control system of the differential speed control continuous rolling mill is introduced. The feasible and economical design scheme is put forward, Discussed the measures to avoid abnormal working conditions.
