本工作试制成功了用于测量主传动系统静、动态速降的比较放大器,它具有较高的灵敏度与响应速度。测试结果证实双电机差动调速系统的调速品质满足了连轧工艺的要求。差动调速连轧技术的优点是技术简单、易于掌握;旧有设备可充分利用、投资少、建设速度快。可以作为我国中小型轧机技术改造的方案之一。
This work trial successfully used to measure the main drive static and dynamic speed drop of the comparison amplifier, it has a high sensitivity and response speed. The test results confirm that the speed regulation quality of the dual motor differential speed control system meets the requirements of the continuous rolling process. The advantages of differential speed and continuous rolling technology are simple technology, easy to master; old equipment can make full use of less investment, construction speed. It can be used as one of the solutions for technological transformation of small and medium-sized rolling mills in our country.
