本装置系为φ38五机架钢管连轧机可控硅供电装置,因为是连续轧管又不可能形成活套,故要求电气传动装置摔制系统调节速度要快,动态速度降要小,恢复时间要短,同时要各机架的速度按轧制工艺要求保持一定的关系。工艺变更时,各机架速度连续可调,以满足工艺要求。根据76年7～8月和77年1月底～2月初先后进行了连轧管浮动芯棒与限动芯棒轧制试验,结果证明本装置能满足试验轧机的要求。
The device is φ38 five-rack steel tube rolling mill SCR power supply device, because it is impossible to form a continuous tube rolling tube, it requires the electric transmission system falls faster adjustment system, the dynamic speed drop is smaller, the recovery time Should be short, at the same time to the speed of the rack according to the rolling process to maintain a certain relationship. Process changes, the rack speed continuously adjustable to meet the technical requirements. According to the test of floating mandrel and mandrel bar with continuous mandrel from July to August in 1976 and the end of January to early February in 1977, the results show that the device can meet the requirements of the experimental mill.
