冶金工业的变频器应用与维护(六) 变频器在金属拉丝中的应用

The AC Inverter’s Application and Maintenance in the Metallurgical Industry

常见的拉丝机包括直进式、活套式、滑轮式和水箱式几种,在以前通常都采用直流电机或发电机-电动机组(F-D系统)来实现,现在随着工艺技术的进步和变频器的大量普及,变频控制开始在各式拉丝机中大量使用,并可通过PLC来实现拉拔品种设定、操作自动化、生产过程控制、实时闭环控制、自动计米等功能。

The common drawing machines include straight wire drawing machine, live sets, pulley and tanks type. Usually these machines workeds by using the DC motor or generator - motor group （FD system） . Now with the advances of the technology and popularity of inverter devices, AC inverters are being extensively adopted in various types of wire drawing machines. By using PLC and AC inverter, the drawing machines can achieve the functions such as automatic operation, process control, real-time closed-loop control, automatic meter functions, etx.
