摘要
介绍了广州广钢控股公司无缝钢管厂对其700kN冷拔机的直流调速系统进行改造的实践。该改造使用国产可控硅,并科学选择其各种参数,同时对检测单元进行匹配改造,实现了扩容目标。
This paper describes the practice of modification of 700kN cold-drawing machine＇ s DC speed controller. Domestic thyristor was used, and the parameters of thyristor were selected in a scientific way. At the same time testing unit was modified correspondingly, and enlargement goal was reached.
