德聶伯罗彼得罗夫斯克列宁轧管厂从1964就对140轧管机组(图1)进行了改造和改装的工作,更换了旧的部件和组合件,并使轧机的全部工艺设备机械化和自动化了。穿轧机安装了新的同步电动机,其功率为2000瓩,转数为2 50转/分。同时改造了穿轧机的齿轮机座,因而可使轧辊转数从108相应地提高15%。 The Dnipropetrovsk Lenin Mill commissioned the renovation and retrofitting of the 140 tube rolling mill (Figure 1) from 1964, replacing the old components and assemblies and mechanizing the entire process plant for the mill Automated. A new synchronous motor was installed on the mill, with a power of 2000 瓩 and a rotation speed of 250 rpm. At the same time, the gear stand of the mill was modified so that the number of rotations of the rolls can be increased by 15% from 108.
