西安重塑机械研究所研制的Assel轧管机(见封面)技术性能如下:毛管直径:小40一中58最薄壁厚:Zlnm外径精度:不大于士0.5%壁厚精度:不大于士5%此轧机用来轧制碳素钢管、合金钢管、轴承管等。轧制中可单独使机架回转或轧辊快开,也可使两者同时动作以便消除钢管末端尾三角。其结构简单,可靠,功能多,解除卡轧事故容易,并采用电动半浮式芯棒。本机运行两年情况表明,设计是合理的。
The technical performance of Assel tube rolling mill (see the cover) developed by Xi’an Resurfacing Machinery Institute is as follows: Capillary diameter: 40 to 58 mm Thinnest wall thickness: Zlnm Outside diameter accuracy: not more than ± 0.5% Wall thickness accuracy: Not more than ± 5% This mill is used to roll carbon steel pipe, alloy steel pipe, bearing pipe and so on. Rolling can be a separate rack rotation or roll quickly open, but also make both the action in order to eliminate the tail end of the triangle pipe. The structure is simple, reliable, multi-function, easy to lift off the card rolling accidents, and the use of electric semi-floating mandrel. The two-year operation of this machine shows that the design is reasonable.
