What is the effect of cold rolling speed of precision steel tube on external diameter and wall thickness?

    Precision steel pipe The cold rolling speed has a certain influence on the diameter. As for the extent of the influence, we will introduce it in detail in the small edition today

The cold rolling speed of precision steel tube has a great influence on the productivity of pipe drawing machine. High speed cold rolling can shorten the cold rolling cycle and improve the drawing productivity. At present, the drawing speed of domestic technology machine has reached 40 m / min (adjustable speed), and that of foreign machine has reached 100 m / min.

Generally, the higher the cold rolling speed of precision steel tube is, the greater the axial movement speed of metal in the deformation zone is, and the larger the diameter reduction of seamless steel tube drawn by empty drawing is. However, the experimental study on 300KN adjustable speed drawing machine shows that the cold rolling speed has little effect on the diameter reduction of the empty drawing pipe, which may be due to the slow cold rolling speed. Therefore, it can be considered that low speed cold rolling has little effect on the diameter reduction of precision steel pipe.

The above is about the impact of the cold rolling speed of precision steel pipe on the diameter. I hope the summary of the small series will be helpful to you. If you want to know more about the precision steel pipe, please pay attention to the update of this station.
