自动轧管机组均整机孔型的改进

Improvement on Reeling Machine Pass of Automatic Tube Rolling Mills

对Φ219自动轧管机组均整机锥形辊进行了新的设计,改进了均整机孔型,优化了均整工艺,使均整机轧制过程更为可靠,轧制出口速度明显提高,进出口变形区的轧制力分布更加均匀。

By a new design on cone .shaped roll of reeling machine in Ф219 automatic robe rolling mills being carried, the pass of reeling machine is improved and the reeling technique is optimized to make a more reliable rolling process , obviously increased rolling rate at exit and more uniform rolling force distribution at inter and outer deformation zoner
