The method of straight seam steel tube in preheating deformation

Update:2020-04-21   View(s):78   Keywords :straight seam steel tube

1. Reasonable material selection, reasonable selection of heating temperature, and control of heating speed.

 

2. Correct heat treatment process operation and reasonable tempering heat treatment process are also useful methods to reduce the deformation of precision messy molds.

 

3. Precise messy molds should be preheat treated to eliminate the remaining stress during mechanical processing.

 

4. The mold planning and depiction should be reasonable, the thickness should not be too wide, and the shape should be symmetrical. Preheat treatment, aging heat treatment, tempering and nitridation heat treatment can be used to control the precision of the mold for some precise and messy molds.
