Gas cutting deformation of the rear smokebox~~
Thread Content
The rear smokebox is a thin plate~~ After gas cutting, there was a bulge on one side~~ We tried pressing it with a hydraulic press, and we also tried using a rolling machine~~ It seems flat at first glance, but when it’s lifted, the bulge reappears; the problem isn’t resolved~~ :Q :Q I remember that in our factory back then there was another rear smokebox that was curved; pressing it didn’t work, and rolling it first followed by pressing also didn’t help. Has anyone experienced this before?? :loveliness: How did you solve it?? :$ :$ There’s also the issue of welding deformation of the tube sheets~~:funk: :funk: And it’s always the rear tube sheets~~~- - That’s strange~~~~~~
Thermal stress deformation occurs, and to address it, the stress must be relieved.
