【Beginner in Static Equipment】What to do if thick steel bars deform during cutting?
Thread Content
While cutting thick steel bars, I noticed that they deformed during the cutting process. What should I do?
It is said that if a little is left uncut, this problem won’t occur; is that true?
Flame cutting with such narrow strips will definitely cause deformation; if there are multiple strips, CNC multi-nozzle cutting can be used to control the deformation. However, if only one strip needs to be cut, flame straightening or mechanical straightening must be employed.
It was found that this phenomenon occurs whenever narrow strips are cut. Is it caused by the deformation resulting from the contraction of the cut edges after heating and cooling? Then why do they bend towards the side that hasn’t been cut? ? ?
Do you think the method mentioned on the second floor is effective?
It’s not very useful; just correct the shape after cutting

Deformation occurs due to uneven heating; if the workpiece can be heated evenly, the deformation will be much smaller, to the point where it’s barely visible to the naked eye. However, this is difficult to achieve; even when using multiple nozzles, the flame size of each nozzle is not the same ； However, the deformation will be much less.
For such narrow strip materials, mechanical shaping is still the better option.
This method is quite good; wait until both ends have cooled to room temperature before cutting
