Twisting of cold rolled steel sheet during PVC coating




December 2, 2008

Hi,

My name is Turgut Kirma. I am a metallurgical and materials engineer and I am working in a Steel Company in Turkey. My problem is, our cold rolled steel sheets are twisting during PVC Coating Process. There is not any problem in mechanical properties and chemical analysis of sheet. The problem is interesting and I will be satisfied if you share your ideas with me.

Thank you and regards.

I would call it bending rather than twisting.
Since you do not say, I assume that the process involves heat. If it does you have higher stresses on one side of the sheet caused by the rolling process. When you add heat, you are allowing the stress to be reduced on the one side and it will curve away from that side. Try running a sheet thru the heat process with no coating and see if it does not bend.
Another possibility is that you have the PVC on only one side and as it cures it is contracting causing your bow.
