The Causes and Improvement Measures of Fold Defects in Cold Formed Strip Steel Coils
This paper summarizes and analyzes the generation rules and influencing factors of fold marks in cold formed strip steel coils.Through on-site experiments,it is determined that the main influencing factor of fold marks in coils is the winding state of the leading end.By adding a three roll straightening equipment before coiling,the warping state of the strip steel entering the coiling process is changed,effectively improving the coiling fold marks.
