defects in wire-rod rolling most of the defects in wire-rod rolling can be detected either by the naked eye or with anon-destructive test, for example an eddy current test. this method works with a current screening the wire, detecting changes in the current where a defect is present. description and some of1.1. roll pass design roll pass design is an important field of rolling mill technology. In bar and wire rod rolling using grooved rolls, the cross-sectional area is reduced and the bar is elongated with large lateral spread. the function of roll pass design is to ensure the production of the desired shape, good surface without any defects and roll pass designs projects typically follow the following timeline: development of detailed groove drawings, roll barrel layouts, roll stress calculations, rolling power, torque and separating force predictions, and roller set-up sheets.the thesis treats roll pass design in wire rod rolling of stainless steel for sequences and series built up by two-symmetrical grooves. It is focused on predicting rolling flexibility, also called working range, as well as product quality. for analysing the flexibility a computer program has been developed.
