The 2050 as the subject, reasons of the emergency of the roll wear in hot rolling process were analyzed, and off-line simulating calculation of the roll wear is carried out by adapting the spot on-line wear calculation model. After testing the wear curve of the roll on the grinder, comparison is made between theoretical results and the measured data. It is discovered that there is different distribution rule in different area. Conic can be used to describe the center part while cubic curve can be employed to depict the edge part. Also, parameters in the on-line wear calculation model of figure control system are regressed. The regressed results conform very well to general principles of roll wear and could be applied in on-line wear prediction.
