along the hot-rolled strip width are unlikely causes of the occurrence of ridge-buckle defect we attempted to link ridge occurrence in hot rolled strips and to uneven roll-wear in the finishing mill. By collecting data of 40 consecutive schedules, we were able to determine that ridge formation in hot rolled strips is a common occurrence.

CATEGORY: ROLL SURFACE INDICATIONS TYPE: PEELING .

Peeling only occurs in hot strip mill applications and is typically limited to the early stands where the strip temperatures are the hottest. During rolling, the roll barrel surface in contact with the strip or bar is heated to a sufficiently high temperature so that on exiting the roll bite oxidation occurs.
