摘要

In hot rolling of ferritic stainless steels, prevention of sticking to rolls is very important from the viewpoint of productivity. However, the formation mechanism of the sticking has not been clarified sufficiently. Therefore, in this work, rolling experiments were carried out using a tribo-simulator. The results clarified the following points: Sticking occurs more easily on ferritic stainless steel than on high strength steel. On ferritic stainless steel, a work roll sticks with the hot-rolled sheet at the entrance of roll-bite, and the work roll then moves forward on the hot-rolled sheet. Therefore, it is thought that the surface layer of the hot-rolled sheet is fractured by large frictional shear stress, and the work roll stuck with the fractured layer advances further on the sheet, forming defects with an accumulated fractured surface layer. Lubrication with oil is effective for prevention of sticking between the work roll and the hot-rolled sheet.
