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.

从生产率的观点出发，在铁素体系不锈钢的热轧中，防止轧辊粘着非常重要。但是，粘附的形成机理尚未充分阐明。因此，在这项工作中，使用摩擦模拟器进行了滚动实验。结果阐明了以下几点：与高强度钢相比，铁素体不锈钢更容易发生粘结。在铁素体不锈钢上，工作辊在咬合口处粘在热轧板上，然后工作辊在热轧板上向前移动。因此，可以认为热轧板的表层由于较大的摩擦剪切应力而断裂，因此，被卡住了该断裂层的工作辊在该钢板上进一步前进，从而形成缺陷，并累积有断裂的表层。
