Abstract
The sticking during hot strip rolling of ferritic stainless steel is evaluated using a tribo-simulator developed by the authors. The experiments of sliding rolling with an emulsion of Colza oil are carried out changing rolling conditions of rolling speed and rolling reduction using specimens of SUS430 and rolls with HSS (High Speed Steel). From these experimental results, it is confirmed that the sticking during strip rolling of ferritic stainless steel can be evaluated using the tribo-simulator. Then, the effects of S additive on the sticking are investigated. The experiments are carried out using emulsions of Colza oils with S additive contents of 20, 30, 50 and 80%. The limitation reduction when occurring the sticking increases with increasing S additive content.
