Strategy research on force setting of strip-switching process in continuous annealing furnace

This paper analysis the force between strip and roll in continuous annealing furnace at first, and make the research on the force setting of the strip-switching process after. Through the study, it indicates that the force setting is not that easily changing one force value to another. This adjustment is limited by both sides of the strip tension to avoid the slipping between the strip and roll. To solve this problem, the switching strategy which limits the difference between two adjacent setting forces is proposed.
