This paper deals with the method to delay occurring polygonal deformation phenomena of rolls in a reversible hot plate leveler of the steel-making machine analytically. The plates leveled by rolls with polygonal deformation become so called defective products because the profile of deformed roll is transferred to the surface of plate. If it is possible to prevent or delay occurring polygonal deformation phenomena, users can save costs to change work rolls. The authors analyzed a simple model theoretically, regarding the polygonal deformation phenomena as unstable vibrations of the hot leveler system caused by time retardation accompanied by wear on the surfaces of rolls. The authors also confirmed that it is possible to delay occurring polygonal deformation phenomena by changing operation speed of work rolls alternately.
