PHYSICAL MODELING OF EDGE ROLLING IN PLATE MILL WITH PLASTICINE

In the plate mill edge rolling is often used to increase yields by red ucing defective end shapes. In this study, the effect of process varia bles in edge rolling on the plane view pattern of the plate was examin ed by a physical modelling technique with plasticine model material. T he prime consideration was given to obtain information on the shape de fects of plate such as overlap, width shortage, crop length, bulging a nd buckling with respect to process variables which is difficult to ch eck in detail on the shop floor. The result provided valuable informat ion on optimal edge rolling process in spite of some limitation in phy sical similarity between plasticine and hot steel.
