Abstract To meet the demands of producing round and square billet for billet continuous mill and raise the usage of oval and round passes, a new method, “ovalrounddiamondsquare” passes, is utilized to roll square billets. FEM and industrial rolling test are used to study the deformation behavior of square billet and round billet in diamond and square passes. The deformation for different rolling processes is compared. The results show that the deformation for diamond pass roll round billet is more uniform, the dimensional precision of head and tail of workpiece is higher, and the wear of diamond pass is more uniform. The results are helpful to rationally developing rolling procedure for intermediate round pass to roll square billet.
