Design of Manufacture Process of Slight-stretch Reducing Mill with Centralized Differential Drive System(Part Ⅱ)

Two drive types are used for the slight-stretch reducing mill, namely the individual drive(for each individual roll stand)and the centralized differential drive. Briefed in the paper is the design of manufacture process of the slight-stretch reducing mill. Detailed are the main aspects of the said mill, covering the basic theory of the manufacture process, the major technological calculation and the design method. Also described are the design improvements as made in practice over the recent years, and some rather applicable calculation methods for motor rpm of the slight-stretch reducing mill with centralized differential drive system.
