This paper introduces the numerical simulations of the blade rolling technology by MSC/superform of American MARC Co.

the technology of roll is the method of using the rolling way to produce the part and is alsothe important component of the advanced manufacturing technology .

This paper introduces horizontal shaft of vertical mill is changed into statically indeterminate beam supported by three points used of virtual constraint in the reforming process of RE1 vertical mill transmission device of 500mm hot strip mill production line in Laiwu iron and steel general works,thus the strength,rigidity and transmission stability of this mill are increased.

The research on the process of flexible rolling for shaft forgings and experiment;

The flexible rolling process is suitable for forming of the step shaft forgings,with the advantages such as short development period,lower cost and high flexibility.

Effect of backup roll driven in six-high mill on strip shape;

Finite element analysis of the rigidity characteristics of a six-high mill;

Rolls' deformation and roll force distribution between rolls on a six-high mill are calculated by influence function method to study the influence of single-taper crowned intermediate rolls on the roll force distribution between rolls and transverse distribution of strip thickness.
