Casting Mill Housing of 13060-6 Four-Roll Reversible Cold-Rolling Mill;

A hybrid method was proposed based on the combination of parameter sensitivity analysis and sequential optimization,a parameter model for 550 mill housing was established,and the dimensions were optimized with ANSYS,where minimizing volume was considered as the first objective function.

Facing to the huge size,complicated shape and high processing precision of mill housing and relying on the knife tool processing modification and the present machining capacity the suitable measurements are taken and the mill housing is perfectly manufactured.

Analysis of ruggedness rigidity and vibration for 2150 hot tandem mill frame;

Analysis of mechanical behavior of mill frame based on finite element method

Aimed at the vibration problem of 1700 four rollers strip mill,by using the large FEM software,structure analysis model of mill frame was established;and the natural frequency and the vibration models which are easily be excited were obtained.

Modelling study of the elastic deformation for 4-h mill;

This paper was to discuss the elastic deformation of rollers and interaction between work rollers and the strip during the roller milling process of a 4-h mill,by analyzing stress and deformation of rollers,put forwards a concise and practicable mathematic model of roller gap's shape,which resulted from some relevant factors,such as rolling pressure,bending force and so on.
