heavy rail

基本解釋

The high quality heavy rail must be produced by high precision rolling technology. The conventional technology of 2-H mill adopted in our country is difficult to produced it.

In heavy rail rolling by universal mill,a simplified 3-dimention geometrical model has been built firstly. The kinematically admissible velocity field of the web,head and base of rail have been determined respectively,moreover the corresponding shear strain rate have been also obtained.
