The acting force on the roll system of Sendzimir mill was analyzed using 3D FEM. The roll gap pressure distribution and the acting force between rolls S and O, rolls O and I, rolls O and J, rolls I and A, rolls I and B, as well as rolls J and B were analyzed. The results showed that the roll gap pre...

The deformation of slab with dogbone shape during the horizontal rolling process was simulated using FEM, and the influences of apical dislocation of dogbone on the slab spread as well as the minimum crop end loss and the lost width at slab head and tail were analyzed. The results show that with t...

Behavior of transversal crack notched on slab corner during verticalhorizontal rolling process was simulated by FEM. The crack tip stress in the whole rolling process was obtained. Influences of the friction coefficient, the initial crack size, the edger roll profile, and the groove fillet radii of...
