Analysis of Roll Gap Pressure in Sendzimir Mill by FEM

YU Hailiang , LIU Xianghua , WANG Chao , Park Haedoo

钢铁研究学报(英文版)

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...

Influence of DogBone Apex on Shape During Slab Horizontal Rolling Process

YU Hailiang , LIU Xianghua , LI Changsheng , WANG Guodong

钢铁研究学报(英文版)

The deformation of slab with dogbone shape during the horizontal rolling process was simulated using FEM, and the influences of apical dislocation of dogbone 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 on Slab Corner During VH Rolling Process

YU Hailiang , LIU Xianghua , LI Changsheng , Y. Kusaba

钢铁研究学报(英文版)

The behavior of transversal cracks on the surface of the slab corner during vertical and horizontal (VH) rolling process with flat vertical roll and groove vertical roll was simulated by explicit dynamic finite element method. The closure and growth of crack and the contact pressure on surfaces of ...

Influence of Edge Rolling Reduction on PlateEdge Stress Distribution During Finish Rolling

YU Hailiang , LIU Xianghua , CHEN Liqing , LI Changsheng , ZHI Ying , LI Xinwen

钢铁研究学报(英文版)

Dimensions of one kind of stainless steel plate before finish rolling were obtained through analysis of the rough rolling processes by finite element method and updated geometrical method. The FE models of finish rolling process with a front edge roll were built, and influences of the edge rolling r...

Analysis of Crack Tip Stress of Transversal Crack on Slab Corner During VerticalHorizontal Rolling Process by FEM

YU Hailiang , LIU Xianghua , WANG Guodong

钢铁研究学报(英文版)

Behavior of transversal crack notched on slab corner during verticalhorizontal 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...
