Explicit Dynamic Fem Analysis Of Multipass Vertical-Horizontal Rolling, Hai-Liang Yu, Xiang-Hua Liu, Xian-Ming Zhao, Di Wu, Y Kusaba
Faculty of Engineering and Information Sciences - Papers: Part A
Three passes of plate rolling during vertical-horizontal rolling process are simulated with explicit dynamic finite element method and updating geometric method. The equivalent strain and stress fields, and shape change at the head and tail of slab during rolling are obtained. The calculated result of the shape at the head and tail of slab is in good agreement with the measured one. The explicit dynamic finite element method and updating geometric method can be used effectively to analyze the multipass vertical-horizontal (V-H) rolling process. © 2006 Central Iron and Steel Research Institute.

Behavior Of Transversal Crack On Slab Corner During V-H Rolling Process, Hai-Liang Yu, Xiang-Hua Liu, Chang-Sheng Li, Y Kusaba
Faculty of Engineering and Information Sciences - Papers: Part A
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 the crack in contacting zone between slab and roll during rolling process were analyzed. The results showed that during vertical rolling process, when the groove vertical roll is used, the maximum contact pressure on surfaces of the crack is 115 MPa, and the closure of crack is stable; when the flat vertical …
