FINITE ELEMENT ANALYSIS FOR MICROSTRUCTURE EVOLUTION IN HOT FINISHING ROLLING OF STEEL STRIPS Z.T. Wang1,D.Z. Li2,S.H. Zhang2,Z.D. Qu2 (1.Shenyang Ligong University, Shenyang 110168, China...:A computer model that describes the evolution of microstructures during the hot finishing rolling of SS400 steel has been proposed. It has been found that the microstructure strongly depends......
on research. The above research mostly focused on the one-wedge CWR. In recent years, some research has been focused on the multi-wedge cross wedge rolling (MCWR) process.

]. Asymmetric rolling can be achieved by two approaches: one is by rotating the top and bottom work rolls with different angular velocities where the diameters of both the rolls are the same; the other...;. With the combined forces including drawing, compressing and shearing, severe plastic deformation was obtained during the asymmetric rolling, promoting dynamic recrystallization at room temperature. Because......
Dynamic characteristics of cold rolling mill and strip based on flatness and thickness control in rolling processSUN Jian-liang(孙建亮)1, 2, PENG Yan(彭艳)1, 2, 3, LIU Hong-min(刘宏民)1, 2(1.

rolling, the sheets were firstly heat treated for 15 min at 673 K. The rolling experiments consisted of one rolling pass to different final thicknesses. The thickness reduction was 20%, 30% and 50... study is also focused on texture evolutions during intermediate and large strain hot rolling. When one pass rolling reduction reaches 30%, a double-peak type basal texture is formed mainly......
