The Research On Coiling Vibration And Tension Distribution

Coiler is an important auxiliary equipment in the steel-rolling workshop and is extensive used in strip steel and wire stock manufacture. Coiler is a set of mechanical, electrical, hydraulic, control, transmission as one of the complex system, and work in the very poor environment. The functional states of coiler directly influence the productive power of the rolling mills, particularly of the tandem mills, and the product quality of strip. Therefore, research on reel vibration and tension distribution during the coiling is extraordinary necessary.Strip coiling is a quite complex deformation process. Before, people almost concentrated on reel radial pressure and internal stress calculation. But, researches on tension distribution were very less, which real impact the coiling shape of strip. In recent years, with increasing surface quality by users require on strip and increasingly fierce market competition, coiling technology was gradual attention by the domestic and international researcher.This paper first describe the type of cold-rolled coiler, technological features, structure and development, summary the coiler structure and working principles; Secondly, establish the reel vibration model, analysis the drum vibration and working conditions during the coiling process; Again, theoretical arithmetic different locations change of coiling radius along the axial, which influence the tension distribution. Use iteration method to calculating the coiling radius during coiling, and transverse distribution of tension stresses which in different circumstances plate crown, Finally, use ANSYS/LS-DYNA simulate the process of coiling. Proved the results accuracy by compare the simulation value with calculation value.
