Effect of Kinematic Tension Coefficient on Wall Thickness Variation for Tube/Pipe Rolled in a Reducing Mill

详细

We describe the results of a study of the longitudinal and circumferential variation in pipe/tube wall thickness as a function of kinematic tension coefficient for pipe/tube passing through three stands of a reduction mill. The study was performed via computer modeling using the DEFORM software. The variation in pipe/tube wall thickness and the mean wall thickness were found to decrease as the kinematic tension coefficient increased, as evidenced by the calculated dispersions, root mean square deviations, and coefficients of variation.
