Coupling of lateral and torsional vibration for the spindle of a CSP mill;

The problems of universal shaft in roughing and intermediate mill are analyzed.

The two problems were as follows: The universal shafts were frequently broken,which was caused by the original design for the shaft's safety device;the leveler's roller could not be reinstalled smoothly,which was caused by the inaccurate location of the clamping device when changing rollers.
