Abstract：The abnormal vibration of H5 mill’s gear box has influenced the implementation of the energy-saving process(80~150℃ lower than normal rolling temperature) in the alloy bar production line of special steel branch, Baosteel limited company. The reasons of the abnormal vibration have been determined by experiment and ANSYS finite element analysis, and corresponding measures have been provided. The rigidity of the gear box has improved by reinforcing ribs. By applying the reinforced gear box, the abnormal vibration has been effectively inhibited and the implementation of the energy-saving process has been guaranteed.
