摘要

宝钢股份特钢分公司合金棒材生产线在节能轧制过程中（低于正常轧制温度80~150℃），因H5轧机齿轮箱出现异常振动而影响降温轧制工艺的实施。本文通过对H5轧机齿轮箱振动特性的实测诊断，结合有限元计算分析确定了齿轮箱发生异常振动的原因，并提出通过齿轮箱箱体加筋提高刚度以抑制其振动的措施。现场使用表明，H5轧机齿轮箱箱体加筋后，其异常振动得到有效抑制，确保了该节能降耗轧制工艺的实现。

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.
