本文在对传统电动压下轧机压下系统进行简要介绍的基础上,对电动压下系统能力的提升、机构的完善进行了总结。鉴于液压AGC逐渐替代电动压下机构的趋势,总结了短行程液压AGC改造的要点,特别对长行程液压AGC改造方案的设计思路和要点进行了阐述,为电动压下轧机改造的设计工作和设备管理提供参考。 Based on the brief introduction of the traditional electric rolling mill reduction system, this paper summarizes the improvement of the electric reduction system and the improvement of the mechanism. In view of the trend that hydraulic AGC gradually replaces electric depressing mechanism, this paper summarizes the key points of short-stroke hydraulic AGC retrofit, especially describes the design ideas and key points of long stroke hydraulic AGC retrofit scheme, Management for reference.
