由于板带轧制高速、连续、自动化的飞速发展,在轧机结构上发展的主要新特点之一,是采用全液压轧机,即采用液压压下系统代替传统的电动机-压下螺丝的压下系统,它不是简单的代替,而是利用液压压下具有的速度快、精度高、易控制等特点建立一套轧制厚度自动控制(AGC)系统,在六十年代后期至七十年代,各国兴建的板带轧机均相继采用液压轧机,尤其是冷轧机更为突出,以近年来国外板带轧机发展最快的日本
Due to the rapid development of strip rolling at high speed, continuous and automatic, one of the main new features developed in the structure of the rolling mill is the use of a full hydraulic mill, a hydraulic press system instead of a conventional electric motor - , It is not a simple replacement, but the use of hydraulic pressure has the characteristics of speed, high precision, easy to control and so on to establish a rolling thickness automatic control (AGC) system, in the late sixties to the seventies, all countries to build Of the strip mill have been used hydraulic rolling mill, especially the cold rolling mill is more prominent in recent years the rapid development of foreign plate mill Japan
