对液压控制辊缝的轧机的研制是于1966年开始的,当时建立了一个进行系统试验和部件寿命试验的液压实验室,并利用一个一百吨重的轧机机架和额定压力为1100吨的液压缸按设计尺寸建造了一台试验轧机,以测定液压控制辊缝的轧机的动力学特性。第一台液压控制辊缝的轧机已于1969年9月投入运转,至今为止,Davy—United和Lowey Robertson公司接受了三十套这种轧机机架的订货,其中二十一套已经交货了。
The development of the hydraulically controlled roll gap mill started in 1966 when a hydraulic laboratory for system testing and component life testing was established and a 100-ton mill stand and a 1,100-ton The hydraulic cylinder was designed with a pilot mill to measure the dynamic characteristics of a roll controlled hydraulically controlled roll gap. The first hydraulic controlled roll gap mill was put into operation in September 1969 and to date, Davy-United and Lowey Robertson have placed orders for thirty such rolling stands, of which twenty one have been delivered .
