一台采用最新工艺的12辊冷轧机,最近在西德菲林根·施威宁恩县黑林山冶金厂投入生产。此轧机的特点是装备了约瑟夫·夫罗宁轧机制造公司最近研制成功的直接液压压下装置。轧机通过由伺服阀控制的、独立的高压液压控制系统,使反应时间达到最短,压下行程最小,从而获得最严格的带钢公差。 1.液压压下调节新轧机装备的直接液压压下装置能使带钢保持最小的允许误差。伺服阀通过带钢厚度自动调节装置进行控制。带钢厚度调节装置的主要部件是定位调节器,它能在闭路调
A 12-roll cold-rolling mill using the latest technology was recently put into operation at the Black Forest Metallurgical Plant in West Fellingen Schweringen. The mill is equipped with a direct hydraulic press recently developed by Joseph Ferronin Manufacturing Company. Mill through the servo valve control, independent high-pressure hydraulic control system, so that the reaction time to minimize the minimum stroke down to get the most stringent strip tolerances. 1. Hydraulic pressure regulation The direct hydraulic pressure reduction device for new mill equipment allows the strip to be kept to a minimum allowable error. Servo valve through strip thickness automatic adjustment device to control. The main part of the strip thickness control is the positioner, which can be closed-loop
