西德的Josef FRhling公司最新推出一种12辊可逆冷轧机。这种轧机采用直接液压压下装置,即采用了控制高压油路的伺服阀,使响应时间和行程极短,从而轧出高精度公差的板带。 该轧机装有测量和控制板带平直度的装置,以压下装置中间辊弯辊装置及液压水平移动辊装置调整板带的平直度,还采用了区域冷却法来进行辊型调整。 Josef FRhling, West Germany, recently introduced a 12-roll reversing cold rolling mill. The mill uses a direct hydraulic depressor, a servo valve that controls high-pressure oil lines, to provide response time and travel very short, thus rolling out high-precision tolerance plates. The mill is equipped with a device for measuring and controlling the flatness of the strip, adjusting the flatness of the strip with the intermediate roll bending device of the pressing device and the hydraulic horizontal moving roll device, and the area cooling method is also used for roll profile adjustment.
