hydraulically operated stopper(rod: Steel flow from the tundish to the mold is regulated with a hydraulically operated stopper rod. 中间包至结晶器的钢水流量使用液压塞棒调节。)
"DYNAFLEX" hydraulic oscillator(【技】该振动装置由奥钢联在林茨的研究设计集团 (the Research and Design Group of VAI in Linz, Austria) 研制成功,突破了传统结晶器振动的四连杆型机构,转而采用了板簧式振动系统。其特点是取消了轴承传动,基本上实现了无磨损,维修方便,运动精度高,使用性能稳定,可在线改变振幅和振频,优化了振动参数,延长了使用寿命,提高了铸坯表面质量。)
hydraulically operated press(An hydraulically operated press of 3000 tonnes' capacity is used to make stainless steel tubes with bores from 25 to 165 mm and outside diameters of up to 190mm. 一台 3000 吨位的液压机用于生产内径 25 ~ 165mm, 外径最大为 190mm 的不锈钢管。)
