为满足国内大型宽厚板轧机的技术改造和建设,西安重型机械研究所研制出新型干油液压压下装置(见封底),并于1988年元月8日通过技术鉴定。试验证明:本装置适用于大中型中厚板热轧机的轧辊定位,其结构和密封等均紧凑良好,静动态性能指标相当于国外80年代初同类设备的。所使用的检测元件都是国产的,经济性好。其位置控制系统的定位精度小于10μm,响应频带宽大于10Hz。
In order to meet the technological transformation and construction of large-format heavy plate mill in China, Xi’an Heavy Machinery Research Institute developed a new type of dry-oil hydraulic pressure reduction device (see back cover) and passed technical appraisal on January 8, 1988. The test proves: The device is suitable for the roller positioning of large and medium-sized plate hot rolling mills. The structure and sealing of the device are compact and good, and the static and dynamic performance indexes are equivalent to those of similar equipment in the early 1980s. The detection components used are domestic, good economy. The position control system positioning accuracy of less than 10μm, response frequency bandwidth greater than 10Hz.
