13000mm 但由于负载相对较小 按照活塞杆的压杆稳定性计算 CDH2的标准产品可以扩展到这种应用场合 现代的轧机技术对换棍缸提出了定位精确和快速的新的要求 CDH2液压缸具有好的轴心定位能力和支撑性能 且可以带二端接近开关或长行程的CIMS位置传感器 1 所以被广泛使用 轧机的压下控制 AGC 以及类似的其他控制 AWC AJC 等是轧机中的关键控制 这类液压缸的品质直接影响到轧制品的质量 低的液压缸动静态摩擦力是减小系统控制死区的基本保证 而闭环系统的高压力脉动以及高频响带来的高速度对液压缸的材料和加工水平 以及结构合理性提出了挑战 因此基于CDH2型技术开发的这类产品满足了现代轧机高性能的要求 38 14th 15thJanuary2004 BoschRexrothinChina HydrauliccylindersBRI ZYProximityswitch接近开关 39
