19、被广泛使用。4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。14th 15th January 2004,Bosch Rexroth in ChinaHydraulic cylinders BRI-ZYProximity switch接近开关接近开关3814th 15th January 2004,Bosch
