18、用。軋機(jī)的壓下控制（AGC）以及類似的其他控制（AWC、AJC）等是軋機(jī)中的關(guān)鍵控制，這類液壓缸的品質(zhì)直接影響到軋制品的質(zhì)量。低的液壓缸動靜態(tài)摩擦力是減小系統(tǒng)控制死區(qū)的基本保證，而閉環(huán)系統(tǒng)的高壓力脈動以及高頻響帶來的高速度對液壓缸的材料和加工水平、以及結(jié)構(gòu)合理性提出了挑戰(zhàn)，因此基于CDH2型技術(shù)開發(fā)的這類產(chǎn)品滿足了現(xiàn)代軋機(jī)高性能的要求。3714th 15th January 2004, Bosch Rexroth in ChinaHydraulic cylinders BRI-ZYProximity switch接近開關(guān)3814th 15th January 2004, Bosch Rexro
