This paper elaborates the application of fluid innovation technology in the copper rolling mill, the backwashing filtering system and plus-minus bowed roller smooth transition system. The backwashing filtering system has a great flow filtering function which can make the filtering accuracy to reach 0. 5-5 μm and solid-state slag content after filtering to decrease by ≤10 mg/L.%针对铜带轧机大多采用的板式过滤机过滤精度低、易受污物堵塞等缺陷及传统的液压正负弯辊液压控制系统中正负弯辊切换时有时间差和过渡死区的问题,本文采用反冲洗滤系统,过滤流量大,过滤精度可以达到0.5～5μm,过滤后固体渣含量≤10 mg/L；采用的正负弯辊平滑过渡系统,通过电气操作杆实现弯辊力的快速、连续调节,消除了正负弯辊切换的时间差和过渡死区,且操作简便,可靠性高,提高了带材的表面质量,带材板形良好.
