在国内首创的不锈钢冷热轧带钢三机架连轧连退酸洗生产线中,根据产线的工艺控制要求,对不同区域的设备采用了包括闭环附加速度控制、开环转矩控制、闭环转矩控制等在内的多种张力控制模式,在严格保证张力控制精度的前提下最大程度精简了设备投入成本,同时针对性地应用了动态惯量补偿、速度补偿、传动速比修正、卷取张力锥度控制等多种优化手段,极大提高了产线运行中带钢张力的动态稳定性和可靠性。产线投产以来运行情况良好,满足了用户需求。
In China’s first stainless steel hot and cold strip mill triple tandem pickling pickling production line, according to process control requirements of the production line, the use of different regions of the equipment, including closed-loop additional speed control, open-loop torque control, closed-loop Torque control, including a variety of tension control mode, strictly under the premise of ensuring tension control accuracy equipment investment costs to the greatest extent streamlined, while the targeted application of dynamic inertia compensation, speed compensation, transmission speed correction, coiling Tension taper control and other optimization methods, which greatly improves the dynamic stability and reliability of the strip tension in the production line operation. Since the production line put into operation well, to meet the needs of users.
