Micro-tension control system and method

ActiveCN103567230AGuaranteed tension control accuracyGeometry out-of-tolerance reductionMeasuring devicesTension/compression control deviceLoop controlClosed loop
The invention discloses a micro-tension control system and method. In the hot continuous rolling process, when a rolled piece enters a current machine frame and is stably bitten, the current machine frame is kept under speed control, speed control of main motors of machine frames on the upstream of the current machine frame is switched to constant torque control, on the basis, the torque and the rolling force of a main motor of the current machine frame are sampled to calculate the initial length of a rolling force arm, and the tension measurement calculating accuracy is improved. Each machine frame is provided with a pressure measuring head device to directly detect the rolling force, and consideration is given to the situation that the length of the rolling force arm is changed along with changes of the rolling force. Tension between the machine frames is obtained in real time through tension calculating models to form micro-tension closed-loop control to adjust the speeds of the machine frames so as to correct the tension deviations between the machine frames. As for a serial type universal rolling mill, the speed of the E machine frame serves as a standard, the rolling speed of the E machine frame is kept unchanged while speed set values of the other machine frames are adjusted, and real-time control is carried out on dynamic instantaneous values of the tension difference of the E machine frame before and after the adjustment process to guarantee micro-tension rolling of series universal rolling.
