Problems solved by technology
[0011] Considering that there are many reasons for the tension fluctuation, such as the slippage of the tension roller, the change of the friction damping of the conveying roller, the change of the catenary curve of the strip steel, the influence of the deviation correction device, the change of the internal force of the strip steel at different temperatures, etc. will appear at times, their influence on tension is nonlinear, and it is difficult to establish a mathematical model to solve the problem of mutual influence of tension fluctuations between multiple connected tension segments

The invention discloses a tension control method of a cold rolling continuous annealing unit, comprising the following steps: S1: respectively calculating the tension deviation ΔTi at the time s above each tension control section i; S2: calculating the tension deviation ΔTi at the time s above each tension control section i ΔTi is sent to the controller and the tension regulator respectively, and the actual additional speed at the time s on the tension control section i is sent to the controller; S3: Calculate the additional speed that needs to be output at the time s+1 on each tension control section i; S4: Perform speed correction on tension control section i according to additional speed Vi(s), Vi(s+1); S5: uniformly adjust the strip tension of multiple tension control sections i according to the corrected additional speed, repeat S3-S5, Until the tension deviation ΔTi tends to 0. The present invention improves the tension stability of the cold-rolling continuous annealing unit by reducing the overall tension deviation of the cold-rolling continuous annealing unit and reducing the mutual influence between tension sections.
Description
technical field [0001] The invention relates to the technical field of metallurgy automation, in particular to a tension control method and system for a cold rolling continuous annealing unit. Background technique [0002] The cold rolling continuous annealing unit generally consists of three sections: the entrance section, the process section and the exit section. [0003] The entrance section is mainly composed of steel coil trolley, uncoiler, pinch roller, slitting shear, welding machine, tension roller and looper and other equipment. The process section is mainly composed of cleaning, continuous annealing, cooling, re-cleaning, coating process, drying treatment and other process equipment and tension rollers. The export section is composed of looper, tension leveler, tempering machine, slitting shear, coiler and coil unloading trolley and other equipment. [0004] In the entrance section, the cold-rolled steel coil is sent to the uncoiler by the steel coil trolley, and...
