Research And Application Of Coiler Tension Control And Automatic Unloading Volumes

Efficient coiling as an important technical index to measure the pickling linecoiling performance, gradually attaches importance to the enterprises, which canimprove the production efficiency and is an important guarantee for improving the rateof finished products. On the basis of the actual situation of the cold-rolled sheet picklingline, the research and application of effective volume is introduced. In order to achieveefficient coiling for the purpose, to the actual production of restricting coiling efficiencyand volume of various factors and quality were analyzed, identified in order to reducethe tension fluctuation and realize automatic unloading trolley for the main projectsolution. To achieve efficient coiling around this purpose pickling solution, along thepreset, completed a large number of theoretical and practical works.Analysis and mathematical model of inverter vector control in tension control. Thetheory demonstrates the use of inverter closed-loop vector control feasibility to realizecoiling section of constant tension control. In the analysis of the commonly usedmethods of pickling strip tension control, the coiler constant tension control thought:Siemens6SE70series inverter drive based, closed-loop control by vector method, thevelocity saturation, torque limiting the coiler constant tension control.The reel rotation inertia friction compensation, detailed analysis and Study onfactors of large tension control effect, through the experimental determination of thecompensation amount of two factor method, difference compensation in settingparameters, further enhance the coiler constant tension control precision, reduce thetension fluctuation. To reduce the volume of quality problems with loose edge, shape,edge uneven and so on have appeared, efficient, high quality coiling.The unloading system automation, focuses on the theoretical and actual unifies,from the actual conditions of the site, combined with the existing process equipmentthrough the planning, feasibility analysis, parameters, experimental verification,program design, implementation of the transformation, commissioning several stepsforward, gradually complete the automation of coiler, automatic unloading function. Toreduce the equipment failure rate and the labor intensity of workers at the same time,improve the unloading speed and production efficiency, promote the efficient coiling.
