Development for the Optimization Technique of the Coiling Tension in Degreasing Unit
As to the production of degreasing unit, fully integrated with the equipment and technological features of the line, the approach for the setting of coiling tension was changed, which was mainly tabular method in the past. Under the new idea, the degreasing process was closely integrated with the bell-type annealing for the first time. Then, to minimize the severity of stick breaks was set as the objective function, and no loose coil and no heart-shaped coil is took as the constraint condition. On these bases, a new comprehensive optimization model for the setting of coiling tension in degreasing unit was put forward. The relation between coiling tension and coil radius was obtained, which was a quadratic curve. This simple and practical technology can make the distribution of internal stress of coil more reasonable, and reduce the incidence of stick breaks, loose coil and heart-shaped coil defects effectively and improve production efficiency, quality and the metal yield.
