JJRS excellent Annealing Pickling Line

0.16~0.8mm*700~1270mm 240,000TPY

In line model mode, the modeling supervisory system provides speed, tension, zone temperature and damper setpoints plus other outputs based on the current strip gauge, width and temper. The supervisory system calculates and optimizes controller setpoints and uses feedback and feedforward to modify the various algorithms. For example, if a newly loaded coil is wider and heavier than the current strip, the modeling database predicts (from weld detectors) when the new strip will enter the heating furnace. It therefore increases furnace zone temperature setpoints in advance, but also increases line speed to ensure that the current strip does not overheat. When the current strip exits the hot furnaces, the speed is reduced to allow the new heavier strip a longer time in the heating furnace.
