Slitting line control system anti-jamming with self diagnostic function of the metal coil cut into strips of various widths required, then a small strip harvest volumes for next process, is the transformer, motor industry and other metal band Precision cut timber necessary equipment. Slitting line is mainly composed of coil car, uncoiler, traction leveler, shearing, slitting machine, scrap winder, tension mechanism, winding machine, unloading device and other components. The production line fully consider the safety of man, to take protective measures to prevent misuse and reliable. The slitting line is composed of decoiler, crude school machine, fine school machine, slitting machine (two), rewinding machines, automatic straightening system. Using balloon-type compression, tension in different thicknesses to ensure a balanced tension. Main electrical control components and hydraulic components equipped with imported products have high working reliability; control system anti-interference ability, with self-diagnostic features to help quickly find the cause. Suitable for processing cold rolled and hot-rolled carbon steel, silicon steel, tinplate, stainless steel and surface coating as the various metal materials. In order to solve the tension and winding characteristics abrasions title topic, I technical team successfully developed a taper tension, anti-scratch tension mechanism control system. The production line is smooth and reliable, low noise, easy maintenance and reliable. Slitting line performance and technical parameters of the production line name slitting line (XH1700ZS6) use the unit for tinplate, galvanized iron, silicon steel, stainless steel, aluminum, steel and other coil slitting shear. The machine uses locking type or spacer double with a round shears. The main action of this production line are used hydraulic form, smooth and reliable operation, low noise, easy maintenance and reliable. EPC can also choose automatic edge control, to ensure orderly winding degree, especially for wide material winding.
