Electrical control equipments of the whole line includes basic automation control system, AC drive system, auxiliary drive system, hydraulic screw down control system and HM interface, etc. and adopts the Profibus communicating network for insuring the advancement and reliability of the electrical control system. The communicating with the upper-class computer adopts the Ethernet.


The hot dip galvanized steel sheet to be cleaned will be immersed in the dissolved zinc pot after reduction annealing to make the surface adhere to a layer of zinc or zinc-aluminum alloy thin steel sheet to improve the corrosion resistance of the steel sheet.Hot dip galvanized steel is mainly used in construction, home appliances, automobiles, machinery, electronics, light industry and other industries.
