Extensive treatment for a production line


A pre-treatment line was needed to extend the current production line of a rolled zinc manufacturer based in Spain. To control the cleaning and pre-treatment of its phosphate coating line, the installed system would process raw coils through a rigorous cleaning and finishing treatment section, where quality standards are very high and a consistent colour essential.

 A totally integrated electrical control system would offer full control of the cleaning and finishing treatment. Iconsys chose Siemens drives and controls technologies (Siemens IA & DT). The electrical equipment supplied included AC variable speed drives, a PLC, control gear, SCADA and variable speed drive AC motors of Siemens IA & DT manufacture.
