Upgrade of foil-rolling mill C3-2.
The JSC ASC specialists have completed a total redesign of foil-rolling mill C3-2 at RUSAL SAYANAL plant. The installation and commissioning works were anteceded by execution of design, procurement, manufacturing and testing of equipment all throughout the year 2024.
The upgrade activities included:
- • Replacement of high- and low-pressure hydraulic stations, hydraulic and pneumatic control panels with sensors and valves, pipelines.
- • Replacement of roll cooling manifolds, control and shut-off valves, sensors and impulse lines of the lubricant coolant system.
- • Replacement of bending hydraulic cylinders.
- • Replacement of pneumatic system for blowing off the lubricant coolant residue from the strip.
- • Replacement of pneumatic system for a smoothing roll.
- • Installation of a shape meter roll.
- • Replacement of automation cabinets, auxiliary electric loads, UPS, process visualization stations.
- • Development and implementation of TIA-PORTAL-based process control software, including the mill speed control system, automatic gauge control system, automatic flatness control system.
- • Development and implementation of CASCADE-based process visualization software, including the client-server, hot redundancy and data sheet production functionality.
- • Replacement of local and main control panels.
- • Partial replacement of cable products, instrumentation, control and automation equipment of the mill.
- • Installation of CCTV system.
- • Replacement of system for access to the mill equipment through existing gates.
- • Installation of mill parameter archiving system, based on IBA PDA software.
JSC ASC has implemented its own system for automatic flatness control of the strip, which operates in conjunction with shape meter system PSM-2000 (the South Korea). The control system is built on basis of “SIEMENS” equipment and the Russian scada-system “CASCADE”. Now the customer has the ability to monitor the flatness of manufactured products and promptly adjust it, using the systems that already exist on the mill.
