BLUESCOPE Steel Australia has chosen industrial automation group, Rockwell Automation , to provide a total turnkey control system for the paint line at the company's new Western Sydney Colorbond Centre.
Scheduled for completion by end-2006, and fully commissioned by March 2007, the new Colorbond processing facility represents a significant investment by BlueScope Steel in Australian manufacturing.
A Rockwell Automation Integrated Architecture-based control system - comprising Allen-Bradley ControlLogix and GuardLogix controllers, PowerFlex 700 AC drives, EtherNet/IP, DeviceNet, ControlNet communications, RSViewSE human-machine interface (HMI) and distributed I/O - will be used across the facility.
The ability to provide this fully engineered tailored control solution, in what was an iterative design process, ensured Rockwell Automation's involvement in the collaborative development.
The paint line's sophisticated web materials handling process requires over 90 drives and demands reliable drive performance with precision speed and torque control. This is met by the advanced Allen-Bradley PowerFlex 700 drive platform.
"Synchronisation of all drives is imperative to avoid product damage and costly downtime,” said Mark Curci, BlueScope Steel Lead Electrical Engineer. “Rockwell Automation provided the ideal drives solution by designing a dependable easy-to-use system."
In a process that requires routine operator access, safety control - associated with machine guarding, gate-latching and machine lock-down safety systems - was an overriding design consideration.
"Safety is the number-one priority in all BlueScope Steel designs," said Mr Curci.
The paint line's Logix-based control solution employs the Allen-Bradley GuardLogix controller to provide integrated 'safety-plus-standard' control within the one platform.
"The fully integrated control system will allow for faster implementation and provide design flexibility," said Mr Curci.
