Three Stand Hot Mill Upgrade

The Application

A large aluminum manufacturer was struggling to

maintain the obsolete control equipment on their only

hot mill. The mill, which normally produces over a

million pounds of aluminum per day, experienced two

weeks of down-time during the summer of 1996

because of breakdowns related to this equipment. A

new control system was needed to provide

dependable operation and minimal disruption to

production during installation.

The PCT Solution

PCT Engineered Systems was asked to design,

program, assemble and install a new system for

control of the mill drives, winders and shear, as well

as providing an interface to the Mannesmann

Demag MARAS gauge control system being

installed. The PCT control system utilized new

digital control boards connected to the existing mill

drive SCR’s thereby leaving the high current

components (SCR stacks, bus work and

overcurrent protection) in place.

The control system’s design and the fact that new

standard Reliance parts are easily reordered

instead of having to be custom built, greatly reduced the cost of the new equipment and allowed

more efficient maintenance of the equipment.

PCT scheduled on-site project work around the customer’s scheduled shutdowns to reduce the

impact on production. The entire upgrade was completed during two separate two-week outages.
