72” 4-High 2000 HP Cold Mill
The Application
Norandal USA, a manufacturer of light and
medium gauge aluminum foils used in the
packaging and automotive industry needed a
major retrofit on their breakdown cold rolling
mill.
Shape control for the continuous cast coils
needed improvement, and because of this,
production levels were limited. PCT
Engineered Systems, LLC was subcontracted
by Mannesmann Demag, an international mill
equipment manufacturer, to provide the PLC
control and operator stations, as well as the
mechanical and electrical installation for the project. Mannesmann Demag chose PCT
because of a past partnership providing turnkey reconstruction management of an
aluminum cold mill after a fire. Additionally, Norandal USA
directly contracted with PCT to
provide a new digital drive system for the cold rolling mill.
The PCT Solution
PCT Engineered Systems worked with
Mannesmann Demag and Norandal USA to
increase the mill’s productivity by improving
shape control and reducing between-coil time.
Shape control, a major concern for Norandal
USA, was improved by providing the following:
• A new hydraulic gauge control system
•
A new work roll bending scheme
•
New entry bridle equipment
• Upgraded flatness and spray controls
• An ABB shape roll
