Abstract (en)
[origin: EP1647604A2] The procedure, in which steel or aluminium strip (3) passes round upper and lower rollers in a heating or cooling chamber (1), uses a computer (100) to provide real-time calculations of the heat profile of the rollers and the maximum admissible temperature of the metal strip for the most critical rollers. The calculations are effected by reference to at least one integrated physical heat exchange model including conduction exchanges between the strip and rollers, and strip heaters (4) are adjusted accordingly.
