Abstract
A method for coiling a metal strip that is heat-treated in a furnace immediately before coiling and fed to a coiler at an outlet speed, and then coiled at the coiler at an elevated temperature. The future outlet speed of the metal strip and the heat losses from the metal strip between the furnace and the coiler are calculated via a predictive model and the furnace is controlled by the predictive model such that the metal strip is coiled at a pre-defined temperature within a maximum deviation of +/−5° C.
