CONTROL METHOD FOR A PRODUCTION LINE FOR ROLLING HOT-ROLLED METAL STRIPS DISPOSED UPSTREAM OF A COOLING STRETCH

摘要

According to a method, initial temperatures (T 1 ) of strip points ( 101 ) are detected when the hot-rolled strip ( 6 ) is fed to the production line. The strip points ( 101 ) are monitored on their way through the production line. The hot-rolled strip ( 6 ) is subjected to temperature influences (delta T) in the production line ( 3 ). The strip points ( 101 ), the initial temperatures (T 1 ), the monitored values (W(t)) and the temperature influences (delta T) are supplied to a model ( 9 ) for the production line ( 3 ). The model ( 9 ) determines expected actual temperatures (T 2 ) of the strip points ( 101 ) in real time and allocates them to the strip points as the new actual temperatures (T 2 ).
