Abstract
A rolling mill (1) for rolling metal strip has provision for applying discrete levels of liquid coolant to the strip and the temperature (te) of the strip leaving the mill is compared with a target temperature (ts) and the temperature (Te) the incoming workpiece is compared with a target temperature (Ts). The difference signals are employed to control the levels of liquid coolant and the rolling speed so that the exit temperature remains substantially equal to the target exit temperature.
