Abstract
A multi-stand hot strip rolling mill has a pinch roll assembly downstream of the last stand and before the coiler and a shapemeter roll is located between the last stand and the pinch roll assembly so as to engage with the strip.
Claims3
The combination of a multi-stand hot strip rolling mill;
- a shapemeter roll located downstream of the last stand of the rolling mill, said roll being movable between a first position in which it engages with metal strip leaving the last stand to detect variation in tension across the width of the strip and a second position in which it is spaced from metal strip leaving the last stand;
- and a pinch roll assembly located downstream of the shapemeter roll, said assembly comprising a pair of driven rolls which are movable between a first position in which the rolls engage opposite faces of the strip to apply tension to the portion of the strip extending from the last stand of the mill to the pinch rolls and a second position in which the strip is permitted to pass between the rolls without having tension applied thereto.
