Abstract
Rolls of a strip line are cleaned by directing jets of a cleaning liquid thereagainst from nozzles which are mounted so that their distances from the roll to be cleaned can be set or controlled.
Claims18
A method of cleaning a roll for processing strip in a mill line for production of metal strip, said method comprising the steps of:
- (a) training a jet of a cleaning liquid from at least one nozzle against a surface of said roll to be cleaned;
- (b) displacing said nozzle back and forth along said roll while rotating said roll and said jet impacts said surface;
- (c) controlling a spacing between said nozzle and said surface and regulating said spacing during the back and forth displacement of said nozzle to maintain a value of said spacing;
- and
- (d) controlling a back and forth traverse speed of said nozzle as a function of at least one parameter selected from the group which consists of:
- strip speed;
- strip material and strip surface.

An apparatus for cleaning a roll for processing strip in a mill line for production of metal strip, said apparatus comprising:
- at least one nozzle training a jet of a cleaning liquid against a surface of said roll to be cleaned;
- means for displacing said nozzle back and forth along said roll while rotating said roll and while said jet impacts said surface;
- and
- means for controlling a spacing between said nozzle and said surface and regulating said spacing during the back and forth displacement of said nozzle to maintain a value of said spacing, said means for displacing including a carriage displaceable on rails parallel to said roll, said means for controlling including at least one piston-and-cylinder arrangement connected to said nozzle for controlling said spacing.
