Embodiment Construction

[0021] The figure is divided into two parts 1a and 1b. These two parts show the mill roll 1 supported by bearings 2 . The cleaning device 3 can move towards the roller 1 parallel to the axis 5 of the roller 1 under the action of the jack 4 . The cleaning device 3 comprises two supports 31 and 32 which each ensure the supply of cleaning liquid to four nozzles 311 , 312 and 321 , 322 which are divided into A pair of nozzles and a second pair of nozzles are provided on each of said two supports 31 , 32 .

[0022] During the extended phase of the jack 4 shown in part 1a of said figure, the two first nozzles 311, 312 work and respectively clean the first zone 1-311 and the second zone 1-312 of the roll, said The two areas are juxtaposed. The second pair of nozzles 321, 322 are inactive.

[0023] During the retraction phase of the jack 4 shown in part 1b of the figure, the second pair of nozzles 321, 322 work and respectively clean the third zone 1-321 and the fourth zone 1-322 ...

Abstract

The present invention describes a device for cleaning a roll (1) of a steel strip conversion plant, which device is designed to move parallel to an axis (5) of said roll (1), comprising: at least an even number N (> 0) of parallel spray nozzles, said nozzles being perpendicular to the axis (5) of the roll, a first number N/2 of the nozzles (311, 312) being fixed to a first arm (31) of a supporting member (3) and a second number N/2 of nozzles (321, 322) being fixed to a second arm (32) of the supporting member (3), said supporting member (3) being coupled to an actuator (4), the actuator (4) having a travel of at least 1/N of the length of the roll (1).

Description

technical field [0001] The invention relates to the cleaning of rolls, such as back-up rolls or work rolls, of a rolling mill, especially a laminoir skin-pass, by means of a high-pressure jet. Background technique [0002] The leveling of the steel strip is a cold rolling operation with moderate elongation under the action of traction. Rolling mills capable of tempering operations are incorporated into many strip processing lines where they are mainly used for the following purposes: [0003] - Elimination of the elastic limit (palier élastique) of steel, thus resulting in better quality stampings later manufactured from steel strips; [0004] - Improve the flatness of the steel belt; [0005] - In order to improve the stamping tribology, embossing a special surface condition onto the steel strip. [0006] In some of their uses, the surface of the rolls of the temper mill may be contaminated with adherents which impair the surface quality of the steel strip. This is the ...
