FIELD: process engineering.
SUBSTANCE: invention aims at brining brush at constant force to working and/or support rolls or rolling mill stand for aluminium hot-rolling. Aforesaid brush is mounted on rotary lever and driven to fit the roll. Constant force applied to brush, at various roll diametres and operating positions and varying brush wear, is allowed by driving device that comprises at least one control element arranged on rotary lever and articulated with the latter via appropriate force transfer element. Proceeding from preset force F0 for continuous control of brush bringing force, control circuit allow continuous control of aforesaid force by appropriated actuating mechanism. Note that, to this end, control device is used to control deviation angle of control element relative to rotary lever.
EFFECT: higher efficiency.
