  • Patent number: 8069695
    Abstract: A system and method for cleaning the work rolls of a multi-roll leveler. The system includes a roll cleaning drive system for driving one or both of a set of upper and lower work rolls against a cleaning pad placed therebetween. The roll cleaning drive system is disengageable with the work rolls to be driven thereby. The upper and lower work rolls are driven in opposite rotational directions so as not to eject the cleaning pad from the leveler. The rotational direction of the upper and lower work rolls may be periodically reversed to produce a scrubbing action on the work rolls.

    Abstract: A method and a lubricant application device for regulating the flatness and/or roughness of a metal strip in the outlet of a cold rolling stand by suitable metering of the amount of at least one lubricant per unit time applied to the metal strip in the inlet of the cold rolling stand. The applied amount of lubricant is metered in the form of a quantitative distribution over the width of the metal strip per unit time according to a detected control deviation between an actual and a desired flatness distribution over the width of the metal strip in the outlet of the cold rolling stand or a control deviation between an actual and a desired roughness distribution over the width of the metal strip in the outlet of the cold rolling stand or a combination of the two control deviations.

  • Publication number: 20100089112
    Abstract: (EN) The present invention relates to a device for cooling a working roll (1, 2) belonging to a rolling stand used for rolling a long or flat product (3), characterized in that it comprises a cooling head in the form of a box section (6A, 6B) that is sealed except along a front face (42) lying a short distance from said roll (1, 2), and in which face a plurality of nozzles (41) has been machined or positioned in a determined pattern, said box section (6A, 6B) being concave and cylindrical at its front face (42). The box section (6A, 6B) is also fitted with transverse (5, 7) and lateral (8) plates which collaborate with the front face (42) of the box section so as to control the flow of cooling liquid and confine said liquid in the form of a highly turbulent flow. This then yields optimal cooling of the roll both in terms of the uniformity of the cooling across the surface thereof and in terms of the reduction in temperature as a result of the turbulent effect created.
