A method for controlling a roller line, preferably a cold roller line, which has one or more roller stands each with two working rollers, which form a roller gap, through which a roller band is transportable. One or both working rollers can shift relative to the other, so that the roller gap is adjustable. The method includes making available a reference speed, which is a parameter for controlling the roller line, measurement of speed of the roller band before the inlet into the roller gap, measurement of the thickness of the roller band before the inlet into the roller gap, and adjustment of the roller gap of one or more roller frames in the roller line on the basis of measured speed and thickness before the inlet into the roller gap as well as the reference speed.

A device for cooling rolled stock, preferably for cooling during cold rolling, including a nozzle for applying a cooling medium to the rolled stock, wherein a cooling chamber that is in fluid communication with the nozzle and extends substantially parallel to the strip running plane is provided for applying the cooling medium to the rolled stock.

The invention relates to a method for hot-dip coating hot-rolled steel strip, during which the steel strip passes through a pickling station, a rinsing station, a drying station, a heating furnace and then through a molten bath. The final thickness and the thickness tolerance of the hot-dip coated steel strip are achieved by a controlled thickness reduction in a roll stand in the process line. The achievement of the finished thickness is controlled by at least one thickness measuring unit at the outlet of the roll stand, and deviations upward or downward therefrom are fed back in the form of an actuating signal for actuating the roll stand in order to appropriately increase or decrease the thickness reduction. The invention also relates to an installation for producing a steel strip of the aforementioned type.

An apparatus for cleaning cylinders () and/or rolls (), e.g., working rolls () in a rolling stand, which are used for producing a rolled stock () such as strips or slabs, in which a liquid is sprayed onto the cylinders () at high pressure through several nozzles D-Dn, a number of nozzles (D-Dn) are stationary arranged in and/or on a nozzle beam (), at least one on-off valve is associated with each nozzle (D-Dn), and one or several nozzle(s) (D-Dn) are sequentially switched on and off one after another starting from one end of the nozzle beam.

The invention relates to a method for straightening a metal strip () which is guided in the direction of transportation (R) through a straightening machine () and is straightened. In the straightening device (), the metal strip () is impinged upon by a straightening force (F) which is applied by a plurality of straightening rollers () in the direction (N) which is perpendicular to the surface of the metal strip (). According to the invention, prior to the metal strip () entering into the straightening machine (), the thickness (d) of the metal strip () is determined and the position (a) of the straightening rollers () in the direction (N) which is perpendicular to the surface of the metal strip () is taken into account according to the determined thickness (d).

The invention relates to a method and a device for treating surfaces of metallic strip material (), especially for pickling rolled material, in a treatment channel (), with a pickling medium () containing acid. Jets () are set in the direction in which the strip is transported () at the entrance to the channel () and in the opposite direction that in which the strip is transported at the exit of the channel (). The aim of the invention is to produce a closed liquid film with some turbulence on the surface of the strip. Said film should be maintained as far as the exit () of the channel. To this end, additional jets () between the channel entrance () and the channel exit () are oriented in the opposite direction to the direction in which the strip is transported () and the pickling medium () is further delayed in flowing out at the channel exit () by mechanical resistance devices () situated in the path of the transport channel ().

The invention relates to a method for tension levelling a cold-rolled strip, whereby the strip passes through a series of break rolls and a series of traction rolls and in the course of its extension is subjected to traction between the two series of rolls. The strip is bent under traction in a series of high-traction rolls, located between the brake roll and the traction roll series, in order to increase the degree of levelling. To achieve this, the series of high-traction rolls between the brake and the traction rolls has at least two traction rolls for generating the strip traction and bending operation.
