The bottom side of the steel strip (50) can be cooled by the cooling nozzles (23) or cooling tubes (23a) or the cooling slot (24) of the lower water tank (21b). The top side of the steel strip (50) can be cooled by the cooling nozzles (23) or cooling tubes (23a) or the cooling slot (24) of the upper water tank (21a).

A rolling mill includes a frame, at least one pair of working cylinders capable of defining the air gap of the strip to be rolled, as well at least one line for spraying a lubricant and/or coolant fluid, arranged next to the plane of the strip to be rolled. The line is rigidly connected to the frame via a hinged mechanical link, the mechanical link including a resilient unit forcing the line into at least one operational position, toward the plane of the strip, and allowing, in the event that a force on the line tends to separate the line, greater than a threshold value, the deformation of the resilient unit against the return force thereof, and thus the retraction of the line toward a position separated from the at least one operational position.

Provided are a filter cloth recovery device and a copper rod continuous casting and rolling manufacturing system using the same. This device includes a cleaning water tank, a winding mechanism and a cleaning mechanism provided on the cleaning water tank. The winding mechanism includes: a winding shaft provided on the cleaning water tank for winding a filter cloth after being cleaned; a first guiding roller for guiding a filter cloth to be cleaned into a cloth-transmitting path within the cleaning water tank; and a second guiding roller between the first guiding roller and the winding shaft along the cloth-transmitting path for providing a tension force to the filter cloth. One end of the winding shaft is connected with a driving mechanism. The cleaning mechanism is provided with multiple liquid spraying openings for spraying a cleaning fluid to the filter cloth located in the cloth-transmitting path during winding.

A hybrid rolling mill includes at least one work stand and a lubrication system. The at least one work stand includes an upper work roll and a lower work roll. The lubrication system includes a first lubricant applicator and a second lubricant applicator. The first lubricant applicator is configured to supply a first lubricant at an entry side of the work stand in a first rolling mode. The second lubricant applicator is configured to supply a second lubricant at the entry side of the work stand in a second rolling mode.

The invention relates to an apparatus (1) for the applying of and removal by suction of operating fluids onto rolling stock (2) and off rolling stock (2) in the inlet (4) of cold rolling systems (6) and comprises at least one spray device (7) arranged above or below a rolling stock transport line (8), wherein at least one operating fluid can be placed by the spray device (7) onto a surface of the rolling stock (2) or onto a surface of a working roll (9) which makes contact with the rolling stock (2), and to at least one suction removal device (10) which can be arranged above or below the rolling stock transport line (8) and on the same side of the rolling stock transport line (8) as the spray device (7), wherein the suction removal device (10) acts in the vicinity of the surface of the rolling stock (2) or of the working roll (9). The spray device (7) and the suction removal device (10) are attached onto a common component frame (12) and therefore form a compact unit (14.1; 14.2).

A cold rolling mill rolling condition calculation method includes: an estimation step of estimating a rolling constraint condition with respect to a target steady rolling condition of a roll target material, by inputting second multi-dimensional data to a prediction model, the prediction model having been trained with explanatory variable and response variable, the explanatory variable being first multi-dimensional data generated based on non-steady rolling performance data, among past rolling performance in rolling a roll material by a cold rolling mill, and the response variable being steady rolling performance data and rolling constraint condition data during steady rolling, and the second multi-dimensional data having been generated based on non-steady rolling performance data of the roll target material; and a change step of changing the target steady rolling condition so that the estimated rolling constraint condition satisfies a predetermined condition.

The invention relates to a sheet steel skin-pass rolled with a deterministic surface structure, and to a method for producing it.

A spray device lubricates and cools a strip and/or an air gap of a roller stand having multiple rollers. The spray device has a fixed spray table with an elongated shape and configured to be rigidly connected to a plurality of mounting plates in a row of bearing rollers of the roller stand. The fixed spray table includes a network for dispensing a fluid for lubricating and cooling via a plurality of nozzles, a connector for connecting the fluid-dispensing network to a network for supplying the fluid, and an attachment device for rigidly connecting the table to the mounting plates.
