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).

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

A device for lubricating the cylinders of a roll stand, in particular for roll nip lubrication in a roll stand for strip-shaped rolling stock. A mixture of water and oil is produced by a mixing and spraying device (1). The mixture is sprayed onto at least one of the cylinders (2) of the roll stand and/or to the surface of the rolling stock (3). The mixing and spraying device (1) include an arrangement of several nozzle mixer units (4). Water is guided thereto by a first supply line (5) and oil is guided thereto by a second supply line (6).

The present disclosure relates to a lithium rolling apparatus for forming a lithium foil by rolling a lithium sheet and includes a first roll which contacts a first surface of the lithium sheet; a second roll which contacts a second surface of the lithium sheet; and a first conveyor device disposed at a rear side of the first roll and the second roll, including a belt which transports the lithium foil while controlling tension applied to the lithium foil by surface-contacting at least a part of the second surface of the lithium foil.

This manufacturing method for a slab is a method for manufacturing a slab by a continuous casting equipment including a twin-drum type continuous casting apparatus, a cooling apparatus, an in-line mill, and a coiling apparatus. The method includes calculating a friction coefficient from measured values of a rolling load and a forward slip when the slab is rolled, by use of a rolling analysis model, and controlling a lubrication condition during rolling of the slab so that the friction coefficient falls within a predetermined range, wherein, when the friction coefficient is calculated from the measured values of the rolling load and the forward slip by use of an Orowan theory and a deformation resistance model formula based on a Shida's approximate formula as the rolling analysis model, the predetermined range is 0.15 or more and 0.25 or less.
