The invention relates to a method for producing a metal strip (1) by continuous casting. According to said method, a slab (3), preferably a thin slab, is initially cast in a casting machine (2), said slab being deviated from a vertical direction (V) into a horizontal direction (H), and in the direction of transport (F) of the slab (3) arranged behind the casting machine (2), the slab (3) is subjected to a milling operation in the milling machine (4), in which at least one surface of the slab (3), preferably two surfaces which are opposite to each other, are milled. In order to obtain a high economic viability and improved machining parameters when the strips are rolled, the slab (3) is milled as a first mechanical machining step after the slab (3) is deviated in the horizontal direction (H). The slab (3) is cast with a thickness (d) of at least 50 mm and the slab (3) is cast with a mass flow, which is the product of the casting speed and the slab thickness (v×d), of at least 350 m/min×mm. The invention also relates to a device for producing a metal strip by continuous casting.

A method for drying a strip (3) or sheet metal that runs through a rolling mill is characterized in that the strip (3) or the sheet metal is cooled to a lower temperature in a cooling section by means of a coolant, in particular a cooling liquid, down-stream of a hot strip mill (1) or, in case of sheet metal, after passing through at least one roll stand (2), and in that the coolant, in particular the cooling liquid, and subsequently the moisture remaining on the strip (3) or the sheet metal is removed from the strip (3) or sheet metal by means of a drying apparatus (10).

The invention is directed to a cylindrical milling cutter whose cylindrical body is provided with grooves which extend along its length at a distance from one another and at an angle to the longitudinal axis, and indexable cutting inserts, particularly coated carbide cutting inserts, are arranged in these grooves. For substantially preventing axial forces acting on the milling cutter or on the material to be machined, it is proposed either that the grooves and therefore the knife edges of the indexable cutting inserts are portionally oriented at different angles, these angles being selected such that the axial forces occurring in one portion during the machining process are neutralized or reduced in a defined manner by the axial forces occurring in the adjacent portion, or that the indexable cutting inserts are alternately arranged or oriented in the grooves in such a way that the axial force caused by one indexable cutting insert during the machining process is neutralized by the axial force caused by the adjacent indexable cutting insert.

The invention relates to a device for producing a metal strip (1) by continuous casting, using a casting machine (2) in which a slab (3) is cast. At least one milling machine (4) is arranged in the direction of transport (F) of the slab (3) behind the casting machine (2). At least one surface of the slab (3), preferably two surfaces which are opposite to each other, can be milled in said milling machine. According to the invention, in order to obtain high quality surface machining by milling, in particular in relatively rigid slabs, a shaving conveying device (6) is arranged in the region of at least one milling cutter (5) of the milling machine (4) enabling the milled shavings (7) to be removed from the region of the milling cutter (5) in the direction (Q) perpendicular to the direction of transport (F) of the slab (3).

The invention relates to a compact, flexible CSP installation (1,101,201,301,401) for endless, semi-endless and batch operation with a casting machine, a roughing stand group (7,111,211) and a finishing stand group (12,118,218), wherein for the batch operation or the semi-endless operation, a coil store (8,113,213,501) is integrated into the roll table, which stores the pre-strip or slab coming from the roughing stand, with the coil store being deactivated in the case of endless operation. The coil store (8,113,213,501) is designed for an increased holding quantity of pre-strips or slabs such that two, three or more pre-strips or slabs can be wound to jumbo coils on a coil.

The rolling operation is divided into at least two partial-rolling operations in at least one first rolling train (5) and one second rolling train (6). The milling operation in the milling machine (4) is carried out directly prior to the first rolling operation or between both rolling operations. The invention also relates to a device for producing a metal strip (1) by continuous casting.

The invention pertains to a device for influencing the temperature distribution over the width of a slab or a strip, particularly in hot strip rolling mill, wherein at least one cooling device is provided that features nozzles for applying a cooling medium, wherein the nozzles are arranged and/or actuated in such a way that the cooling medium is applied, in particular, at positions at which an elevated temperature is determined. The invention furthermore pertains to a device for influencing the state of the surface evenness of the strip by means of strip cooling, wherein the cooling device is controlled in dependence on the state of surface evenness of the strip in such a way that the surface unevenness is reduced or eliminated. In addition, this invention makes it possible to purposefully influence the strip contour, wherein the strip or the slab is cooled widthwise in such a way that the strip contour approximates a desired target contour more closely.
