摘要： A method for the production of a hot-rolled steel strip from a steel melt in a continuous manufacturing process, with an uninterrupted strip runthrough, comprising continuously casting a steel strand in a continuous casting mold of a continuous casting plant, roll-forming the cast steel strand in a first group of roll stands into a pre-rolled hot strip, further roll-forming the pre-rolled hot strip in a second group of roll stands into a hot-rolled steel strip, setting the pre-rolled hot strip to a rolling temperature between the first group of roll stands and the second group of roll stands in a temperature setting device, and winding of the hot-rolled steel strip into bundles or the division of the hot-rolled steel strip into sheets. In order to increase flexibility in the production of different steel qualities and to keep investment costs and operating costs low, descaling the pre-rolled hot strip immediately before its entry into the temperature setting device, holding the pre-rolled hot strip in a protective gas atmosphere in the temperature setting device, and after the pre-rolled hot strip runs through the temperature setting device, roll-forming the strip immediately thereafter in the second group of roll stands. Further, a combined casting and rolling plant for carrying out the method is disclosed.

摘要： A process for continuously casting a thin metal strip controls has jets directed at casting rollers using sensor feedback. Sensor feedback can be taken directly from the rollers, or can be determined indirectly by sensing a condition of the thin metal strip. Surface conditions are controlled over a longitudinal extent of the rollers through locally controlled gas jets. The feedback control of the roller surfaces provides a more uniform casting surface and a more consistent output from the casting surface.

摘要： A method is disclosed for continuously or semi-continuously producing hot steel strip which, starting from a slab guided through a slab-guiding device, is rolled in, for example, an at least four-stand roughing train to form an intermediate strip and, in a further sequence in a finish rolling train, into a final strip. The thickness of a slab cast in a die is reduced in the liquid core reduction process by means of the adjoining slab-guiding device to between 85 and 120 mm, a slab support length measured between the meniscus, i.e., the bath level, of the die and an end of the slab-guiding device facing the roughing train being at least 18.5 m, a casting speed ranging from 3.8 to 7 m/min, and slabs of different thicknesses being cast as a function of given casting speeds. Using the disclosed casting parameters, high-quality finishing may be provided with high production capacities.

摘要： The invention relates to a method for producing a cast steel strip of preferably hot crack-sensitive or hot-brittle steel quality by means of a strip casting plant and to a strip casting plant for carrying out this method. In this case, steel melt is conducted into a melt space formed by two casting rolls and two sideplates, slab shells are formed in the melt space on cooled surface areas of the casting rolls and are brought together in the strip forming cross section between the casting rolls to form an at least partly solidified steel strip, the cast steel strip is then guided along the surface area of one of the two casting rolls from a vertical casting direction into an essentially horizontal transport direction, and the cast steel strip is supplied essentially horizontally on a transport device to a strip winding device and is wound there into a coil. In order in this case to minimize susceptibility to crack formation, the cast steel strip, during its transport movement along the surface area of one of the two casting rolls, is guided in a transport channel without the application of deformation forces influencing the strip thickness and is subjected in this region to strip cooling of less than 200 K/s.

摘要： To start up a casting operation in a two-roll casting device without the use of a start-up strand, the method comprises setting an operating casting thickness and rotating the casting rolls at a casting-roll circumferential velocity which corresponds to a starting casting velocity, which is lower than a steady-state operating casting velocity, feeding metal melt into a melt space formed by the rotating casting rolls and the side plates to form a cast metal strip with a substantially constant, predetermined cross-sectional format while at the same time increasing the casting velocity to a strip-forming casting velocity, then increasing the casting velocity to a strip-separating casting velocity, which is significantly higher than a casting velocity which is sufficient for the prevailing full solidification conditions, and separating off the metal strip which has been cast thus far, setting a steady-state operating casting velocity, diverting the subsequent cast metal strip to a strip-conveying device and commencing steady-state casting operation.

摘要： A casting roll for the continuous casting of thin metal strips, in particular steel strips in a double-roll or roll-in installation. The roll comprises a roll core with an external casing and an annular roll jacket with an internal casing. The jacket surrounds the core and is being shrunk onto the latter. To prevent migratory motion of the roll jacket in relation to the roll core, the surface of at least one of the opposing casings that form a shrinkage connection has protuberances and indentations, which are oriented at least partially in the direction of the casting roll axis and extend radially for at least 2 μm.
