Abstract: A method for producing a metal product, wherein in a strand casting system, liquid metal is output as a slab from a mold vertically downward in a conveying direction, is guided along a strand guide, and is deflected into the horizontal, wherein the slab is heated in a furnace or inductively downstream of the stand casting system.

Abstract: A method for continuous casting from molten metal, where metal flows vertically downward from a mold and the metal strip is then guided vertically downward along a vertical strand guide, cooling as it moves. The strip is then deflected from the vertical direction to the horizontal direction. In the terminal area of the deflection of the strip into the horizontal direction or after the deflection into the horizontal direction, a mechanical deformation of the strip is carried out. The strip is cooled at a heat-transfer coefficient of 3,000 to 10,000 W/(m2 K) in a first section downstream of the mold and upstream of the mechanical deformation of the strip. In a second section, downstream of the cooling, the surface of the strip is heated to a temperature above Ac3 or Ar3 by heat equalization in the strip, after which the mechanical deformation is carried out in a third section.

Abstract: A method and a device for improving the outer surface quality by an in-line outer surface treatment of slabs, which are produced in a continuous process from strand casting to hot rolling, with a heating furnace arranged between a CSP-casting machine and a hot rolling train. A defined surface of the slab with a layer thickness per slab side of up to 4 mm is oxidized in a targeted manner by an oxidation device. An oxidation treatment of the slab surface is combined with the following processing in-line method steps: prior to the oxidation treatment the outer surface of the slab is freed of naturally occurring scale by a scale washer, after the oxidation treatment a created oxidation layer as well as the newly formed scale is cooled, mechanically broken up in a roll pair and removed from the surface of the slab by a scale washer.

Abstract: The aim of the invention is to improve the surface quality of slabs (5) having a thickness of up to 400 mm, that are produced in a continuous process from continuous casting to hot-rolling, for example according to the CSP method, by means of an in-line surface treatment. To this end, a defined surface layer of the slab (5) with a layer thickness per slab side of up to 4 mm is oxidised in a targeted manner by an oxidising flame or an oxidising gas mixture applied to the upper and lower sides of the slab (5) by means of an oxidation device containing nozzles or a similar device, said layer being removed later on during the process. The oxidation product on the slab surface can be solid or liquid.

Abstract: Disclosed are a method and a casting/rolling plant for producing hot-rolled metallic, particularly steel, strips (7) having great surface quality from slabs or flat thin bars (2, 2a) that are cast in a continuous casting process, descaling being performed based on a rotary descaling process. In order to take into account parameters which are not considered in prior art in addition to rotary descaling, the hydraulically oscillated permanent mold (9) travels along several different oscillation curves (16, 17, 18) while the oscillation marks are deep-cleaned by adjusting the oscillation pattern that is determined to be optimal for each casting material.

Abstract: The invention relates to a process for the continuous casting of a slab (1), in particular of steel, wherein the cast slab (1) is conveyed through a furnace (2) and the slab (1) is subjected to a descaling operation. To increase the quality of the slab by reducing scale, the invention provides for the slab surface to undergo reduction in at least one section (3) of the furnace (2) as a result of an atmosphere consisting of an inert gas and hydrogen (H2) or of pure hydrogen being maintained in said section (3) of the furnace (2). The invention further relates to an apparatus for the continuous casting of a slab.
