Abstract: A device and a method for producing a continuous strip-shaped composite material. For this purpose, a base material, which is produced using at least one casting machine as a continuous strand, in particular made of steel, and providing at least one cladding material, which is unwound in the form of at least one metal strip by a coil unwinding unit are provided. Subsequently, a slab which has formed by solidification from the strand produced by the casting machine and the metal strip unwound by the coil unwinding unit, in the hot state are brought together, wherein the materials, which are moved in the direction toward one another, formed from the slab and the unwound metal strip are hot rolled, so that a single continuous strip-shaped composite material is thus produced by roll cladding. The base material is continuously cast in the vertical direction in the casting direction.

Abstract: The invention relates to an apparatus and to a method for separating condensable materials from an exhaust air stream. Known apparatuses of this type typically comprise a flow duct for the correspondingly contaminated exhaust air, wherein a first separator (114) and a second separator are connected in series in the flow duct (110). A fan is typically connected downstream of the two separators and operates as a suction fan in order to draw the exhaust air through said separators and to discharge the exhaust air to the environment after it has passed through both separators. In a rolling mill, order to observe predefined limit values for the proportion of condensable materials in exhaust air streams before such streams are discharged into the ambient air, the present invention provides for the exhaust air to be separated at the rolling mill itself, and, downstream, for the fan to be placed not at the outlet of the separators but upstream of the first separator.

Abstract: To increase the load-carrying capacity or rolling capacity of a roll assembly in a rolling mill, throttle elements are used, which shut off the lateral flow of the lubricating film in a partial region between the roll neck and the bearing surface of the roll neck bearing assembly, thereby bringing about an increase in pressure in the lubricating film. At least one throttle element is embodied as an annular segment, forming an angular shut-off region for the lubricant in the annular gap. The invention makes it possible for existing installations to be easily retrofitted, without the need for structural modifications. In the case of new installations, the same load-carrying capacity as before can be provided while the dimensions of the installation space are reduced. The load-carrying capacity of the bearing assembly can be flexibly adjusted based on the dimensions of the shut-off region for the flow of lubricant.

Abstract: A method for producing a metallic strip by continuous casting-rolling, wherein a slab is cast in a casting machine and then sent to a finishing mill located downstream, relative to the transport direction of the strip. In the event that the transport of the slab or strip comes to a complete or substantially complete standstill, the following steps are carried out: (a) cutting through the strip at a first point; (b) cutting through the strip at a second point that is 0.1-5.0 m upstream from the first point; (c) removing the cut-out piece of strip to create a gap in the strip; (d) conveying new strip material into the area of the gap from the area located upstream of the first point; and (e) cutting off pieces of the new strip material conveyed from upstream according to step (d) and removing the pieces from the transport line.

Abstract: A strip deflector has a base body formed with a tip, a compressed-air chamber, and a nozzle for emitting compressed air. A compressed-air source in flow communication with the compressed-air chamber feeds compressed air to the compressed-air chamber and the nozzle. This nozzle has a first nozzle subpassage in flow communication with the compressed-air chamber and a second nozzle subpassage downstream of the first nozzle subpassage in a flow direction. The first nozzle subpassage is formed by a flank closer to the tip of the base body and an opposite flank remote from the tip of the base body, and, at a transition from the first nozzle subpassage to the second nozzle subpassage, the flank closer to the tip of the base body is bent away toward the tip of the base body so as to form a first separation edge.
