摘要： An apparatus for producing hot-rolled products in a combined casting-rolling installation designed to bridge a planned or unplanned interruption in production downstream of the cutting-up and delivering device. The installation cuts off a strand portion of the continuously produced preliminary material using first shears; raises the tail part of the strand portion from the roller table using a raising device; breaks up the preliminary material passing the first shears into pieces of scrap using the first shears into pieces of scrap using the first shears; delivers the pieces of scrap and removes the strand portion unit the operational readiness of the combined casting-rolling installation is restored.

摘要： in a cylinder and/or a roller and in a method for producing and/or for the maintenance of a cylinder and/or roller, a metal layer (8, 9, 10) is applied, at least in parts, to the outer surface (2) of the cylinder (1, 1″) and/or the roller (1′). The metal layer (8, 9, 10) has a ductile metallic matrix (4) having embedded hard material particles (5). Such a cylinder and/or roller can be used in a device (11) for controlling the wear and tear of a cylinder (1, 1″) and/or roller (1′), the surfaces (2′) of which are subjected to wear and tear. The method for producing the cylinder and/or roller, the cylinder and/or roller, and the device for controlling wear and tear, allow the maintenance, costs and labour of the cylinder and/or roller to be reduced.

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 two-roll casting installation with two casting rolls which rotate in opposite directions about horizontal axes and forming a casting gap for forming and discharging a thin cast metal strip. A sealed housing which has a base and surrounds a conveying path for the metal strip which leaves the casting gap and which strip is from a vertical casting direction into an approximately horizontal conveying direction. Diverter devices divert the metal strip within the housing. A displaceable scrap collection container removes scrap and scale produced from the two-roll casting installation. To minimize the penetration of external air into the housing, the base of the housing, at least in a subregion, forms a collection trough for the scrap, which is part of an emptying device, and a displaceable scrap collection container is arranged in a receiving position below the emptying device.

摘要： A process for the continuous production of a thin steel strip, in which a steel melt from a melt reservoir is introduced onto one or more, in particular two, cooled shaping wall surfaces which move synchronously with a casting strip, in particular rotate in the form of casting rolls and at least partially solidifies at the shaping wall surface to form the casting strip. The steel melt, in terms of the crucial alloying constituents, contains less than 1% by weight of Ni and less than 1% by weight of Cr and less than 0.8% by weight, in particular less than 0.4% by weight, of C and at least 0.55% by weight of Mn. In the process, recesses are arranged on the shaping wall surface in a random pattern, distributed uniformly over the shaping wall surface, and the roll separating force (RSF) at the shaping wall surface is set to a value of between 5 and 150 N/mm, in particular between 5 and 100 N/mm.
