The invention relates to a strip-casting machine () for producing a metal strip (). Said strip-casting machine comprises a pair of casting rolls () which are arranged adjacent to each other, form a casting gap and are rotatably mounted on a machine tool table (). The casting rolls () and at least the machine tool table () carrying said rolls can be displaced on rails () or the like from the casting position (G) into a waiting position (W) and vice versa. The machine tool table () together with the casting rolls () can thereby be displaced away from the casting position (G) by such a distance that a second machine tool table () that is provided with prepared casting rolls () can be displaced into the casting position (G). The machine tool table () is held in a displaceable manner and preferably together with a housing () which surrounds said table. The inventive strip-casting machine allows for quick maintenance or quick changing of the casting rolls and an increase in the casting performance thereof.

Strip-casting machine for producing a metal strip and a method for controlling same

A method for extending the casting cycle for the two-roll strip casting of a steel strip, with inline rolling thereof, the steel strip being rolled in at least two successive rolling units of a rolling mill having replaceable working rolls. The casting process is carried out independently from the roll replacement by replacing the working rolls of one rolling unit during the casting, below or above the steel strip. An installation for carrying out the method includes a lifting devices for lifting the working rolls off the steel strip so as not to damage the strip during the replacement of the rolls.

Method for extending the casting cycle for two-roll strip casting, and installation for carrying out said method

The invention relates to a casting roller (), for a double-roller continuous casting machine, in particular for the casting of a steel strip, comprising a cylinder sleeve () which may rotate about a fixed axle (). Intermediate rings () rotating with the cylinder sleeve () are arranged between the cylinder sleeve () and the axle (), which are provided with radial pressure means (), acting on the cylinder sleeve (). The above comprise a pressure chamber (), pressurized with a fluid pressure medium and acting on a pressure ring () fixed to the inner wall of the cylinder sleeve (), which may be deformed in the radial direction by inductive heating or radiated heat. The external profile of the casting roller () may be globally altered or local fine adjustments made by pressurizing the pressure chamber () with the pressure medium, or by heating the pressure ring ().

Casting roller for a double-roller continuous casting machine

The invention relates to a method of operating a strip casting machine for producing a metal strip, during which molten metal is continuously poured between two casting rolls () that form a casting gap. Lateral seals () having sealing plates () are provided for laterally delimiting the casting gap, whereby the sealing plates () are placed or pressed with a preset placement or pressing force, whose magnitude can be set, against the end surfaces of the casting rolls (). The sealing plates () are, in repeatable stop-and-go steps, placed with a preset force and time against the end surfaces of the casting rolls () and are held in the placing position for a preset time. This enables a distinct reduction in the wear of the sealing plates and of the casting roll end surfaces.

Method for operating a strip casting machine for producing a metal strip

The reliable sealing of a gap (), between a roller front face () and a side seal () on a roller-strip-casting machine is achieved by the generation of an electrical eddy field in the region of the gap (), such as to produce a local gradient field (). The eddy currents generated in the metal melt for casting prevent the ingress of the metal into the gap () or eject the metal from the gap (). The risk of escape of liquid metal is essentially eliminated and the formation of ridges on the narrow edge of the metal strip avoided.

The invention relates to a strip-casting machine for production of a metal strip, comprising two adjacent case-width casting rollers (), forming a casting gap (), with side seals () arranged on the front face thereof. The rotating casting rollers are mounted on a machine mount (). Between the above and the side seals (), the metal melt, introduced by means of at least one casting tube (), or similar, is protected by at least one gaseous medium. At least said casting rollers () are surrounded on at least the case width and front face thereof as well as the side seals by a preferably multi-component housing (). An optimal sealing of the casting rollers as well as the metal strip and the metal strip appearing from between the rollers can thus be achieved in a simple manner.

Strip-casting machine for production of a metal strip

The invention relates to a method for operating a strip casting machine (), whereby molten metal () is poured between two rotatable casting rolls (). A gaseous film (G) is formed between the respective surfaces () of the casting rolls and the strip skin (D, D, D) forming on the molten metal, the gas being introduced essentially into the inerting chamber () above the metal bath. During the casting, a controlled quantity of a gas consisting of argon, nitrogen and/or another gas is introduced into the inerting chamber () in such a way that the heat transfer from the strip skin to the casting rolls () can be influenced by the thickness of the gaseous film (G) in such a way that the surfaces (') of the casting rolls can be provided with or without cavities (). A smooth surface can thus also be obtained on the strip cast.

A refractory pouring spout and channel unit for the arrangement on the outlet of a tundish of a strip casting installation has at least one vertical, refractory pouring spout and channel part () which can be connected to the tundish; and a refractory pouring spout and channel part (') which originates from said vertical part, which extends horizontally and which is provided with one or more openings that are distributed over its length. This results in almost constant laminar flow conditions for the melt flowing between the casting rollers.
