Abstract: An installation for producing hot-rolled steel strip, including a continuous casting machine, a shear, a soaking furnace, a descaler, possibly a roughing train, a finishing train including a multi-stand rolling mill or Steckel mill, a roller table with a cooling zone, and a coiling reel for the hot strip. The casting line and the pass line are arranged parallel or approximately parallel to each other so that the casting direction and the rolling direction are oriented opposite each other and are connected with each other by a reheating furnace. The reheating furnace is a rocker-bar hearth furnace or a walking-beam furnace. The distance between the casting line and the pass line is designed so that a sufficient residence and buffering time for the thin slabs in the reheating furnace is guaranteed. The reheating furnace is designed to hold from three to twelve slabs.

Abstract: A method for removing loose scale and other foreign matter from the top and/or bottom face of a cast product with the aid of flowable media which are sprayed onto the cast product by a cleaning device having at least one spraying apparatus that is disposed above the cast product and at least one spraying apparatus that is arranged below the cast product. According to the method, the amount of media and/or the effective width and/or the pressure of the media is/are controlled separately and independently of time for each spraying apparatus.

Abstract: The invention relates to a continuous casting mold, in particular a thin slab mold in which the flow of a liquid metal in the mold is influenced by a magnetic field generated by permanent magnets, wherein the permanent magnets have, over the width and/or height thereof, different magnetic strengths or are spaced from each other by different distances for a different field strength, so that to provide for variation of the magnetic field strength, the permanent magnets are differently adjusted in groups for changing a field strength distribution.

Abstract: The invention concerns a method for producing metal strip (1) in an installation (2), in which a metal strand, especially a thin slab, is brought to a desired temperature and/or is maintained at a desired temperature in a furnace (3, 3a, 3b) and is subjected to a rolling process in a rolling train (4) downstream of the furnace (3, 3a, 3b) in the direction of conveyance (R) of the metal strand (1). In accordance with the invention, to prevent the formation of scale deposits in the downstream region of the furnace, provision is made for the metal strand (1) to be subjected to at least one descaling operation during its residence time in the region (5) of the furnace (3, 3a, 3b). In addition, the invention concerns an installation for producing metal strip.

Abstract: The invention relates to a device for the production of hot-rolled steel strip comprising at least one continuous casting machine, at least one pair of scissors, at least one calibration oven, a de-scaler, optionally, a roughing train, a finishing train (multi-stand rolling mill or Steckel mill(s)), a roller path comprising a cooling area and at least one pickup reel for the thermal strip. A compact structure is achieved by virtue of the fact that the casting line and the rolling line are arranged parallel or approximately parallel to each other such that the direction of casting and direction of rolling are oriented essentially in an opposite direction to each other.

Abstract: A method for producing thin slabs whereby the cross-section thereof is reduced during solidification in a continuous casting device wherein the strand guide adjacent to the mold includes wedge-shaped adjustable roller-strand sections for regulating the thickness of the strand or the thin slabs. The thickness of the strand is reduced only on one point of the strand guide below the first segment downstream from the mold in an area of the strand containing a liquid core by regulating the strand guide rollers with a soft transition. The segment following the segment situated directly after the mold comprises a pivoting point on the input side and an adjusting means arranged on the output side.

Abstract: The invention relates to an electromagnetic braking device for molten steel that flows into a continuous casting mould (1). Said device comprises at least one solenoid (2) with a ferromagnetic core (5) that is allocated to the broad sides (3, 4) of the mould. To reduce the oscillating mass and at the same time increase the strength of the magnetic field, the core (5) consists of a primary part (6) that houses the solenoid (2) and can be displaced at a distance from the broad side walls (3, 4) and attachments (8, 8?) that are fixed in water tanks (7, 7?) of the mould (1). When combined in their operating position, the core parts (6, 8) produce U-shaped yokes (9, 9?) for generating a closed magnetic flux (10) and when moved apart, cause the magnetic flux (10) to be interrupted.

Abstract: The invention relates to a device for the continuous casting of metals, especially steel, for use in a solidified-bending method. Said device comprises, downstream of the continuous casting mold, a straight strand guide (1) and a bending device (3) that releases the cast strand path (2a) so that the cold strand (5) can be introduced. The object of the invention is to utilize the height of the device that has so far not been used for supporting the strand or to reduce the height of the entire installation. To this end, the bending device (3) comprises a folding segment (9) that is pivoted on the fixed side (1a) and that is provided with a row of rollers (10) that limit the bending path (3c) in the operational position. The bending device further comprises on the loose side (1b) a loose element (11) that can be swiveled into the operational position (3b) or that can be swiveled out from this position.

Abstract: A tundish carriage for a double-strand continuous caster has a carriage frame displaceable on rails straddling a pair of parallel-wall or funnel-shaped continuous casting billet molds. The frame is of trapezoidal configuration with one relatively long beam and one relatively short beam connected by transverse beams at vertices provided with bolsters riding on the rails and with units for raising and lowering the trough for receiving the molten metal. The casting tubes extend downwardly from the trough and can be individually aligned with the respective molds without affecting the position of the other casting tube, utilizing an adjusting device at each bolster connecting a transverse beam with the longer of the longitudinal beams.
