Abstract: A plant and process for the continuous production of hot-rolled steel strips with a minimum thickness of 0.3 mm is disclosed which includes a continuous casting device of thin or medium slabs with a thickness between 40 and 150 mm and a maximum width of at least 2100 mm followed by a roughing mill, a first induction furnace, a water descaler, a second induction furnace, a finishing mill, a cooling station, a cutting station and a winding station. A system for feeding a protective atmosphere containing ≤3% vol. oxygen is provided from the inlet of the second induction furnace to at least the third stand of the finishing mill. Between the continuous casting device and the roughing mill, an initial thermal conditioning and descaling section is provided having in sequence an induction edge heater, an induction heater for the rest of the slab surface and a water descaler.

Abstract: A method for revamping a starting rolling plant, for producing a final strip starting from a slab having a determinate starting thickness, including: at least one heating furnace configured to heat at least the slab to a determinate starting temperature; at least one reversible roughing stand configured to subject the slab to one or more rolling passes in order to obtain an intermediate rolled product; and a rolling train disposed operatively in line with the roughing stand, including at least one pre-finishing stand and a plurality of finishing stands and configured to reduce the thickness of the intermediate rolled product, until the final strip having a determinate final thickness is obtained.

Abstract: Systems and methods for reducing the thickness of a strip of an aluminum-based material are disclosed. The aluminum-based material is pre-heated before running the material through a warm rolling process. The systems include devices for pre-heating, which can include a heated payoff station or a dedicated pre-heating station that applies heated rolls or acts as a heated tunnel.

Abstract: The invention relates to a finishing train for finish rolling hot strip. It is the object of the invention to modify an existing finishing train in such a way that the surface quality of the hot strip produced is improved without, however, significantly increasing the use of energy during production. This is intended to enable the thin hot strip produced to be used even for applications with high demands on surface quality. This object is achieved by a cleaning nozzle which cleans the upper side of the exit table, thus ensuring that scale and/or rolling dust are/is removed from the exit table.

Abstract: The present invention provides a dynamic contact heat transfer simulation device for rolling heavy-load deformation zone. The device includes a control system, a data acquisition system, a pressure-adjustable fixed cold end, a rotating chuck, a temperature-adjustable heat-conducting rod and an speed-adjustable rotation hot end; the device utilizes the rotating chuck and the speed-adjustable rotating hot end to adjust the rotation speed in real time according to the actual rolling conditions, simulate the working conditions of the actual rolling heavy-load deformation zone, and accurately obtain the dynamic heat transfer coefficient of the rotating contact interface under variable load pressure conditions.

Abstract: A forge and method of forging is provided. The forge converts an asymmetric railroad rail to a symmetric railroad rail through a combination of vertical and horizontal forging operations. The rail is linearly translated to heating and forging stations on a roller table. The asymmetric to symmetric conversion can be completed without the need for reorienting the rail except along a single translational axis.

Abstract: A first steel strip and a second steel strip (7) are rolled in succession in at least one roll stand (1) of a cold rolling mill. A rolling pause, in which no steel strip is rolled, is provided between the rolling of the first and the second steel strip (7). The first steel strip s fed over a first path starting from a first pay-off reel (2), and the second steel strip (7) is fed over a second path starting from the first pay-off reel (2), or from a second pay-off reel different from the first pay-off reel (2). The first steel strip is not heated as it is fed to the rolling mill (1), whereas, by contrast, the second steel strip (7) is heated. The second path is longer than the first path.
