摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： The present invention relates to the technical field of fabricating a metal composite strip, and specifically relates to a method for differential temperature rolling of composite strips based on actions of a friction roller and a device thereof. A method for differential temperature rolling of composite strips based on actions of a friction roller comprises steps of: S1: preparing a metal strip to be bonded, and performing surface treatment on the metal strip to be bonded; S2: frictionally heating the metal strip to be bonded by several sets of friction roller heating devices; measuring a surface temperature of the friction-heated metal strip to be bonded strip by a temperature detector; according to a measured temperature, adjusting a rotation speed of the friction roller in the friction roller heating devices; and S3: transporting the heated metal strip to be bonded to a rolling mill for rolling to obtain a metal composite strip. The invention adopts the friction roller heating devices in rolling process of the metal strip to be bonded, utilizes the friction heat generation effect of the high-speed rotating friction roller and the metal strip to be bonded, and generates different heat in the dissimilar metals by adjusting the speed of the friction roller, thereby generating different temperature rise to realize different temperature rolling of the metal composite strips.
