摘要： A method for determining mechanical properties of a first rolled material by a hybrid model that includes production datasets relating to further rolled materials, a physical production model and a statistical data model. The production dataset relating to the first rolled material is used to determine a first mechanical dataset, a further production dataset and a metallurgical dataset and also a second mechanical dataset. An averaged normalized distance value for production datasets relating to the further rolled materials is determined that is used to ascertain the mechanical properties of the rolled material as a weighted average from the first and second mechanical datasets. When creating the hybrid model, the physical production model is used to determine further production datasets relating to the further rolled goods for training the statistical data model.

摘要： A method for setting a roll gap of sinusoidal corrugated rolling for a metal composite plate includes steps of: determining entrance thicknesses, exit thicknesses, a width, and a rolling temperature of a difficult-to-deform metal slab and an easy-to-deform metal slab; detecting a roll speed and an entrance speed of a metal composite slab, obtaining a roll radius and friction factors; determining parameters of a sinusoidal corrugating roll and a quantity of complete sinusoidal corrugations on the sinusoidal corrugating roll; then calculating a time required for a complete corrugated rolling; calculating a rolling force at any time during the sinusoidal corrugated rolling of the metal composite plate; and calculating the roll gap S of the corrugated rolling at any time according to the rolling force F, and configuring a rolling mill to have the roll gap S according to an actual rolling schedule before normal production.

摘要： A method and a device for guiding and centering a metallic rolling stock in a rolling mill having at least one assembly that is arranged in a rolling line and at least one rolling mill stand for shaping the rolling stock are disclosed. The method includes the use of lateral guide means, which exert a lateral force onto the moving rolling stock at different locations of the rolling line, wherein the method further includes the process of centering the inflow of the rolling stock ahead of a first assembly and/or ahead of a first rolling mill stand of the rolling mill using first lateral guide means and the process of aligning rolling stock downstream transversely to the rolling line using second lateral guide means, wherein the process of centering the inflow includes a funnel-shaped, flat guiding of the rolling stock and a point-shaped guiding of the rolling stock.

摘要： The invention relates to a method for modelling the behaviour of a circular rolling mill (1) intended for rolling a cylindrical component on the basis of a setpoint, the circular rolling mill comprising at least one tapered roller (3) configured to effect a translational movement in a first direction (Y), and a mandrel (2), configured to effect a translational movement in a second direction (X), the setpoint comprising a setpoint for the rate of increase of an outside diameter of said cylindrical component as a function of said external diameter, and a setpoint for the height of the cylindrical component in the first direction as a function of a thickness of the cylindrical component in the second direction.

摘要： A chattering detection method for a cold rolling mill, the method including: measuring a vibration of a cold rolling mill; calculating a time waveform of vibration intensity by performing frequency analysis on a time waveform of the measured vibration of the cold rolling mill for a predetermined period equal to or shorter than a time in which a periodic vibration continues without converging; and detecting a chattering sign vibration of the cold rolling mill based on a number of points having vibration intensity values that exceed a predetermined threshold, the points being included in the calculated time waveform of the vibration intensity.

摘要： Hot rolling stock (1) made of metal which is rolled in at least one roll stand (2) and then cooled in a cooling section (5) arranged downstream of the at least one roll stand (2). Sound generated by means of a sound generator arrangement (8) is coupled into the rolling stock (1) by a coupling device (1) so that a standing sound wave is formed at least in the region of the rolling stock (1) which is located in the vicinity of the coupling device (10).
