摘要： A method for setting different cooling rates of metal strips or metal plates (rolling material) over the strip width of a cooling stretch in a hot-strip mill or heavy-plate mill is presented. According to the method, for the calculation of the cooling rate, the initial enthalpy distribution over the material width of the rolling material before the cooling is determined. Proceeding therefrom, a target enthalpy distribution is determined in the width direction and length direction of the rolling material while taking into account a calculation of the flatness and the mechanical properties by means of a microstructure model. Subsequently, the coolant amount and the coolant curve of the cooling stretch are set.

摘要： Described herein is a method for rolling metal sheets of variable thickness. The method makes it possible to impress, during rolling, any distribution of areas of increased thickness within a figure corresponding to the plane development of a motor-vehicle component prior to the pressing operation. Impression of the desired distribution of areas of increased thickness envisages simultaneous impression, during rolling, of a further distribution of areas of increased thickness, or compensation areas.

摘要： Methods and apparatus to monitor conditioning machines are disclosed herein. An example system includes a plurality of work rolls to process a continuous strip material positioned between an entry and an exit of an apparatus. A sensor determines a measured distance between an upper surface of the strip material and a reference location, where the sensor is downstream from the exit of the apparatus. A controller determines a difference value between the measured distance and a predetermined distance to detect material curvature in the strip material.

摘要： A steel strip is fed and compressed between a driving roller and a compression roller to generate a stress greater than a yield stress in the steel strip and to elongate one periphery portion of the steel strip, which is on one side, more than the other periphery portion of the steel strip, which is on the other side, in a sending direction. The compression roller includes a first contact portion and a second contact portion. The second contact portion extends from an end of the first contact portion in the axial direction of the compression roller. The end of the first contact portion has an outer diameter less than an outer diameter of the second contact portion.

摘要： A method for producing a metallic strip by continuous casting-rolling, wherein a slab is cast in a casting machine and then sent to a finishing mill located downstream, relative to the transport direction of the strip. In the event that the transport of the slab or strip comes to a complete or substantially complete standstill, the following steps are carried out: (a) cutting through the strip at a first point; (b) cutting through the strip at a second point that is 0.1-5.0 m upstream from the first point; (c) removing the cut-out piece of strip to create a gap in the strip; (d) conveying new strip material into the area of the gap from the area located upstream of the first point; and (e) cutting off pieces of the new strip material conveyed from upstream according to step (d) and removing the pieces from the transport line.
