  • Method for controlling and/or regulating the cooling stretch of a hot strip rolling mill for rolling metal strip, and corresponding device
    Patent number: 6866729
    Abstract: A method and device for the automation of a cooling section in a hot strip rolling mill, wherein an individual course of cooling over time for each strip point of the metal strip is specified and whereby the cooling specifications can be determined from the desired properties of the steel, independent of variable process value.

  • Method for controlling and/or regulating the cooling stretch of a hot strip rolling mill for rolling metal strip, and corresponding device
    Publication number: 20030089431
    Abstract: The joint properties of a metal strip being rolled in a hot strip rolling mill, especially a steel strip, are adjusted in the cooling stretch of said mill by cooling. According to the invention, a time-related cooling course is predetermined for each strip point of the metal strip. An individual cooling curve is established as a function of time for each strip point, the established time curve is constantly compared with the model time-related cooling curve for each strip point and process control signals for controlling and/or regulating the cooling stretch are derived from this comparison. The corresponding device is provided with a calculating device and a process control device.
