  • Patent number: 8596335
    Abstract: A method for continuous casting from molten metal, where metal flows vertically downward from a mold and the metal strip is then guided vertically downward along a vertical strand guide, cooling as it moves. The strip is then deflected from the vertical direction to the horizontal direction. In the terminal area of the deflection of the strip into the horizontal direction or after the deflection into the horizontal direction, a mechanical deformation of the strip is carried out. The strip is cooled at a heat-transfer coefficient of 3,000 to 10,000 W/(m2 K) in a first section downstream of the mold and upstream of the mechanical deformation of the strip. In a second section, downstream of the cooling, the surface of the strip is heated to a temperature above Ac3 or Ar3 by heat equalization in the strip, after which the mechanical deformation is carried out in a third section.

  • Patent number: 8205662
    Abstract: The invention relates to a method for the continuous casting of a metal strand (1), in which the cast strand (1) leaves a die (2) vertically or arcuately downwards and is subsequently guided in a strand guide (3), wherein the strand guide (3) has a number of pairs of rollers (4), which define between them an adjustable roller nip (5), and wherein, at the start of casting, to close the die (2) in the downward direction, a piece of strand (6) is introduced into the die (2) and is followed by the cast strand (1). In order to improve the adjustment of the roller nip, the invention provides that the piece of strand (6), which is produced with a defined or calibrated thickness (d), is inserted between the respective pairs of rollers to calibrate and/or measure the roller nip (5).

  • Patent number: 8162030
    Abstract: The invention relates to a mould for casting metal, having a plurality of temperature measuring devices (300) that are arranged in a wall (100) of the mould in order to detect the temperature distribution at that location. In order to make it easier to install the plurality of temperature measuring devices in the wall and in order to increase the reliability of the measurement results from said devices, it is proposed according to the invention to arrange the temperature measuring devices (300) such that they are positioned fixedly with respect to one another in a module (400), such that the temperature measuring devices together with the module form a structural unit which can be preassembled before the mould is installed. The structural unit is then fastened in or to the wall of the mould as the mould is being assembled.

  • Publication number: 20110213486
    Abstract: A method for casting a cast strand (4) in a continuous casting installation equipped with a process computer and having at least one casting machine, the process computer comprising a first software (2), which computes in real time and regulates the casting process, is characterized in that a second additional fast-computing software (1) in the process computer controls the casting process during the initial phase of a newly starting casting process or when there is a change in parameters of the cast strand to be cast during the ongoing process, in that the second software (1) processes currently gained data from the ongoing casting process and/or processes stored data from a database (8) and generates correction factors, with the help of which the second software (1) generates corrected target data for the casting process, until the time when the casting process is represented completely using the data calculated in real time, and the first software (2) regulates the casting process using only these data.

  • Publication number: 20110167905
    Abstract: The invention provides a method for the cast level measurement in a mold by means of sensors for fiber optic temperature detection, which are disposed in the mold copper plate at the height of the casting level. The invention further comprises respective sensors. Fiber optic cables are disposed in said sensors, which allow simple, reliable and highly locally resolved temperature monitoring at the height of the casting level by means of a suitable temperature analysis system. By means of the temperatures determined by the sensors, a conclusion can be made as to the exact height of the casting level. Furthermore, the shape of the casting level shaft may be determined by means of which further parameters of the casting process become accessible.

  • Patent number: 7854883
    Abstract: A system for cooling a hot rail of rail steel to a fine perlitic or ferritic or perlitic/ferritic structure has a plurality of separate cooling modules with independently adjustable cooling parameters. The rail is guided downstream through the modules of the cooling stretch and through intermediate zones between the modules so as to cool the surface of the rail in each of the modules and to subject the rail to destressing or stress relief between the modules. Sensors in each of the intermediate zones detect the actual surface temperature of the rail in the respective zones, and a controller connected to the modules and to the sensors varies the cooling parameters of the cooling modules in dependence on the detected temperatures in the respective upstream zones to ensure a defined temperature in the rail that lies above a critical temperature at which bainitic structure components are formed.

  • Patent number: 7770838
    Abstract: The invention relates to a method of releasing a reel awe, which is hydraulically restrained by a self-locking effect by means of inwardly located wedge surfaces of expansion elements. Removal of a coil from a reel awe is achieved, without problems, by lifting off the self-locking effect of the expansion elements at least partially or completely by applying longitudinal vibrations acting in an axial direction. The invention also relates to a correspondingly formed device.
