  • Patent number: 10197533
    Abstract: A measuring device that is able to function even in rough environments, for example under great heat or in environments in which water or steam is found, as is the case in rolling mills, among other environments, has a housing, a central measuring device that passes through the housing in a straight line, and a measuring coil that is disposed in the housing and encloses the measuring opening. The device has a coil carrier that is disposed in the housing radially outside of the measuring coil and carries the measuring coil.

  • Patent number: 9808843
    Abstract: The invention relates to a roll stand (1) as a constituent part of a roll stand group (2) in a high-speed wire mill, having at least one roll pair or roll ring pair (5) and a drive shaft (7) which is connected to a motor (6), characterized in that each roll stand (1) of this roll stand group (2) is assigned a motor (6) and a drive shaft (7), and the motor (6), the drive shaft (7) and the at least one roll pair or roll ring pair (5) are arranged linearly with respect to one another.

  • Publication number: 20130152653
    Abstract: A rolling apparatus for rolling angle profiles from rolling stock has upper and lower horizontal profile rolls rotatable about respective parallel upper and lower axes and together defining an open or closed roll gap that lies in a rolling plane perpendicular to a travel direction of the rolling stock. At least one pair of nonhorizontal edging rolls laterally compress the rolling stock and define a rolling plane extending perpendicular to the travel direction of the rolling stock. The rolling plane defined by the profile rolls and the rolling plane defined by the pair of edging rolls are not coplanar with each other. This rolling stand can do angle rolling in reversing and also continuous operating mode.

  • Patent number: 8230709
    Abstract: An elongated workpiece is treated, e.g. rolled, in a production system where treatment devices move the workpiece longitudinally in a horizontal travel direction and at a generally constant travel speed along a horizontal longitudinal path and a control computer is connected to the treatment devices. Straightness of the workpiece is measured by gripping the workpiece at a pair of longitudinally spaced supports, applying tension to a longitudinally extending horizontal portion of the workpiece between the supports, and continuously moving the workpiece in the travel direction at the travel speed with a lower surface of the portion substantially unsupported. At least periodically a vertical spacing is measured between the portion and a straight longitudinal reference line extending in the direction between the supports parallel to the workpiece at the supports. The vertical-spacing measurement are fed to the computer for use controlling the devices.

  • 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: 7416622
    Abstract: In order to obtain a fine-lamellar perlite structure in the edge region of the heads of rails (1), especially hot-rolled rails for carriageways or railways, by specific thermal treatment during cooling from the rolling heat without the formation of bainite, precooling (12) occurs in order to achieve a core temperature of approximately 750-850° C., and the temperature of the more intensively cooled edge region is raised by intermediate heating (13) to at least said core temperature and finally cooled (14).
