  • Method for producing a contoured ring rolling product
    Patent number: 10464118
    Abstract: A method for producing a contoured ring rolling product for a rotating application from a ring blank, with a ring rolling machine controlled in a process-monitored manner. At least one process window, extending over the rolling time, is defined in relation to preselected process parameters for the specific product on the basis of calibrating specimens brought into their final form by the ring rolling machine. The process window(s) monitored during the process is/are determined by the process parameters of calibrating specimens which produced rolled products meeting the requirements demanded of the ring rolling product. The preselected process parameters comprise at least two of ring growing rate, axial rolling force, radial rolling force, rolling time, and ring blank temperature.

  • Method and device for producing a metallic honeycomb body
    Patent number: 6793895
    Abstract: A method for producing a metallic honeycomb body, according to which at least partly structured metal sheet is coiled, laminated or looped to form a matrix. The matrix is oscillated by an external excitation and during or after the external excitation is introduced into a casing tube.
