Walter Taschner has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method of producing a plate of steel
    Patent number: 4684053
    Abstract: In a method of producing heavy plate of steel, a prematerial is hot-rolled in several passes. As the prematerial at least two slabs of the same steel quality are superposed so as to form a pack and are welded by roll-bonding and reduced in thickness.
    Type: Grant
    Filed: November 5, 1984
    Date of Patent: August 4, 1987
    Assignee: Voest-Alpine Aktiengesellschaft
    Inventors: Thorwald Fastner, Max Mayrhofer, Walter Taschner

  • Method of producing fine-grain sheet or fine-grain plate of austenitic steels
    Patent number: 4086105
    Abstract: In a method of producing fine-grain sheet or plate, in particular fine-grain plate with a thickness of more than 50 mm, of austenitic steels by hot rolling billets or slabs in a number of passes, the mean velocity of the reduction in thickness (v in mm/min) achieved in a plurality of subsequent passes in dependence upon the ferrite content (f in %) of the steels is chosen in a manner that up to a ferrite content of 3.5%, the mean velocity of the reduction in thickness is more than 150 mm/min, and at a ferrite content of more than 3.5%, it is above a value given by the relationship v = 3.8 f.sup.2 - 60 f + 315, the deformation carried out in this manner amounting to at least 30%.
