  • Patent number: 9500410
    Abstract: An electric arc furnace has a chamber suitable for containing molten steel, a roof covering the chamber and for containing a mass of scrap steel, electrodes for melting the mass of scrap, and a supporting base. The base permits the chamber to oscillate around a horizontal axis of rotation. The roof and the chamber are counterprofiled in correspondence to the respective interface walls to create a rotary coupling with regard to the axis of rotation. The roof, during oscillation of the chamber, remains fixed with regard to the base as well as in a closed position with regard to the chamber.

  • Patent number: 9421593
    Abstract: The invention relates to a method for to-be-cooled surface of cast material, rolled material (1) or a roll. Provided for the method is a nozzle, which comprises an inlet (3) and an outlet (5) lying opposite the surface to be cooled. Also provided is a preferably single-phase volume flow (V) of a cooling fluid, which is fed to the nozzle (2) via the inlet (3) and leaves the nozzle (2) through the outlet (5). According to the invention, the nozzle outlet (5) is mounted at a variable distance (d) from the surface to be cooled, wherein the volume flow (V) of the cooling fluid fed to the inlet (3) of the nozzle (2) is set in such a way that, in accordance with the Bernoulli principle, the nozzle (2) is sucked firmly against the surface (1) to be cooled. In addition, the invention is directed to a cooling device (10) for carrying out the method according to the invention and to a rolling device comprising this cooling device (10).

  • Patent number: 9381556
    Abstract: A roller for a rolling mill with a casing, a left half pivot, and a right half pivot. The half pivots in the region surrounded by the casing are constructed as a truncated cone and form a left surface on the left half pivot and a right surface on the right half pivot. The left half pivot and the right half pivot have boreholes and corresponding grooves formed on the surfaces. The half pivots are inserted in the casing and are braced with one another by at least one tie rod. An hydraulic oil in boreholes and grooves is passed into or onto the left half pivot and the right half pivot. The hydraulic oil exerts a pressure on the casing to expand the casing. With the casing expanded, the stop surfaces and the face surfaces of the casing are pressed onto one another by the tie rod.

  • Patent number: 9364878
    Abstract: The invention relates to a method, a computer program and a rolling mill train for cold rolling a metal strip (200). In order to achieve a shortening of undesired off-gauge lengths, the method according to the invention provides that the head (210) of the metal strip (200) already undergoes a thickness reduction at the first active rolling stand (n) in the rolling mill train, and then is transported on to the next rolling stand, in order to undergo a further thickness reduction there. The method according to the invention also provides for further reducing the initial pass thickness at the n-th rolling stand in accordance with the tensile stress that has built up in the meantime between the n+1-th and the n-th rolling stand.
