Patent number: 6155332Abstract: In a process for continuously casting a metal strand by casting metal into a straight, vertically oriented mold and subsequently drawing off the strand formed in the mold, the straight strand at first is bent into a circular arc shape in a bending zone along a transition curve, is guided along a circular arc guide and finally is straightened in a final straightening zone along a transition curve and, after this, is extracted via an approximately horizontal straight guide.Type: GrantFiled: January 28, 1999Date of Patent: December 5, 2000Assignees: Voest-Alpine Industrieanlagenbau GmbH, Sollac-FosInventors: Heinz Hodl, Michael Stiftinger, Andreas Eichinger, Kurt Engel, Jean-Francois Marioton, Gerard Zurita, Vincent Guyot, Catherine Lopes

Patent number: 5577548Abstract: In continuous casting in a continuous casting plant, a strand (2) after emergence from the mold (1) is reduced in thickness by a wedge-shaped roller gap. In order to assure upon the casting to obtain the shortest possible wedge-shaped solidified head piece (25) or in the event of an interruption in casting or a decrease in the operating casting speed a short completely solidified strand intermediate piece of a thickness (28) differing from the desired final thickness (26) of the strand, the strand (2) is reduced in thickness exclusively in a region in which it has a liquid center (20), support segments (4, 5) being so directed at all times that the liquid tip (19) of the liquid center (20) always lies in a region of the strand guide in which the roller gap developed by the rollers (8) is the narrowest parallel gap--with respect to the following strand guide and disregarding a roller adjustment which follows the shrinkage of the completely solidified strand.Type: GrantFiled: October 13, 1994Date of Patent: November 26, 1996Assignee: Voest-Alpine Industrieanlagenbau GmbHInventors: Gerald Hohenbichler, Kurt Engel, Andreas Kropf

Patent number: 5489778Abstract: Materials are exposed to laser energy, and after the material is heated, the thermal radiation of the material is measured. Following this, a material-specific evaluation takes place, based on optical and thermal material properties. At least one area on the surface of the material to be identified is subject to a short, point-shaped exposure of laser radiation. The material-specific thermal impulse response for the radiated surface area of the material is both locally and temporally measured, and evaluated as regarding the kind of material.Type: GrantFiled: November 18, 1993Date of Patent: February 6, 1996Assignee: Laser Zentrum Hannover e.V.Inventors: Ingo Burmester, Kurt Engel

Patent number: 5115857Abstract: With known strand guides, the adjustment of different strand thicknesses involves cumbersome manipulations and the susceptibility to failures of the elements allowing for such adjustment. In order to eliminate such disadvantages, the framework parts of the strand guide rest one above the other by supports and counter supports equipped with supporting surfaces provided at different high levels and with counter supporting surfaces, respectively. In addition to the support and counter support, a rotary bushing having a helicoidal supporting surface is arranged in series to each support and counter support. An abutment allocated to one of the framework parts is supported on the rotary bushing.Type: GrantFiled: July 5, 1991Date of Patent: May 26, 1992Assignee: Voest-Alpine Industrieanlagenbau G.m.b.H.Inventors: Armin Schertler, Josef A. Ortner, Werner Scheurecker, Kurt Engel

Patent number: 5050666Abstract: An oscillation gear for a mold of a continuous casting plant includes an eccentric shaft and an eccentric sleeve surrounding the eccentric shaft and rotatable and fixable relative to the same. in order to provide for a space-saving structure requiring only few mechanically moving parts, both the eccentric shaft and the eccentric sleeve are each provided with at least one groove. The longitudinal axis of at least one of the grooves is oriented at an angle relative to the longitudinal axis of the eccentric shaft or eccentric sleeve, respectively. The longitudinal axes of the two grooves enclose an angle with each other. A force transmission element rotating commonly with the eccentric shaft or with the eccentric sleeve projects into each groove, the force transmission elements being mutually coupled.Type: GrantFiled: June 8, 1990Date of Patent: September 24, 1991Assignee: Voest-Alpine Industrieanlagenbau GmbHInventor: Kurt Engel

Patent number: 4546547Abstract: A checking and aligning stand for measuring and aligning structure sections of the strand guide of a continuous casting plant includes measuring surfaces to determine the mounting position of the structure section. In order to be able to effect a quick check of the mounting position of curved structure sections of a bow-type continuous casting plant without impeding the casting operation during this adjustment work, at least two pairs of measuring surfaces arranged at an angle to each other, preferably at 90.degree., to determine the roller-way coordinates relative to the position-defining supporting surfaces of the structure section are provided on the checking stand.Type: GrantFiled: August 19, 1982Date of Patent: October 15, 1985Assignee: Voest-Alpine AktiengesellschaftInventors: Werner Scheurecker, Alois Scheinecker, Johannes Cordella, Kurt Engel

Patent number: 4544015Abstract: A continuous casting plant includes supporting elements following a through-type mould and including the strand guideways. The elements are arranged within a cooling chamber and are fastened to a supporting structure so as to be adjustable relative to the through-type mould and relative to one another in the direction transversely to the longitudinal axis of the strand guideways. In order to be able to carry out an aligned adjustment between the mould and the supporting elements in a simple manner, with little work to carry out and even with the plant in operation, wherein the entry of the cooling chamber is avoided, at least one of the supporting elements is coupled with an adjustment means. This adjustment means is fastened to a supporting structure, directed outwardly from the cooling chamber and actuatable from outside of the cooling chamber.Type: GrantFiled: January 5, 1983Date of Patent: October 1, 1985Assignee: Voest-Alpine AktiengesellschaftInventors: Werner Scheurecker, Karl Holzer, Kurt Engel, Hermann Schubert

Patent number: 4532981Abstract: There is disclosed a continuous casting machine for selectively casting a strand having slab cross section or at least two strands having smaller cross sections. It includes a plate mold surrounded by a support frame supporting the end walls and side walls, and further intermediate end walls provided between the end walls for casting at least two strands. In order to provide end walls that are insertable into the mold and positively connectable thereto with parts that project into the mold used for slab cross sectional formats being avoided, a hollow body carrying copper plates of the intermediate end walls is inserted between the copper plates of the side walls. A coolant flows through the hollow body, which is supported with its upper end on the side walls by supporting elements overlapping the side walls, and with its lower end is fixed by coolant supply and discharge piping.Type: GrantFiled: June 3, 1983Date of Patent: August 6, 1985Assignee: Voest Alpine International Co.Inventors: Reinhard Hargassner, Thomas J.
