Patent number: 8763679Abstract: A casting roll for a two-roll casting device for the casting of metallic strip from a metal melt, in particular a steel melt, includes a roll body, on a casing surface of which a coating consisting of a coating material is applied by thermal spraying, which has a higher degree of hardness than the roll body. The casting roll according to the invention and the two-roll casting device, while easy to manufacture, has not only a long service life, but also allows for the manufacture of cast strips of optimum quality. This is achieved by the fact that the free surface of the coating, after thermal spraying, has a peak number RPc of at least 10 cm?1.Type: GrantFiled: January 24, 2008Date of Patent: July 1, 2014Assignee: Outokumpu Nirosta GmbHInventors: Ulrich Albrecht-Früh, Roland Sellger, Johann Wilhelm Schmitz, Reiner Kopp, Jörg Lauscher, Martin Franzke

Patent number: 8474294Abstract: The invention concerns a rolling stand, a rolling train, and a method for rolling a stepped preprofiled metal strip. In order to guarantee that the metal strip is free of waviness in its longitudinal direction, even after individual thickness reduction of the steps, the invention proposes that the thickness reduction be carried out on a step-specific basis according to the following mathematical relationship: ?hi/hi=?hi+1/hi+1=?=constant, where ?hi represents the amount of the thickness reduction in the region of the i-th step, and hi represents the value of the resulting thickness of the metal strip 200 after rolling in the region of the i-th step.Type: GrantFiled: May 2, 2007Date of Patent: July 2, 2013Assignee: SMS Siemag AktiengesellschaftInventors: Reiner Kopp, Hans-Peter Richter, Heinrich Röse

Patent number: 6662616Abstract: A method and a device for flexibly rolling a metal band by guiding the metal band through a roll gap formed between a first working roll and a second working roll, and by varying the size of the roll gap in such a way that band sections with a greater band thickness and band sections with a lesser band thickness are obtained over the length of the metal band. In the device and method, the time of contact between each point on the circumference of the first working roll and the metal band is shorter in duration than the time of contact between each point on the circumference of the second working roll and the metal band such that an asymmetric band thickness profile is obtained in a region of the band sections with a lesser band thickness.Type: GrantFiled: August 22, 2001Date of Patent: December 16, 2003Assignee: Muhr und Bender KGInventors: Peter Böhlke, Alexander Ebert, Andreas Hauger, Reiner Kopp

Patent number: 6602611Abstract: The invention relates to a multi-layer composite plates and to a method for producing multi-layer composite plates. Said multi-layer composite plates are comprised of two outer metallic slabs which serve as top and base plates and which are joined to a deformable connecting material located therebetween. The top and base plates are joined to the connecting material by means of a foaming adhesive which fills the cavities remaining in the composite. The cavities remaining in the composite are completely or partially filled by the adhesive. According to the method for producing multi-layer composite plates, adhesive is introduced between the layers to be joined, and the adhesive is subjected to a thermal treatment. The adhesive is completely or partially hardened during the thermal treatment. In the case of the partially hardened adhesive, the adhesive is completely hardened during an additional thermal treatment only after the multi-layer composite plate is reshaped.Type: GrantFiled: April 23, 2001Date of Patent: August 5, 2003Assignee: DaimlerChrysler AGInventors: Reiner Kopp, Arndt Gerick, Klaus Lempe-Nauer, Peter Winkler

Patent number: 6524408Abstract: To produce sheet steel components optimised for loading, a steel strip is cast between two cooled rolls with a variable nip and the thickness of the steel strip is changed by changing the time of contact between the strand shells and the rolls or by changing the cooling intensity of the rolls on the molten steel cast into the gusset formed by the rolls, thereby changing the thickness of the steel strip. Such a strip has a homogeneous structure and can subsequently be given a special quality by hot or cold rolling for its particular purpose of use.Type: GrantFiled: June 18, 2001Date of Patent: February 25, 2003Assignee: Thyssen Krupp Stahl AGInventors: Wilhelm Schmitz, Dieter Senk, Ulrich Albrecht-Früh, Reiner Kopp

Patent number: 5209211Abstract: Heating devices are used to prevent icing and deposition of fuel on the throttle valve under adverse operating conditions; these device comprise electrical resistance hot wires applied to the surface of the throttle valve, yet these wires lead to undesired turbulence in the fuel-air mixture flow. As the length of time in operation increases, the efficiency of the hot wires is lessened by corrosion of their surface. These disadvantages are avoided by integrating the heating device with the component to be heated. To this end, the heating device is disposed in an axial bore of the throttle valve shaft. This arrangement is used especially with mixture-compressing internal combustion engines equipped with carburetors or central injection systems.Type: GrantFiled: June 22, 1992Date of Patent: May 11, 1993Assignee: Robert Bosch GmbHInventors: Reiner Kopp, Albrecht Baessler, Peter Ropertz

Patent number: 5072606Abstract: A method of shaping planar parts which have an elastic and plastic range for making components which are curved two dimensionally around two axes under utilization of a high pressure peening shot beam comprises the steps of tension positioning the part to obtain through elastic deformation to obtain the desired contour; peening the surface of the part to be deformed by running a beam of shot along track lines which are essentially lines of equal strain in the parts to be made; controlling the peening shot beam energy such that more central parts receive shot at a higher energy than more peripheral parts of said part; repeating the aforementioned steps on the other side of the part; and separately peening shot treating at least some of thicker edge parts, so as to obtain plastic deformation.Type: GrantFiled: December 13, 1989Date of Patent: December 17, 1991Assignee: Dornier GmbHInventors: Winfried Koehler, Klaus-Peter Hornauer, Reiner Kopp, Klaus Baldner, Frank Wuestefeld

Patent number: 4967826Abstract: A process for producing metal parts in accordance with the principle of squeeze or forge casting wherein a permanent mold (2) is provided having a mold cavity, a seal (4) is placed on an upper edge flange (5) of the mold surrounding the cavity opening (6), liquid metal (9) is introduced into the cavity, an upper die (3) is inserted (7) into the cavity such that the level of the liquid metal is raised until the higher-level cavity created by the seal (4) is filled, the metal is at least partially solidified, and the final shape of the part is produced by pressing (9) in the upper die, with deformation and spreading of the seal. The result is a completely dense workpiece of excellent dimensional stability which has the texture of a forged part and is correspondingly of very high strength.Type: GrantFiled: October 4, 1989Date of Patent: November 6, 1990Assignee: Mannesmann Demag AktiengesellschaftInventors: Reiner Kopp, Klaus R. Baldner, Klaus Welschof

Patent number: 4788842Abstract: The invention relates to a method and apparatus for open-die forging of workpieces in forging presses at high forging temperatures, more particularly steel billets or ferrous alloy billets between about 800 and 1250 degrees Celsius. In conventional open-die forging it is often not possible to complete the forging process in a single heat, and the workpiece must therefore be reheated. Also, with direct contact between workpiece and tool, cracks occur, particularly in the vicinity of bulges, the prevention or straightening of which requires repeated transverse hammer- or pressure-forging, so lengthening the cooling time. The total energy consumption for deformation and heating of the workpieces is therefore relatively high.Type: GrantFiled: December 5, 1986Date of Patent: December 6, 1988Assignee: SMS Hasenclever Maschinenfabrik GmbHInventors: Reiner Kopp, Klaus-Rainer Baldner, Paul-Josef Nieschwitz
