Patent number: 7958930Abstract: The invention relates to a wall (100) of a casting die for casting a molten metal. Die walls comprising a front plate (110) with a pocket borehole (112) and a rear plate (120) with a transversal borehole (122) aligned with the pocket borehole, on the cold side of the die front plate, are known in prior art. The aim of the invention is prevent the entrance of cooling liquid from the transition region (115), between the front plate (110) and the rear plate (120), into the pocket borehole (112) or the transversal borehole (122). To this end, a sealing element (140) having a longitudinal borehole is arranged in the transition region (115) in such a way that the longitudinal borehole of the sealing element is at least approximately aligned with the transversal borehole (122) in the rear plate of the die and the pocket borehole (112) in the front plate of the die.Type: GrantFiled: December 11, 2007Date of Patent: June 14, 2011Assignee: SMS Siemag AktiengesellschaftInventors: Gereon Fehlemann, Albrecht Girgensohn, Jörn Hoffmeister

Patent number: 7798202Abstract: A broadside (100) for the broadside of a funnel mold for the casting of metal. Known broadsides of this kind have at least one groove-shaped cooling channel (110) in the backside (R) of the broadside. Adjacent the cooling channel (110) on the backside of the broadside, recesses (A1, . . . , A5) are provided as well as filler elements (140-1, . . . , -5) for the at least partial sealing of the recesses. In order to constructively simplify the broadside in view of the adjustment of a generally constant flow rate of a cooling medium through the cooling channel, it is proposed to design the recesses (A1, . . . , A5) in such a way, that they cross the cooling channel (110) diagonally to its longitudinal direction. Moreover, the recesses (A1, . . .Type: GrantFiled: August 30, 2006Date of Patent: September 21, 2010Assignee: SMS Siemag AktiengesellschaftInventors: Hans Streubel, Jörn Hoffmeister, Markus Reifferscheid, Gereon Fehlemann, Thomas Lamberti

Publication number: 20100084108Abstract: A continuous casting mold with two narrow mold sides opposite one another and two longitudinal mold sides opposite one another. At least one of the narrow mold sides is movable toward and away from the other by means of hydraulic cylinders on the opposite narrow mold side. The hydraulic cylinders can be actuated independently from one another and have, in each instance, a cylinder and a piston guided therein. The piston rod of the piston is connected to the narrow mold side that is to be displaced, and a device for acquiring the position of the piston and, therefore, the displacement of the narrow mold side, is associated with at least one of the hydraulic cylinders. To improve the determination of the position of the narrow mold side, a displacement measuring system is arranged parallel to the hydraulic cylinder and constructed such that its measurement path directly corresponds to the displacement of the piston of the hydraulic cylinder.Type: ApplicationFiled: March 26, 2008Publication date: April 8, 2010Applicant: SMS Siemag AGInventors: Jörn Hoffmeister, Alfons Krausa

Patent number: 7497244Abstract: The invention relates to a device for supporting and oscillating a continuous casting mold (1) for continuously casting molten metals, particularly molten metal materials, comprising: guide elements (4) symmetrically arranged on both sides of the central longitudinal axis (2) of the casting; fixed supporting parts (5), and; a continuous casting mold (1) supported on paired oscillating devices (6). The inventive device facilitates the accessibility to individual modules for maintaining and/or eliminating damages. To this end, a module (7) that, itself, can be removed, is formed from paired bearing blocks (9) with guide elements (4) and with a supporting casing (7a) connected to said bearing blocks. The module is placed upon a stationary submodule (7b) and detachably connected thereto.Type: GrantFiled: June 7, 2005Date of Patent: March 3, 2009Assignee: SMS Demag AGInventors: Erich Hovestädt, Martin Becker, Axel Weyer, Axel Stavenow, Jörn Hoffmeister

Patent number: 7490655Abstract: A device for the support and oscillation of a continuous casting mould (1) for casting liquid metal, particularly liquid steel, comprising guide elements (4) which are mounted on fixed carrier components (5) and which is actually by means of oscillation devices (6). In order to shorten time required for mounting and dismounting and therefor to lower the down times and costs of said continuous casting device, a first module (7) is made of guide elements (4) and carrier components (5) and a second module (8) consists of the oscillation device (6). The second module (8) can be dismantled via an outlet (9) which extends laterally, perpendicular to the plane of symmetry (2) below the guide elements (4) or in between guide elements (4). Each of the two modules (7,8) can be dismounted or re-mounted in a manner which is temporally and locally independent from the other respective module (7,8).Type: GrantFiled: June 16, 2005Date of Patent: February 17, 2009Assignee: SMS Demag AGInventors: Thomas Lamberti, Axel Stavenow, Jörn Hoffmeister, Jürgen Müller, Axel Weyer
