Patent number: 7537724Abstract: The invention relates to a cooling plate made of copper or a low-alloy copper alloy for metallurgic furnaces provided with high-strength sheet steel on the outside of the furnace. Said cooling plate has at least one, preferably at least two, coolant channels which extend inside the cooling plate, whereby coolant tube pieces used for feeding the coolant and discharging said coolant extend through the high-strength sheet steel of the furnace and are guided in an outer direction. Retaining tubes are arranged on the cooling plate and are provided with retaining disks which are arranged outside the high-strength sheet steel of the furnace and which fix the cooling plate in the direction of the inside of the furnace. The retaining tubes and retaining disks are preferably made of steel.Type: GrantFiled: July 14, 2003Date of Patent: May 26, 2009Assignee: Siemens Vai Metals Technologies GmbH & Co.Inventors: Wilhelm Stastny, Herbert Scharinger, Walter Rainer Kastner

Patent number: 6511629Abstract: The invention relates to a shaft furnace, in particular a direct-reduction shaft furnace, with a charge composed of particulate material, in particular a particulate material containing iron oxide and/or sponge iron, the said material being capable of being fed into the shaft furnace from above, and with, arranged in one plane, a multiplicity of gas-inlet orifices for a reduction gas in the region of the lower third of the shaft furnace, the shaft contour having a diametral widening and a cavity being formed between the gas-inlet orifices and the charge. The shaft furnace according to the invention makes it possible to supply gas to the shaft furnace so as to be distributed uniformly over its circumference.Type: GrantFiled: April 11, 2001Date of Patent: January 28, 2003Assignee: Deutsche Voest-Alpine Industrieanlagenbau GmbHInventors: Leopold Werner Kepplinger, Rainer Walter Kastner, Kurt Wieder, Wilhelm Schiffer, Wilhelm Stastny

Patent number: 6391249Abstract: A device for producing sponge iron from iron oxide lumps consists of a reduction shaft in which a hot dust laden reducing gas is delivered. The gas is produced in a gas generator by means of partial oxidation of solid carbon carriers and passes into the lower end of the reduction zone via lateral reduction gas inlets. The iron oxide lumps are fed to the upper area of the reduction shaft and are radially fed as sponge iron to the lower end of said reduction shaft via delivery organs. The delivery organs are arranged in such a manner that the sponge iron is conveyed only radially outwardly.Type: GrantFiled: April 3, 2000Date of Patent: May 21, 2002Assignee: Deutsche Voest-Alpine Industrieanlagenbau GmbHInventors: Hado Heckmann, Georg Schleich, Wolfgang Guenther, Kurt Wieder, Wilhelm Stastny

Patent number: 6213762Abstract: The invention relates to a shaft furnace (1), particularly to a direct-reduction shaft furnace, with a bed (2) of lumpy material, particularly lumpy material containing iron oxide and/or sponge iron, with discharge devices (4) for lumpy material which are located above the bottom area (3) of the shaft furnace (1), as well as with inlet ports (6) for a reduction gas which are arranged above the discharge devices (4). Arrangements (7) for moving the material in the shaft furnace (1) are located between the area formed by the inlet ports (6) and that formed by the discharge devices (4).Type: GrantFiled: January 14, 2000Date of Patent: April 10, 2001Assignee: Deutsche Voest-Alpine Industrieanlagenbau GmbHInventors: Ernst Eichberger, Wilhelm Stastny

Patent number: 5271609Abstract: In a plant including a shaft, which, in its upper end region, includes a gas exhaust device and a charging arrangement for continuously charging bulk material, a temperature measuring device for measuring the temperature of the gas emerging from the bulk material is provided. In order to ensure the uniform treatment of the bulk material, i.e., a uniform gas passage through the same over the entire cross section of the shaft at little structural expenditures, several temperature measuring devices are provided in the upper end region of the shaft, distributed in a cross sectional plane, and the charging arrangement includes several tubular mouth pieces for forming at least one conical pile within the shaft, which are adjustable relative to the shaft cross section in the radial direction.Type: GrantFiled: May 27, 1992Date of Patent: December 21, 1993Assignee: Voest-Alpine Industrieanlagenbau GmbHInventors: Leopold W. Kepplinger, Wilhelm Schiffer, Wilhelm Stastny, Bernhard Rinner

Patent number: 4678419Abstract: An arrangement for the production of vitrified slag includes a rotating cooling drum provided with an internal cooling and on whose surface molten-slag-receiving recesses are provided. The site of impact of the slag is approximately at the uppermost point of the cooling drum. In order to ensure the vitrification of the slag with the flowing of molten slag off the cooling drum being reliably prevented, and an economic production of solidified slag being ensured, the recesses are separated by webs in the circumferential direction of the cooling drum and in the end region of the cooling drum are designed to be closed in the axial direction thereof. A plurality of cooled counter rolls contacting the webs by their surfaces and aligned with their axes parallel to the cooling drum are provided. They are arranged after the site of impact of the slag in the rotation direction of the cooling drum and one behind the other in its circumferential direction.Type: GrantFiled: March 3, 1986Date of Patent: July 7, 1987Assignee: VOEST-ALPINE AktiengesellschaftInventors: Bernhard Enkner, Dietmar Stephani, Leopold Schropp, Wilhelm Stastny
