Patent number: 9574247Abstract: In a method and a device for operating a smelting reduction process, at least part of an export gas from a blast furnace or a reduction unit is thermally utilized in a gas turbine and the exhaust gas of this gas turbine is used in a waste heat steam generator to generate steam. The remaining part of the export gas is fed to a CO2 separation apparatus, the tail gas thereby obtained being fed to a waste heat steam generator and burned for additional steam generation. The combustible components of the tail gas are sent for thermal utilization in a steam generator, so that the overall energy balance of the thermal use of the export gas is improved. In addition, a further part of the export gas is qualitatively improved by the CO2 separation apparatus, so as to generate a high-quality reduction gas which can be supplied for metallurgical use.Type: GrantFiled: August 21, 2014Date of Patent: February 21, 2017Assignee: PRIMETALS TECHNOLOGIES AUSTRIA GMBHInventors: Robert Millner, Johannes Leopold Schenk, Kurt Wieder

Patent number: 9181594Abstract: A process for producing pig iron or liquid primary steel products in a smelting unit (1), in particular a melter gasifier. Iron-ore-containing charge materials, and possibly additions, are at least partially reduced in at least one reduction unit (R1, R2, R3, R4) by means of a reducing gas. A first fraction of the at least partially reduced charge materials is melted down in the smelting unit (1), while carbon carriers and oxygen-containing gas are supplied, with the simultaneous formation of the reducing gas. The reducing gas is fed to the reduction unit (R1, R2, R3, R4) and, after the reducing gas has passed through the reduction unit, it is drawn off as top gas. A second fraction of the at least partially reduced charge materials is fed to a smelting reduction unit for reducing and smelting.Type: GrantFiled: September 25, 2013Date of Patent: November 10, 2015Assignee: SIEMENS VAI METALS TECHNOLOGIES GMBHInventors: Christian Boehm, Jan-Friedemann Plaul, Johannes Leopold Schenk

Patent number: 9139884Abstract: A process and an apparatus for producing liquid pig iron or liquid primary steel products from charge materials formed by iron ores and additions. The charge materials are subjected to a further reduction in a reducing zone (1) and are then fed to a smelting zone or a smelting unit (2), in particular a fusion gasifier, for smelting with the addition of carbon carriers and oxygen-containing gas to form a fixed bed. A CO- and H2-containing reduction gas is formed, which gas is introduced into the reducing zone converted there and drawn off as top gas. The hot top gas, laden with solid matter, after separation of the solids, is subjected at least to a dry coarse separation and at least parts of the hot solids segregated by the separation are returned into the smelting zone or the smelting unit (2) or the reducing unit (1). In addition, the top gas is treated in a further fine separation stage (13A).Type: GrantFiled: January 30, 2009Date of Patent: September 22, 2015Assignee: PRIMETALS TECHNOLOGIES AUSTRIA GMBHInventors: Georg Aichinger, Thomas Eder, Hado Heckmann, Robert Millner, Johannes Leopold Schenk, Martin Schmidt, Kurt Wieder, Johann Wurm

Patent number: 8665437Abstract: A method for controlling a transformation process in which the conversion of charge materials to a product takes place along a transformation interface from the crystal and/or grain and/or phase and/or pore surface into the charge material, wherein one or more chemical elements in the charge materials is released and/or incorporated and/or rearranged and wherein the conversion of the charge materials takes place along advancing transformation interfaces. The charge materials are identified on the basis of at least one optical, in particular microscopic, analysis with respect to their phases and/or phase components and/or their phase morphology, structure, texture and/or their chemical composition. On the basis of these variables, reference functions for the charge materials, which describe the conversion of the charge materials in the process, are assigned and used for establishing the process parameters of the transformation process.Type: GrantFiled: May 7, 2009Date of Patent: March 4, 2014Assignee: Siemens Vai Metals Technologies GmbHInventors: Harald Fischer, Heinrich Rochus Mali, Johannes Leopold Schenk, Stefan Schuster, Bernhard Hailu Spuida, Kurt Wieder, Franz Winter

Patent number: 8540931Abstract: An injector insert pipe is arranged in the gas channel of a nozzle for injecting oxygen-containing gas into a pig iron production unit, wherein an interspace which surrounds the pipe is present over the entire pipe length between the wall of the gas channel and the pipe outer wall. The pipe extends at least as far as the nozzle end face which contains the mouth of the gas channel. The pipe space is connected to an oxygen-containing gas feed line, and the interspace is connected to a protective gas supply line. In a process, oxygen-containing gas is fed into the pipe space, which after it has flowed through the pipe, enters the production unit at an entry velocity, and the interspace is simultaneously flowed through by a gas which exits into the production unit at an exit velocity, wherein the entry velocity is greater than the exit velocity.Type: GrantFiled: November 5, 2009Date of Patent: September 24, 2013Assignees: Siemens Vai Metals Technologies GmbH, Siemens AktiengesellschaftInventors: Georg Aichinger, Franz Berner, Stefan Lechner, Marinko Lekic-Ninic, Jan-Friedemann Plaul, Johannes Leopold Schenk, Martin Schmidt, Thomas Söntgen, Bogdan Vuletic, Kurt Wieder, Johann Wurm
