Publication number: 20180340734Abstract: The invention relates to an electric arc furnace and a method for operating same. The electric arc furnace comprises a lower vessel and a lid 120 placed on said lower vessel. The lower vessel has a tapping device for tapping molten metal. At least one electrode protrudes through the lid into the interior of the electric arc furnace, said electrode being held by an electrode holding device. A supply voltage device 150 is provided for supplying an electric direct current or alternating current to the electrode 130. The aim of the invention is to allow a continuous operation of the electric arc furnace. This is achieved in that the electrode holding device has an electrode adjusting device for adjusting the electrode dependent on the wear of the electrode and an electrode nippling device for nippling the electrode during the operation of the electric arc furnace.Type: ApplicationFiled: April 13, 2018Publication date: November 29, 2018Inventors: Guido Kleinschmidt, Jan Bader, Klaus Schmale, Rolf Best, Alexander Bergs, Thomas Henkel, Detlef Strieder, Peter Starke, Markus Ertl, Juergen Kunze

Patent number: 7998400Abstract: A gas supply system for a side blowing and/or bottom blowing metallurgical furnace with at least one tuyere which is mounted in the side wall and/or in the bottom of the furnace, wherein gas is conveyed through a line of the gas supply system to the tuyere and through the tuyere to the interior of the metallurgical furnace and emerges there in the form of bubbles. The gas supply system has an inflow restrictor which is assigned to the tuyere or is positioned upstream of the tuyere and reduces or interrupts the gas supply to the interior of the furnace at equal intervals of time.Type: GrantFiled: January 17, 2009Date of Patent: August 16, 2011Assignee: SMS Siemag AktiengesellschaftInventors: Peter Heinrich, Manfred Schubert, Rolf Best

Patent number: 7871560Abstract: A metallurgical vessel having support brackets mounted on a vessel wall. The support brackets are mounted by a mounting system on a support body that does not completely surround the circumference of the vessel. The mounting system includes clamps that act on the support brackets. A coupling device is provided, which has, a first coupling component designed as a male part mounted on the support body and a second coupling component designed as a female part mounted on the vessel wall. The first and second coupling components are configured and arranged so as to automatically engage when the clamps are in the engaged position and to automatically disengage when the clamps are not in the engaged position. The coupling device has sealing elements and a coupling mechanism of the first coupling component relative to the second coupling component.Type: GrantFiled: December 19, 2005Date of Patent: January 18, 2011Assignee: SMS Siemag AktiengesellschaftInventors: Rolf Best, Wilhelm Köper, Telita Moreira Köper, legal representative, Marcel Fasswald, Lutz Rose
