Combined Oxygen Blowing/Fuel Burner Lance Assembly

US Patent:
5635130, Jun 3, 1997
Filed:
Jun 7, 1995
Appl. No.:
8/485306
Inventors:
Theodore J. Leczo - Pittsburgh PA
Nicholas M. Rymarchyk - Baden PA
Gerald R. Glatz - Pittsburgh PA
Assignee:
Berry Metal Co. - Harmony PA
International Classification:
C22B 1500
US Classification:
266 47
Abstract:
An improved oxygen blowing/fuel burner lance assembly for introducing, at selected times, a flow of oxygen and/or carbonaceous fuel material, such as fine-grained carbon or hydrocarbon gas (e. g. , natural gas and the like), into an electric furnace vessel. The lance assembly includes a housing portion, a straight barrel having a first and connected to the housing portion and a second end connected to a lance tip. The lance tip includes a nozzle structure having at least one oxygen injection nozzle and at least one carbonaceous material injection nozzle which together define a burner assembly for dispensing a combined flow of carbonaceous fuel and oxygen from the lance which may be ignited to produce a flame for preheating a scrap charge in an electric furnace vessel. When the scrap is sufficiently melted through cooperation of the electric furnace electrodes and the burner, the oxygen and carbonaceous fuel material flows may be terminated to extinguish the burner flame, the oxygen flow may be restarted at a reduced flow rate to complete preheating/cutting (if necessary), or at a supersonic flow rate for refining/decarburizing of the molten steel bath.

Metal Making Lance Assembly

US Patent:
2004011, Jun 24, 2004
Filed:
Oct 24, 2003
Appl. No.:
10/693045
Inventors:
James Robins - Chicago IL, US
Theodore Leczo - Pittsburgh PA, US
George Koenig - Cranberry Township PA, US
Nicholas Rymarchyk - Baden PA, US
International Classification:
C21C005/32
US Classification:
266/225000
Abstract:
An assembly wherein inexpensive and essentially maintenance-free disposable sensors may be used in conjunction with a metal making lance. The assembly contemplates the use of disposable sensors that are accommodated by a sensor feed tube disposed interiorly or exteriorly of a conventional metal making lance. The sensors may be selected to detect one or more characteristics of the metal being treated and/or operating conditions of a metal treatment vessel.

Combined Forged And Cast Lance Tip Assembly

US Patent:
6217824, Apr 17, 2001
Filed:
May 20, 1999
Appl. No.:
9/315302
Inventors:
Theodore J. Leczo - Pittsburgh PA
Nicholas M. Rymarchyk - Baden PA
Stephen A. Manley - Butler PA
Peter J. Danek - Zelienople PA
Assignee:
Berry Metal Company - Harmony PA
International Classification:
C21C 532
US Classification:
266225
Abstract:
A lance tip assembly for a water-cooled lance as well as a method for constructing same. The lance tip assembly includes a first component of solid cast metal which is secured to a second or lower component of forged metal. Each active material discharge nozzle of the combined forged and cast lance tip assembly is constructed in part of the first cast component and in part of the second forged component. Only a single bond is required to join the first and second component at each nozzle site. The first and second components are fabricated to include structural features which individually and collectively promote high coolant water flow velocity through the lance tip and substantially uniform cooling of face of the lance tip.

Metal Making Lance With Disposable Sensors

US Patent:
2003022, Dec 11, 2003
Filed:
Jun 11, 2002
Appl. No.:
10/167711
Inventors:
James Robins - Chicago IL, US
Theodore Leczo - Pittsburgh PA, US
George Koenig - Cranberry Township PA, US
Nicholas Rymarchyk - Baden PA, US
International Classification:
C21C005/32
US Classification:
266/225000
Abstract:
An assembly wherein inexpensive and essentially maintenance-free sensor means may be used in conjunction with conventional a metal making lance with minimal adaptation of the lance's structure. The assembly contemplates the use of consumable sensors that may be dispensed through a sensor feed tube disposed interiorly or exteriorly of a conventional metal making lance. The sensors may be selected to detect one or more characteristics of the metal being treated and/or operating conditions of the furnace vessel.

Modular Lance

US Patent:
2004009, May 20, 2004
Filed:
Nov 19, 2002
Appl. No.:
10/299563
Inventors:
Theodore Leczo - Pittsburgh PA, US
International Classification:
C21C005/30
US Classification:
266/225000
Abstract:
A modular metalmaking lance having a pre-fabricated “plug-in” lower sections. The plug-in section is preferably of sufficient length to ensure that the joint between a plug-in section and an upper lance section is not in the area of the lance that typically is damaged in refining service. At the same time, the plug-in section is preferably short enough to be transported from an off-site assembly/repair shop to the refining shop via standard-length cargo trucks or truck-trailer rigs used throughout the world.
