Abstract: A fully automated system and method for rapidly and reliably detecting the ingestion of slag within the tip of a metal making lance. The system utilizes a temperature sensor disposed adjacent to the inner surface of the inner wall of a metal making lance tip. The sensor is in communication with a control station. The control station is preferably in operative communication with a valve for shutting off gas flow to the lance and, optionally, at least one alarm, a coolant fluid shut-off valve, and any other lance operation mechanisms as may be desired or necessary when slag is detected by the sensor. The inner wall of the lance tip is also preferably formed with a slag collecting reservoir for collecting ingested slag and directing it toward the temperature sensor for quick and reliable slag detection.

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.

Abstract: A water-cooled, bi-metal copper and steel furnace panel including one or more passageways for enabling gaseous and/or particulate matter to be discharged into a furnace vessel through the panel. The passageways may support metal treatment apparatus. The panel has a front plate made of copper and a rear plate made of steel. The front and rear plates are welded or otherwise joined to one another to define a water coolant passageway for cooling the front plate of the panel. An array of vanes is selectively securable to the inner face of the outer steel plate in any desired number and arrangement suitable to accommodate the gaseous/particulate matter discharge passageway(s) and the cooling requirements of the front plate.
