FURNACE MATERIAL DETECTION SYSTEM FOR A METAL MAKING LANCE

摘要

A fully automated system and method for rapidly and reliably detecting the ingestion of furnace material 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 furnace material is detected by the sensor. The inner wall of the lance tip is also preferably formed with a furnace material collecting reservoir for collecting ingested furnace material and directing it toward the temperature sensor for quick and reliable furnace material detection.
