Metal making lance with disposable sensors

摘要

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.
