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.
Claims23
A metal making lance assembly comprising:
- a barrel;
- a tip attached to said barrel, said tip including at least one nozzle for discharging at least one of gaseous and particulate metal treatment material into a metal treatment vessel;
- and
- a sensor feed tube carried by said barrel and adapted to accommodate passage of at least one disposable sensor, said sensor feed tube being separate from and isolated from fluid communication with said at least one nozzle.
