The Immersion Lance has been designed for Positherm and Celox®.
The Celox” Lance features unique possibility of being applicable for Positherm® also.
The Immersion Lance connects the measuring probe with the
instrument.
In both cases the contact block consists of a replaceable tip which can be changed in a few minutes.
Interior cable can be glass fiber insulated compensation wire but a better solution is mineral insulated copper sheathed wire which for Celox® measurement is obligatory.
For heavy duty conditions and also in locations where no telescopic oversleeves for lance protection can be used we recommend the use of an interior extension pipe. The small diameter of our disposable probe allows the complete unit to be constructed in 3/4″ tube and to remain easy to handle.
Hardware and parts for the Immersion Lance can be ordered as separate items.
Sealed contact block mounted in a steel tube with split pin for mounting in the lanceholder.

Monolithic emergency lances for purging the molten metal with argon/Nitrogen. MMC commitments the manufacturing of these lances from high quality refractory castable having highest level of strength, resistance to temperature changes, anti-corrosion properties. This lance can be used alone or together with ladle bottom purging plugs. The use of lances can qualitatively improve the homogeneity and the steel quality
