Metallurgical plasma torch PM-125 is designed for heating and melting in a vacuum electrically
conductive materials and can be used, in particular, in:
- melting units with an extract of an ingot from a copper water-cooled crystallizer;
- induction-plasma melting and casting vacuum electric furnaces with a ceramic crucible equipped
with a hearth electrode;
- induction-plasma vacuum furnaces with a copper water-cooled sectioned crucible;
- Installations for crucible-free melting of mono- and polycrystalline ingots of refractory metals and
alloys.
