VACUUM REFINING FURNACE

摘要

A vacuum refining furnace, including a furnace body, a graphite heater, an electrode, and a sealed furnace housing. The furnace body includes an evaporation laminate, a graphite condensing casing, and a graphite insulating casing. The evaporation laminate includes a plurality of evaporators. The evaporation laminate is nested within the graphite insulating casing, and the graphite insulating casing includes a plurality of through holes. At least two graphite condensing casings having different diameters are provided. The graphite insulating casing is nested within the graphite condensing casing having a smallest diameter, and the graphite condensing casing having a relatively small diameter is nested within the graphite condensing casing having a relatively large diameter. All the graphite condensing casings except for the graphite condensing casing having the largest diameter include a plurality of through holes.
