VACUUM REFINING FURNACE FOR NONFERROUS METAL MULTICOMPONENT ALLOYS

摘要

Disclosed is a high-power vacuum refining furnace which can be used for the purification of the multicomponent alloys. The evaporator coil laminates are covered by a refining furnace graphite insulation screen wherein a number of through-holes are cast. The graphite condensation jackets are of two or more different sizes with the minimum located in the outside of the graphite insulation screen and the bigger one located in the outside of the smaller one. Except the maximum condensation jacket, all the condensation jackets are equipped with a number of through-holes. The following advantages are present: 1) refining a variety of multicomponent alloys with low-cost vacuum distillation; 2) when the power of the graphite heater reaches 270 kw, the processing capability of certain alloys can be up to 25 metric tons per day; 3) less heat loss, high efficiency of evaporation and condensation; 4) long working life, low energy consumption, high metal direct yield, good, stable and reliable production environment.
