Rare earth smelting scene

Rare earth smelting process is mainly divided into pyrometallurgy and hydrometallurgy; Rare earth metal preparation by electrolytic method (molten salt electrolysis) or metal thermal reduction method (such as calcium-thermal reduction). Pyrometallurgy includes the preparation of rare earth alloys by the silicon thermal reduction method and the high-temperature smelting technology, which is applicable to the direct extraction of rare earth metals.

Rectification power supply for rare earth smelting

The product strictly complies with GB 29435-2012 "Unit Product Energy Consumption Limit of Rare Earth Smelting", has voltage/current control, soft start protection, cold furnace start voltage of 40-60V, hot furnace automatically switch to 8-12V to avoid impurities penetration, overvoltage/overcurrent/overheating/phase loss protection, intelligent display of fault code. This product is equipped with PLC and touch screen, and intelligent monitoring module can be selected to realize declared data acquisition and process optimization. Water-cooled heat dissipation system can be configured, which is suitable for 50 ° C high temperature environment and ensures continuous operation of equipment for 24 hours.
