Recently, China and global's largest rare earth alloys and rare earth metal materials: rare earth metal neodymium and praseodymium-neodymium alloy manufacturer BTRX rare earth alloy technology company, successfully developed a new Wanan electrolytic cell, the electrolytic cell is 2.2 meters long and 1.8 meters wide. 1 meter high.
"We put the fluoride salt solution in the electrolytic cell and passed 15,000 amperes of direct current. The furnace temperature was maintained at about 1000 ° C, and then the rare earth praseodymium-neodymium oxide was poured into the electrolytic cell. The reduction of rare earth ions to the cathode into metal droplets dripped out from the thin tube below. "Guo Haitao, a senior engineer of the company's research and development team, said while pointing to us.
Guo Haitao admitted that the difficulty in the development of the Wanan electrolytic cell lies in the molten salt electrolysis process. The high-temperature molten fluoride salt system used has a very strong erosion ability, and it is the key to find suitable tank materials and tool accessories.
At present, China's praseodymium-neodymium alloy manufacturers' praseodymium-neodymium alloy products mainly use the production technology of 6 thousand amperes of small electrolytic cells. The R & D team of BTRX has been intensively cultivating rare earth metal electrolysis cells and electrolysis technology. From 6,000 amp small electrolysis cells to 30,000 amp large electrolysis cells, industrial tests have been carried out, and the final production process is locked to the 15,000 ampere electrolysis cell process technology.
Rare earth metal neodymium and praseodymium-neodymium alloy products are the key raw materials for the production of suitcase buttons, mobile phone accessories at home and abroad, as well as the original magnetic materials used in the field of wind turbines and aerospace. Its stability directly affects the stability of the application of magnetic materials accessories. Sex.
The 15,000 ampere rare earth molten salt electrolysis technology adopted by the company not only has high single furnace output, long furnace age and low power consumption, but also has consistent products. It is highly praised by users at home and abroad, "Our process technology continues to develop and advance and has been leading The development direction of rare earth metal electrolysis technology at home and abroad. "Guo Haitao said confidently.
At present, the enterprise has achieved an industrial scale with an annual output of 8,500 tons and an output value of more than 3 billion.
