[0002] Rare earth electrolytic furnace is an important equipment used in the production of rare earth metals. It is usually composed of cathode rack, anode, electrolyte and power supply. Among them, the cathode rack is one of the key components of the electrolytic furnace. It supports the cathode metal plate and is subjected to high temperature and current during the electrolysis process. The cathode rack is usually made of high temperature resistant and conductive materials, such as molybdenum, copper or tungsten.

[0003] In the prior art, the cathode metal plate used in the electrolytic furnace is usually large in size and heavy in weight. When the cathode metal plate is fixed by the cathode frame, the center part of the cathode is usually clamped to ensure that the cathode metal plate maintains a balanced center of gravity during the lifting process, and avoids the cathode metal plate from being clamped unsteadily due to tilting during the lifting process. However, before the cathode metal plate is fixed, it is troublesome to find the center point of the cathode. Therefore, a rare earth electrolytic furnace fast lifting cathode frame is proposed to solve the above problems. Utility Model Content
