Magnesium electrolytic bath production line and magnesium ingot melting method

Abstract

The invention discloses a magnesium electrolytic bath production line and a magnesium ingot melting method in the technical field of magnesium electrolysis. The production line comprises a head groove, electrolytic baths and a separation groove connected in sequence through connecting channels; the multiple electrolytic baths are serially connected with each other; magnesium ingot frames capable of placing magnesium ingots are arranged in the connecting channels between the electrolytic baths; and an air pressure pump is arranged in the separation groove for conveying electrolyte melts in the separation groove into the head groove to form a circulating production line. The magnesium electrolytic bath production line and the magnesium ingot melting method have the following beneficial effects: the magnesium ingot frames are arranged in the connecting channels of the electrolytic bath production line, and the magnesium ingots are put in the magnesium ingot frames, so that redundant heat in electrolytes is used for melting the magnesium ingots; the molten magnesium flows into the separation groove for gathering along with the electrolytes, and is conveyed to sponge titanium reducing production procedures by a two-man ladle for direct reduction of titanium tetrachloride, so that the reducing production period is shortened, and the improvement of the sponge titanium production quality and the acceleration of stable and efficient operation of the production line magnesium electrolysis process are facilitated.

Description

technical field [0001] The invention relates to the technical field of magnesium electrolysis, in particular to a magnesium electrolytic tank assembly line and a method for melting magnesium ingots. Background technique [0002] In the production of sponge titanium, in order to realize the cycle of magnesium and chlorine, it is necessary to build a magnesium electrolysis process. The magnesium chloride produced in the reduction process is used as the raw material for electrolysis, and the magnesium produced by electrolysis is used to reduce the production of sponge titanium. When the assembly line magnesium electrolysis process is adopted, the electrolytic DC power can reach 200kA, and the electrolyte temperature is controlled at 670-710°C. According to the principle of electrolysis, high electrolyte temperature is not good for electrolysis production. When the electrolyte composition and the electrolytic cell are normal, it is usually necessary to appropriately reduce the e...
