A device for continuous casting of rare earth metals

Abstract

The invention provides a rare-earth metal continuous furnace discharging and ingot casting device. The device comprises a high-temperature-resistant heat preservation box and a heater arranged in thehigh-temperature-resistant heat preservation box; a liquid metal discharge pipe is arranged at the bottom of the interior of the high-temperature-resistant heat preservation box; the high-temperature-resistant heat preservation box is provided with a siphon pipe where liquid metal is added; the heater is provided with an inclined heating surface, and the siphon pipe is located above the higher endof the heater; a pouring box is further included; the pouring box is filled with shielding gas; the pouring box is internally provided with a mold roller shaft conveying device; an ingot casting moldis arranged on the mold roller shaft conveying device; a metal collecting box is further arranged in the pouring box; and the liquid metal discharging pipe is inserted into the pouring box and is located above the mold roller shaft conveying device. Through cooperation of the pouring box and the high-temperature-resistant heat preservation box which are arranged, continuous furnace discharging and continuous casting are realized, and the technical problem that electrolyte is doped in metal due to the fact that heat supply is insufficient in the metal crystallization process is solved.

Description

technical field [0001] The invention relates to the technical field of ingot casting, in particular to a rare earth metal continuous furnace ingot casting device. Background technique [0002] At present, the rare earth oxide molten salt electrolysis method has become the main process for the preparation of rare earth metals. The electrolytic cells used by various production enterprises are also different, including 6KA, 7KA, 8KA, 10KA and above 10KA, but the rare earth metal ingot casting methods are also different, including manual ingot casting and simple siphon ingot casting. Artificial ingot casting increases the labor intensity of workers, and long-term roasting at high temperature (900-1000°C) in front of the electrolytic furnace will have a certain impact on human health. Some rare earth enterprises have carried out research on simple siphon ingot casting technology, which can only siphon cast metal in a single furnace, and cannot operate continuously. A layer of ra...

Problems solved by technology

Artificial ingots increase the labor intensity of workers, and they are roasted at high temperature (900-1000°C) in front of the electrolytic furnace for a long time, which will have a certain impact on human health

Some rare earth enterprises have carried out research on simple siphon ingot casting technology, which can only siphon cast metal in a single furnace, and cannot operate continuously. A layer of rare earth molten salt electrolyte is attached to the metal surface, and follow-up treatment is required; Due to the influence of metal heat during the ingot, the metal crystallization is not good, the metal surface is not smooth, and the subsequent treatment is not easy
