An aluminium magnesium alloy joint refining device comprises a base, reduction annular tubes, electrolytic annular tubes and an aluminium magnesium alloy melting pot, wherein a heat insulation annulartube is mounted on each reduction annular tube in a sleeving manner; each reduction annular tube and the corresponding heat insulation annular tube are fixedly connected through a plurality of struts; two first annular sleeves are mounted on each electrolytic annular tube in a sleeving manner; two second annular sleeves are mounted on each heat insulation annular tube in a sleeving manner; a first through hole is formed in the side surface of each first annular sleeve; a second through hole is formed in the side surface of each second annular sleeve; a telescopic tube is arranged between eachfirst annular sleeve and the adjacent second annular sleeve; and one end of each telescopic tube is fixedly connected to the outer end of the corresponding first through hole. Through a skillful andsimple design, the aluminium magnesium alloy joint refining device skillfully combines the three functions of refining of aluminium metal, refining of magnesium metal and smelting of an aluminium magnesium alloy, so that the production efficiency is high. Backflow of different products is realized by the gravity. The aluminium magnesium alloy joint refining device is convenient to use.

Description

technical field [0001] The invention belongs to the field of metal smelting devices, in particular to an aluminum-magnesium alloy combined refining device. Background technique [0002] Magnesium alloy has the advantages of low density, good shock absorption, high stability, good electromagnetic shielding, good heat dissipation, and regeneration. It is an excellent structural and functional material and is widely used in national defense, aviation, aerospace, petroleum, chemical and other fields. Application, currently the most widely used magnesium alloy is magnesium aluminum alloy. The existing metal magnesia thermal reduction tanks are all designed for the Pidgeon method magnesium oxide-reductant solid-solid reduction reaction. The Pidgeon solid-solid reduction method has high heat energy consumption caused by too high reaction temperature (1200°C), so the reduction tank is used Short life (reduction tank replacement cost accounts for 1 / 4 of the total cost), and low puri...

Problems solved by technology

The existing metal magnesia thermal reduction tanks are all designed for the Pidgeon method magnesium oxide-reductant solid-solid reduction reaction. The Pidgeon solid-solid reduction method has high heat energy consumption caused by too high reaction temperature (1200°C), so the reduction tank is used Short life (reduction tank replacement cost accounts for 1 / 4 of the total cost), and low purity of crude magnesium; low reaction speed and raw material utilization rate caused by solid-solid reaction, slow temperature transfer during the reaction process, and a ball pressing workshop is required Disadvantages such as briquetting raw materials and waste of raw material heat obtained under high temperature conditions during the briquetting process; environmental pollution problems caused by reduction reaction slag that cannot be recycled (for every ton of magnesium produced, 6-7 tons of slag are produced); and Problems such as small output caused by non-continuous production

At present, the amount of magnesium metal is only 1% of that of metal aluminum. One of the important reasons is that the cost of refining magnesium metal is too high and the output is too small.

Magnesium alloys and their upstream products, metal magnesium and metal aluminum, need to be refined at relatively high temperatures, and the currently used alloy refining equipment cannot effectively utilize the waste heat generated in the upstream metal refining process, and the current equipment is difficult to achieve metal The ingenious combination of the three functions of aluminum refining, magnesium refining, and magnesium-aluminum alloy smelting, the production efficiency is low, and it is difficult to meet the demand for production capacity
