Process for reusing slag of aluminum smelting furnace

Abstract

The invention belongs to the technical field of slag reutilization and particularly relates to a process for reusing slag of an aluminum smelting furnace. The process adopts the smelting furnace. Thesmelting furnace comprises a box body and further comprises a crushing unit, material guide units, a smelting chamber, a motor, a collecting box, a first pipe, a purifying unit and a controller. By the adoption of the process, on the one hand, in the process of mixing the aluminum slag and an aqueous solution of a sintering machine, the aluminum slag and the aqueous solution of the sintering machine are fully mixed to form blanks while being added and stirred; meanwhile, spray nozzles are used to spray water mist to the blanks during the pressurization and plasticity of the blanks, so that theblanks are tightly attached, no fracture occurs between the blanks during sintering in the sintering furnace, and thus the quality of a refractory blank is improved; and on the other hand, the formedrefractory blank is installed on the inner wall of the smelting chamber to prevent the smelting furnace from being damaged when aluminum metal is smelted, so that the service life of the smelting chamber is prolonged.

Description

technical field

[0001] The invention belongs to the technical field of slag reuse, in particular to a process for reusing slag of an aluminum smelting furnace. Background technique

[0002] Metal smelting is the process of changing non-ferrous metals from a compound state to a free state. Use carbon, carbon monoxide, hydrogen and other reducing agents to undergo reduction reactions with metal oxides at high temperatures to obtain metal elements. "China's rare earth metal smelting industry market prospect and investment strategic planning analysis report" pointed out that there are more than 200 enterprises engaged in rare earth mining, smelting and separation in the country, and they have been able to produce single rare earth oxides, single rare earth metals, rare earth salts, and rare earth alloys Rare earth products of more than 400 types and nearly a thousand specifications, such as rare earth functional materials, etc., and continue to extend to high value-added, refin...

[0042] As an embodiment of the present invention, the No. 1 hole 211 is provided with a grinding unit 7; the grinding unit 7 is used for grinding metal, and the grinding unit 7 includes a dust-staining plate 71 and a grinding block 72; The gray plate 71 is clamped on the side wall of the No. 1 hole 211 ; the grinding blocks 72 are discontinuously arranged on the dust staining plate 71 , and the grinding blocks 72 are fixedly connected to the dust staining plate 71 . A lot of dust is generated during the crushing of metals, and the dust falling into the smelting chamber 4 will affect the metal smelting, thereby reducing the effect of metal smelting; the present invention sets the grinding unit 7, on the one hand, the dust-stained plate 71 is clipped together On the side wall of the number hole 211, the dust produced in the metal crushing is adhered by the ash-staining plate 71, so as to avoid affecting the metal smelting due to the dust, thereby improving the metal smelting effe...
