Description

Technical Field

[0001] The utility model relates to the technical field of refining furnaces, in particular to a refining furnace for fly ash ionization reduction products with environmental protection function. Background Art

[0002] Fly ash contains about 8% unburned carbon. According to rough calculations, the carbon slag in the electrolytic cell and the unburned carbon in the fly ash can just reduce aluminum, silicon and iron. According to the different specifications of aluminum silicon or aluminum silicon iron alloy produced, the difference in aluminum silicon iron content in the fly ash can be considered to adjust the addition ratio of fly ash and alumina powder. If aluminum silicon alloy is produced, the iron content may be high, and iron removal agent (borax flux, manganese chloride solvent) can be used for iron removal. If aluminum silicon iron alloy is produced, iron removal is not required. Other metal elements can be removed by high-temperature burning or adding refining agents and slag removal agents.

[0003] In order to remove impurities from the obtained metals, it is necessary to refine the elemental silicon, metallic aluminum or metallic iron. Refining requires the use of a refining furnace, which is a smelting equipment in the hot processing industry, and is mostly used in ferrous metallurgy for the final deoxidation and alloying of molten steel.
