Abstract
The present invention relates to electrolyte for producing refined aluminum, and is especially aluminum-refining F-Cl electrolyte system. The F-Cl electrolyte system consists of barium chloride 55-65 wt%, cryolite 19-23 wt%, aluminum fluoride 13-17 wt% and sodium chloride 3-5 wt%. The F-Cl electrolyte system has reasonable formulation and ideal use effect, and can be used to obtain reasonable initial crystallizing temperature and lower electrolyte loss and avoid firing, electrolyte overflow, etc.
Description
Technical field
The present invention relates to refined aluminium and produce used ionogen, be specially refined aluminium fluorine chlorine system electrolyte.
Background technology
Three layers of electrolytic process are adopted in refined aluminium production usually, and its middle layer is a dielectric substrate.Refined aluminium is produced used ionogen and is divided into two kinds of systems: fluorine chlorine system and pure fluorine system.The most of enterprise of China uses fluorine chlorine system electrolyte.Whether accurately, rationally used electrolytical prescription is directly connected to the quality of refined aluminium.The unreasonable meeting of ionogen proportioning causes phenomenons such as burning with anger, turn over ionogen.Existing refined aluminium production is all more not satisfactory than effect with electrolysis plasmogamy.
Summary of the invention
The present invention solves existing refined aluminium and produces the not satisfactory problem of used ionogen result of use, and a kind of reasonable ratio, result of use ideal refined aluminium fluorine chlorine system electrolyte are provided.
The present invention adopts following technical scheme to realize: refined aluminium fluorine chlorine system electrolyte, comprise bariumchloride, sodium aluminum fluoride (hexafluoro closes aluminium three sour sodium), aluminum fluoride, sodium-chlor, and the weight percent of above-mentioned component is:
Bariumchloride: 55-65% sodium aluminum fluoride: 19-23%
Aluminum fluoride: 13-17% sodium-chlor: 3-5%
All be powdery under the above-mentioned each component normality, get final product after they are mixed by above-mentioned proportioning.
The invention provides a kind of prescription rationally, effect comparatively the production of ideal refined aluminium with ionogen (prescription).Phenomenons such as ionogen can effectively be avoided burning with anger, be turned over to the ionogen of this kind prescription; Can obtain comparatively reasonably liquidus temperature; Can reduce refined aluminium liquid unit consumption.
