Abstract


Current domestic production of refined aluminum is still the main method used three liquid electrolytic refining method, but compared with other countries , China's three tons of liquid aluminum electrolytic refining to produce high 19000KWh around DC consumption , high energy consumption seriously hinder our three liquid electrolytic refining of development, largely restricting domestic production of refined aluminum . How to reduce energy consumption , and preferably the best industrial electrolyte component is the main purpose of this thesis . This thesis is to extensively reviewed on the basis of the relevant literature , for Shanxi Guan liquid aluminum electrolytic refining Corporation 70KA three specific conditions for the company through several experiments to explore the best fine aluminum electrolytic tank , the main research contents and conclusions are as follows: ( a ) by changing the AlF 3 -Na 3 AlF 6 -BaCl 2 -NaCl electrolyte Systems Na 3 AlF 6 and AlF 3 of the specific content of the sample was prepared in a muffle furnace , the use of \physical Property comprehensive tester \( 2 ) , combined with three liquid electrolyte aluminum electrolytic refining key requirement in the experimental group selected on the basis of several energy- electrolyte composition , mainly : 60% BaCl 2 -22% Na 3 AlF 6 -14% AlF 3 -4% NaCl and 60? Cl 2 -21% Na 3 AlF 6 -15% AlF 3 -4% NaCl two kinds .
