Technology of fabrication of A1-alkali earth metals alloying compositions via electrolysis of chloride melt on liquid aluminum cathode

摘要

It is shown that Al-Sr-Ba triple alloyingcomposition is the best modifier of silumin type alloysand electrolysis of mixture of corresponding chloridesis the way of its fabrication. Electrolyzing bath linedinside by magnesite and containing graphiteanode,liquid aluminum cathode and additional ironelectrodes is using for this process. Technologicalscheme includes electrolyte preparation, metal facing,production of alloying composition and cleaning ofexhausting gases. Technical and economical parametersachieved during fabrication of pilot party of alloyingcomposition are presented.
