N2 - Heterophase salt fluxes are mixtures of liquid salts and solid phases. The liquid phase provides for full surface coverage of the metal being protected from the influence of aggressive gaseous phase components. Solid phases retard the reagent delivery and the products withdrawal through the flux layer. This allows less salt consumption and improves protective flux properties. Technological features of heterophase fluxes depend greatly on their structure. There are several approaches to the structure formation: Mechanically mixing certain proportions of salt mixtures and solid phases of definite coarseness, the former being indifferent to the latter and to the metal being protected. A mechanical heterophase flux is a porous plate made of material indifferent to metals and soaked with a liquid salt. Introduce the salts into fluxes. The salts should be easily hydrolyzed and vaporized and must also easily interact either with the gas atmosphere or the metal protected. This composition and structure of the first two methods remain stable with time while in the last method it changes with time and can be formed in accordance with a program. The heterophase flux production technology based on the usage of waste electrolyte from magnesium electrolyzers has been designed. The flux has been tested and the high temperature has been reduced tenfold and considerable amount of metallic zinc has been saves, both factors contributing to environmental protection.
