FIELD: metallurgy. ^ SUBSTANCE: procedure consists in charging solid salt into heated tank, in pouring melt water-free carnallite on surface of solid salt, in mixing and heating produced mixture, in charging calcium fluoride and in extracting produced flux from tank. As solid salt there is used sodium bromide. Produced melted mixture is stirred with dry compressed air to complete dissolution of sodium bromide. Upon calcium fluoride loading produced melted mixture is again stirred with dry compressed air. Produced flux contains the flowing composition of components, wt %: 20-40 MgCl2, 10-30 NaBr, 2-10 CaF2, 30-35 KCl, 5-10 NaCl. ^ EFFECT: production of flux of uniform structure due to usage of solid sodium bromide with lower melting temperature instead of barium chloride. ^ 7 cl |
