Description

Salt addition is introduced into discrete liquid particles by means of centrifugal sodium and alkaline earth metal fluorides individually or in forces with subsequent cooling of the formed combination. It is known that granules in the air provide magnesium, sodium and alkaline earth metal fluorides dissolved according to the invention in that those of the eye-less hygroscopic salts are in the addition of salts than analogous calorific components in such quantitative compounds. In addition, the fluorides, as they are known to have a smaller initial bond, increase the corrosion resistance of the magnesium temperature of the crystallization of the salt additive and magnesium alloys, while they form a thin fluoride protective film on the metal surface of the magnesium and a density of the salt additive up to 730 ° C, which is 0.9> to 1.2 times the density. But the use of a salt additive, best of the liquid magnesium or the magnesium alloy consisting only of fluorides, is made more difficult because it is in the same temperature range to ensure that the fluorides have a high melting temperature; In this case, the Fliehkraftgranulatur the end also with a treatment of the granules complicate the subsequent hydro chemical BeMagnesium or the magnesium alloy, because they are practically insoluble in water temperature 670-720 ⁰ C and with the addition of salt. That is why it is convenient to a temperature from 670 to 730 ⁰ C, respectively. 15 in the production of granulated, magnesium-containing
