Abstract
Fremgangsmåte for fremstilling av en magne- siumlegering med høy renhet, hvor de legerende komponenter fores i smeltet tilstand inn i smeltet magnesium. I henhold til fremgangsmåten ifølge oppfinnelsen oppvarmes en på forhånd bestemt mengde primært magnesium og smeltes i en digel. På forhånd bestemte mengder av ønskede legerende metaller velges ut og oppvarmes til smeltetemperaturen i en separat digel. De smel- tede legerende metaller føres så inn i det smel- tede magnesium for i hovedsak øyeblikkelig å legeres med det smeltede magnesium i en reaksjon som fører til at temperaturen i smelten stiger. Elementært mangan som først legeres med andre legerende metaller før tilsetning til det smel- tede magnesium blir funnet å være konsistent mer effektivt for reduksjon i jernforurensnings- nivået i smelten til et nivå under 50 ppm. Inn- føringen av en smeltet legering av mangan og ett eller flere sjeldne jordmetaller i det smeltede magnesium reduserer en avsetning av det sjeldne jordmetall fra smelten og øker den legerende effektivitet for det sjeldne jordmetall til mer enn 80%. Effektiviteten for fremgangsmåten ifølge oppfinnelsen økes i betraktelig grad, forbruket av tid og energi minskes og produk- sjonen av magnesiumklorid-slagg og gassformig HC1 unngås.A process for preparing a high purity magnesium alloy in which the alloying components are fed in molten state into molten magnesium. According to the process of the invention, a predetermined amount of primary magnesium is heated and melted in a crucible. Predefined amounts of desired alloying metals are selected and heated to the melting temperature in a separate crucible. The molten alloying metals are then introduced into the molten magnesium to be substantially immediately alloyed with the molten magnesium in a reaction which causes the temperature of the melt to rise. Elemental manganese that is first alloyed with other alloying metals prior to addition to the molten magnesium is found to be consistently more effective in reducing the iron pollution level in the melt to a level below 50 ppm. The introduction of a molten alloy of manganese and one or more rare earth metals into the molten magnesium reduces the deposition of the rare earth metal from the melt and increases the alloying efficiency of the rare earth metal to more than 80%. The efficiency of the process according to the invention is greatly increased, the consumption of time and energy is reduced and the production of magnesium chloride slag and gaseous HCl is avoided.
