Abstract
Viene descritto un metodo per preparare una lega di magnesio di elevata purezza, in cui i componenti della lega vengono introdotti allo stato fuso nel magnesio fuso. In accordo con il procedimento dell'invenzione, una quantità predeterminata di magnesio primario viene riscaldata e fusa in un crogiolo. Si scelgono quantità predeterminate di metalli desiderati per la lega e li si riscaldano in un crogiolo separato alla loro temperatura di fusione. I metalli fusi della lega vengono poi introdotti nel magnesio fuso in modo da legarli sostanzialmente in modo istantaneo con il magnesio fuso in una reazione che fa aumentare la temperatura della massa fusa. Quando legato per primo con altri metalli della lega prima della sua aggiunta al magnesio fuso, si è trovato che il manganese elementare è sostanzialmente più in grado di ridurre la quantità delle impurezze di ferro della massa fusa ad un livello inferiore a 50 ppm. L'introduzione di una lega fusa di manganese e di uno o più metalli delle terre rare nel magnesio fuso riduce un deposito del metallo delle terre rare e più dell'80%. L'efficienza del procedimento dell'invenzione è sostanzialmente aumentata, il consumo di tempo ed energia viene diminuito e si evita la produzione di scorie di cloruro di magnesio e di HCl gassoso.A method is described for preparing a high purity magnesium alloy, wherein the alloy components are introduced into the molten state in the molten magnesium. According to the process of the invention, a predetermined amount of primary magnesium is heated and melted in a crucible. Pre-determined quantities of metals desired for the alloy are selected and heated in a separate crucible at their melting temperature. The molten metals of the alloy are then introduced into the molten magnesium so as to bind them substantially instantaneously with the molten magnesium in a reaction which increases the temperature of the molten mass. When first bonded with other alloy metals prior to its addition to molten magnesium, elemental manganese has been found to be substantially more capable of reducing the amount of iron impurities of the melt to a level below 50 ppm. The introduction of a molten manganese alloy and one or more rare earth metals in the molten magnesium reduces a deposit of the rare earth metal and more than 80%. The efficiency of the process of the invention is substantially increased, the consumption of time and energy is decreased and the production of magnesium chloride and gaseous HCl slag is avoided.
