Abstract

Patente de Invenção de "MéTODO PARA PRODUZIR UMA LIGA DE MAGNéSIO DE LIGA DE MAGNéSIO". Um método para produzir uma liga de magnésio de altta pureza é apresentado, no qual os componentes de liga são introduzidos no estado fundido ao magnésio fundido. De acordo com o processo da invenção, uma quantidade pré-determinada de magnésio primário é aquecida e fundida em um cadinho. Quantidades pré-determinadas de metais de liga desejados são selecionados e aquecidos até sua temperatura de fusão em um cadinho separado. Os metais de liga fundida são, então, introduzidos ao magnésio fundido misturando-se substancial e instantaneamente com o magnésio fundido em uma reação que eleva a temperatura do fundido. Foi descoberto que manganês elementar quando primeiramente misturado com outros metais da liga antes de sua adição ao magnésio fundido é, consistentemente, mais efetivo na redução do nível de impureza de ferro do fundido até um nível abaixo de 50 ppm. A introdução de uma liga fundida de manganês e um ou mais metais de terras raras no magnésio fundido, reduz a sedimentação do metal de terra rara para fora do fundido e aumenta a eficiência da liga para o metal de terra rara para mais de 80%. A eficiência do processo da invenção é aumentada substancialmente, o consumo de tempo e energia é diminuído, e a produção de escória de cloreto de magnésio e HC1 gasoso é evitada.Patent of Invention of "METHOD TO PRODUCE A MAGNESIUM ALLOY OF MAGNESIUM ALLOY". A method for producing a high purity magnesium alloy is presented, in which the alloy components are introduced in the molten state to the molten magnesium. According to the process of the invention, a predetermined amount of primary magnesium is heated and melted in a crucible. Predetermined amounts of desired alloy metals are selected and heated to their melting temperature in a separate crucible. The molten alloy metals are then introduced to the molten magnesium by substantially and instantly mixing with the molten magnesium in a reaction that raises the melt temperature. It has been found that elemental manganese when first mixed with other alloy metals before its addition to molten magnesium is consistently more effective in reducing the level of iron impurity in the melt to below 50 ppm. The introduction of a molten alloy of manganese and one or more rare earth metals in the molten magnesium, reduces the sedimentation of the rare earth metal out of the melt and increases the efficiency of the alloy for the rare earth metal to over 80%. The efficiency of the process of the invention is substantially increased, the consumption of time and energy is decreased, and the production of slag of magnesium chloride and HCl gas is avoided.
