Abstract

FIELD: magnesium alloy production. SUBSTANCE: predetermined quantity of crude magnesium is heated and melted in crucible. Simultaneously, in second crucible, predetermined quantities of selected purposive alloy-forming metals are heated up to their melting temperatures. Molten alloy-forming metals are added to molten magnesium. Almost immediately alloy is formed with molten magnesium, accompanied by reaction increasing melt temperature. It was established that elemental manganese, if it is first introduced into alloy with other alloy-forming metals, before adding them to molten magnesium, effectively and stably reduces iron impurity content down to level less than 50 ppm. Addition of molten alloy of manganese with one or more rare-earth metals to molten magnesium prevents precipitation of rare-earth metals from melt and increases alloy-forming efficiency for rare- earth metal up to level exceeding 80%. Method is highly effective, takes less time and energy, rules out formation of sodium chloride slag and gaseous hydrogen chloride. EFFECT: effective method for producing high-purity magnesium alloy.

Предложен способ получения магниевого сплава высокой чистоты, в котором сплавообразующие компоненты в расплавленном состоянии добавляют к расплавленному магнию. Согласно способу изобретения заданное количество первичного магния нагревают и плавят в тигле. Во втором тигле заданные количества отобранных целевых сплавообразующих металлов нагревают до их температур плавления. Расплавленные сплавообразующие металлы добавляют к расплавленному магнию, при этом почти немедленно образуется сплав с расплавленным магнием в реакции, повышающей температуру расплава. Обнаружено, что элементный марганец, если его вначале ввести в сплав с другими сплавообразующими металлами перед их добавлением к расплавленному магнию, устойчиво более эффективен в снижении содержания примесного железа до уровня в менее, чем 50 ч/млн. Добавление к расплавленному магнию расплавленного сплава марганца и одного или нескольких редкоземельных металлов препятствуют осаждению редкоземельных металлов из расплава и повышает сплавообразующую эффективность для редкоземельного металла до уровня, превышающего 80%. Эффективность способа изобретения существенно повышена, расход времени и энергии уменьшен, образование шлака хлорида натрия и газообразного HCI исключено.A method for producing high-purity magnesium alloy is proposed, in which alloy-forming components in the molten state are added to molten magnesium. According to the method of the invention, a predetermined amount of primary magnesium is heated and melted in a crucible. In a second crucible, predetermined amounts of selected target alloy-forming metals are heated to their melting points. The molten alloy forming metals are added to the molten magnesium, and an alloy with molten magnesium is formed almost immediately in a reaction that raises the temperature of the melt. It was found that elemental manganese, if it is first introduced into an alloy with other alloy-forming metals before being added to molten magnesium, is stably more effective in reducing the content of impurity iron to less than 50 ppm. The addition of molten manganese alloy and one or more rare earth metals to the molten magnesium interferes with the deposition of rare earth metals from the melt and increases the alloying efficiency for the rare earth metal to a level exceeding 80%. The effectiveness of the method of the invention is significantly increased, the time and energy consumption is reduced, the formation of slag of sodium chloride and gaseous HCI is excluded.
