Abstract

The invention relates to a refining flux for smelting of magnesium alloy, and in particular relates to a refining flux for smelting of WE43 magnesium alloy, and a preparation method and a usage method thereof. The refining flux is characterized by comprising the following raw materials, by weight: 60-62% of potassium chloride, 5-10% of calcium fluoride, 3-5% of yttrium chloride, 8-12% of calcium chloride and 18-20% of barium chloride. The invention has the advantages of easily available raw materials, effectively controlled smelting cost, good refining effect, significantly increased yields of Y and Nd elements, and further saving of rare earth resources; therefore, the invention has a breakthrough significance in the research of the field.

Description

technical field [0001] The invention relates to a refining flux for smelting magnesium alloys, in particular to a refining flux for smelting WE43 magnesium alloys and methods for preparing and using the same. Background technique [0002] Compared with ordinary magnesium alloys, rare earth magnesium alloys not only inherit the advantages of low density, high specific strength, high specific stiffness, good shock absorption, easy processing, and easy recycling, but also have better low-temperature and high-temperature mechanical properties. The corrosion resistance and heat resistance are also greatly improved compared with ordinary magnesium alloys, which effectively expands the application fields of magnesium alloys. [0003] WE43 magnesium alloy has excellent comprehensive performance and long-term stability of performance. The tensile strength can reach 190Mpa at 573K. It is suitable for use below 523K. Compared with other magnesium alloys with the same performance, the c...
