The observation that, in a vacuum casting process casting high temperature alloy castings during solidification complex field for the organization will have some impact. Visible, if we can take advantage of the special nature of this case, the quality of high-temperature alloy castings can thus be improved. However, if control is not good, high temperature alloy castings can therefore have serious defects.

During solidification of superalloy vacuum casting, applying a rotating electromagnetic field of a certain strength, it found that the number and distribution of high-temperature alloy castings internal inclusions can be improved, thereby reducing dendrite segregation. But in this process, we must strictly control the start time good electromagnetic stirring, so as to ensure the stability of the surface of the liquid metal solidified shell, to avoid casting purity and uniformity adversely affected.
This way if you can master and use, it can be further improved cast superalloy vacuum casting quality to meet the high quality requirements of industrial development proposed for casting.
