摘要：
The relationship between electromagnetic frequency and microstructures of continuous casting aluminum alloys was studied. 7075 aluminum alloy ingot of 100 mm in diameter was produced by the electromagnetic continuous casting process, and the microstructure of as-cast ingot was examined by scanning electron microscopy (SEM) equipped with energy dispersive spectrometer (EDS). The results showed that the electromagnetic frequency greatly influenced the segregation and microstructures of as-cast ingot, and the product quality could be guaranteed by the application of a proper frequency. It is shown that the electromagnetic frequency plays a significant role in the solute redistribution, are the low electromagnetic electromagnetic frequency is more efficient for promoting the solution of alloying elements.
