Research on Eddy Electromagnetic Oscillator for Purification of Molten Aluminum

With the rapid development of modern industry, metal materials require more and more cleanliness and refinement of solidified tissue. Blade casting usually uses molten aluminium as the material, and faces problems such as coarse solidification tissue when forming. In order to solve the problem of uneven electromagnetic distribution during purification of traditional disc electromagnetic oscillator, this paper designs a fan-shaped structure eddy current induction electromagnetic oscillator. Firstly, the theoretical basis of the electromagnetic oscillator design is analysed. Secondly, the electromagnetic characteristics are simulated by using Ansys Maxwell electromagnetic simulation software, and the internal magnetic field characteristics are analysed in depth. Finally, the reasonableness of the design is verified by analysing the magnetic field distribution at the position of the blade warps.
