Electromagnetic Stirring (External Field)

During processing of metal alloys, in addition to conventional stirring (e.g., that produced by coils), an external electromagnetic field is applied to achieve stirring. The electromagnetic field interacts with the material, generating electromagnetic forces that drive charged particles, thereby stirring the entire melt. This stirring method allows more thorough mixing, resulting in more uniform alloy composition and improved quality/performance.

Technical Solution

A protective sleeve is placed over the induction coil. Inside the sleeve is a heating element, and inside the heating element is a crucible. The crucible is mounted on a directional solidification rod. The heating element is inductively heated and radiates heat to the crucible, melting the material inside. Activating the lower cylinder quickly lowers the crucible into the cooling bath for quenching.
