Eiga coil for partial melting of an electrode
The granted patent US12048081B2 introduces an innovative Electromagnetic Induction Gas Atomization (EIGA) coil designed for melting electrodes. The coil features multiple coaxially arranged windings that are axially spaced and shaped as rings with gaps ranging from 0.5 mm to 30 mm. Each winding is connected to adjacent ones via a connecting portion, and the design allows for variations in inner diameters among the windings, with the largest diameter ranging from 40 mm to 300 mm and the smallest from 10 mm to 100 mm. The coil can also exhibit different cross-sectional geometries and is constructed from ceramic-free copper, produced through an additive manufacturing process.
Additionally, the patent outlines an apparatus for executing the EIGA method, which includes the EIGA coil, a displaceable electrode that extends partially into the coil, and a nozzle for atomizing the melted electrode material. The method involves displacing the electrode relative to the coil while applying alternating current to generate Lorentz forces that facilitate the melting process. This technology aims to produce high-purity metal powder efficiently, leveraging the unique design and operational capabilities of the EIGA coil and associated apparatus.
