| description | High-purity titanium (Ti) and its alloys are among the most promising materials for advanced turbine blades in aerospace engines. Electromagnetic cold crucible melting is a novel technique for producing contamination-free pure Ti ingots. To enhance the utilization efficiency of electromagnetic energy, an initial assessment of the electromagnetic energy utilization rate of the cold crucible was conducted. Subsequently, based on numerical simulation, the impact of electromagnetic energy on the uniformity of the electromagnetic field within the Ti melt was investigated, providing a theoretical basis for performance optimization. The results indicated that a cylindrical structure with a spherical bottom significantly improves the electromagnetic utilization and temperature uniformity of the crucible. Finally, using the optimized crucible, a measurement apparatus for the spectral emissivity of molten Ti was developed. By simulation and optimization of the optical path system and sample temperature field, high-precision spectral emissivity measurement of molten Ti was achieved. This study underscores the potential of optimized electromagnetic cold crucible technology in advancing the production and precise measurement of high-purity Ti, critical for aerospace applications. |
