Special Issue Information

Dear Colleagues,

Electromagnetic metallurgy technology utilizes the force and thermal effects of electromagnetic fields to achieve energy transfer, fluid motion, and shape control in metallurgical processes, ultimately aiming to optimize metallurgical processes, enhance production efficiency, and improve product quality and performance. In recent years, with the increasing awareness of low-carbon and environmental protection, electromagnetic metallurgy technology has garnered growing attention and emphasis in the metallurgy and materials preparation fields due to its advantages such as high efficiency, environmental friendliness, and excellent controllability. It exhibits the following development trends: (1) Automation and process advancement in the field of steel metallurgy. (2) Continuous expansion of its applications in various areas, including the entire process of steel continuous casting, non-ferrous metal smelting and casting, and the preparation of non-metallic and new materials. (3) The emergence of new technologies such as suspension metallurgy, strong magnetic fields, and static magnetic fields. The metallurgical and materials preparation process involves the coupling of multiple physical fields, including energy transfer and conversion, momentum and mass transfer, and structural evolution. In electromagnetic metallurgy processes, the electromagnetic-fluid phenomena resulting from the coupling of electromagnetic fields, flow fields, and temperature fields are a key focus of research and attention. This topic focuses on the research progress and development trend of electromagnetic technologies used in the field of Metallurgy and Materials, aiming to provide a platform to seek the new functionality of Electromagnetic metallurgy technologies, broadening their application fields in the future.

Impurity elimination in tundishes is an essential metallurgical function in continuous casting. If inclusions in a tundish cannot be effectively removed, their presence will have a serious impact on the quality of the bloom. As a result, this research investigates the locations of inclusion particles in a six-strand induction-heating tundish in depth, combining the flow, temperature, and inclusion trajectories of molten steel under electromagnetic fields. The results show that a pinch effect occurred in the induction-heating tundish, and a rotating magnetic field formed in the channel, with a maximum value of 0.158 T. The electromagnetic force was directed toward the center of the axis, and its numerical distribution corresponds to the magnetic flux density distribution, with a maximum value of 2.11 × 105 N/m3. The inclusion particles’ movement speed accelerated as the molten steel’s temperature rose, and their distribution in the channel was identical to the rotating flow field distribution. When the steel’s temperature rose from 1750 K to 1850 K, the removal percentage of inclusion particles in the discharge chamber rose by 9.20%, the removal rate at the outlet decreased from 8.00% to 3.00%, and the adhesion percentage of inclusion particles in the channel decreased from 48.40% to 44.40%.

Carbon segregation is the major and classical internal defect in the continuous casting process of carbon steel. Based on the combined electromagnetic stirring equipment for new billet in a steel plant, China, the influence of combined electromagnetic stirring (M-EMS + F-EMS) on the carbon segregation of 300 mm × 340 mm special-shaped billet was studied via numerical simulation and on-site industrialization tests. The Lorentz force and carbon solute distribution were simulated under different EMS parameters. The formation mechanism of the carbon segregation of medium carbon steel with different combined electromagnetic stirring processes was analyzed. The results show that: (1) with the combined action of “solute flushing” effect and gravity, the carbon concentration in the loose side of the medium carbon steel casting billet is gradually lower than the fixed side, while the carbon concentration on the fixed side gradually accumulates more; and (2) under the action of combined electromagnetic stirring, the segregation index of casting billet could be controlled to remain between 0.96–1.05 and shows an increasing change in solidification from the skin to the center. When the current and frequency of M-EMS are 250 A and 2.0 Hz and the F-EMS are 180 A and 8.0 Hz, the carbon segregation defects in the special-shaped (300 mm × 340 mm) casting billet can be significantly improved.
