Continuous Casting of Steel Billet with

Electromagnetic continuous casting (EMC) technology has propelled advancements in metal processing, particularly for aluminum and steel. This study analyzes the efficacy of EMC in enhancing not only the surface quality but also the inner integrity of aluminum strands during the casting process. Through extensive research conducted since the 1980s, two approaches have emerged: using a cold crucible mold operated at high frequency and a conventional mold with lower frequency. The findings reveal challenges and advantages associated with each method, particularly regarding mold design and the stability of molten metal levels. Additionally, key process parameters—including the coil position relative to the molten pool and the type of mold flux—are critical for optimizing strand quality. The research suggests that although high-frequency systems present design complexities, there remains significant potential for EMC technology in steel casting, paving the way for defect-free direct rolling processes. Consequently, this investigation provides valuable insights into improving casting quality through electromagnetic methods, underscoring the technology's promise for future applications in manufacturing sectors.
