Description
Non-metallic inclusions severely affect ultra-low carbon steel properties and continuous casting efficiency. This study applies pulsed electric current (PEC) to regulate inclusions by leveraging the positive charge of Al2O3 in molten steel. Industrial practice confirms PEC’s feasibility: it reduces nozzle inner wall adhering layer thickness, enables 7-heat continuous casting (≥1000 tons with single nozzle), and eliminates >20 μm inclusions. The proportion of ≤5 μm inclusions increases, mold-level stability improves. Overall, PEC regulation improves steel cleanliness, inclusion size distribution, mold-level stability, and reduces defects, providing technical support for high-quality ultra-low carbon steel production.
