Patent ID: 11400513

Abstract:
A continuous casting facility used for thin slab casting has a mold for casting molten steel, an immersion nozzle that supplies the molten steel into the mold, and an electromagnetic stirring device capable of providing a swirl flow at a molten steel surface in the mold, and a thickness DCu (mm) of a copper plate of a long side wall, a thickness T (mm) of a steel piece, a frequency f (Hz) of the electromagnetic stirring device, electric conductivity σ (S/m) of the molten steel, and electric conductivity σCu (S/m) of the copper plate of the long side wall are adjusted to satisfy the following formulae (1)-a and (1)-b: DCu<√(2/σCuωμ)  (1)-a√(1/2σωμ)<T  (1)-b,
