摘要： PROBLEM TO BE SOLVED: To provide an immersion tube for a molten metal refining facility.
SOLUTION: In this immersion tube for the molten metal refining facility, a monolithic refractory 2 is arranged on the outer periphery of a core metal 4 having a cylindrical shape and a regular-shaped refractory 3 is arranged in the inner periphery of the core metal 4. Then, the core metal 4 in the range of ≥100 mm at the lower part from the lower end of the regular-shaped refractory 3 arranged in the inner periphery of the core metal 4, is constituted so that the product X of a yield stress σ
y of the core metal 4 by thickness d of the core metal 4 satisfies (2) and (3) formulas. X
