摘要： A nozzle for continuous casting of a clean steel capable of eliminating the adhesion of Al2O3 inclusions to the wall surface of a nozzle inside hole and sufficiently developing the effect of a swing vane as a measure against the drift of molten steel flow flowing down in the nozzle inside hole in the continuous casting of molten steel. The nozzle is formed of a refractory manufactured by controlling a CaO/MgO weight percent and an apparent porosity, and the swing vane is installed in the inside hole in which an inner layer of 3 to 20 mm in thickness is formed as an annular refractory. Thus, the adhesion of Al2O3 inclusions to the wall surface of the inside hole and the swing vane can be effectively prevented and the drift of the molten steel can be effectively prevented over a long period. Since inert gas is jetted between the upper nozzle and the upper position of the swing vane, the mixing of Al2O3 inclusions into the molten steel can be suppressed by promoting the rise of the inclusions to stably perform the operation and provide excellent highly clean steel quality.

摘要： Provided is a molten metal discharge nozzle capable of suppressing turbulence in a molten metal stream passing through an inner bore thereof, with a simple structure. A cross-sectional shape of a wall surface of the inner bore, taken along an axis of the inner bore, comprises a part or an entirety of a curved line expressed by the following formula: log(r (z)) = (1 / n) × log((Hc + L) / (Hc + z)) + log(r (L)) (1), where: 6 ‰¥ n ‰¥ 1.5; L is a length of the nozzle; Hc is a calculative hydrostatic head; and r(z) is a radius of the inner bore at a position located a distance z downward from an upper end of the nozzle, wherein, in a graph where the distance z is plotted with respect to a horizontal axis (X-axis) thereof, and a pressure of molten metal at a center of the inner bore in horizontal cross-section at a position located the distance z is plotted with respect to a vertical axis (Y-axis) thereof, an approximation formula of a line on the graph is established without simultaneously including two or more coefficients having opposite signs, and wherein, on an assumption that the line is derived from an approximation formula based on a linear regression, an absolute value of a correlation coefficient of the line is 0.95 or more.
