Abstract (en)
[origin: EP2497585A1] Provided is a continuous casting method of molten metal in which a hollow cylindrical, conical or truncated cone type refractory-made structure having one or more side holes in the sidewall thereof is disposed in a tundish above a submerged entry nozzle with the central axis of the refractory-made structure aligned vertically to supply molten metal from the tundish to the submerged entry nozzle, wherein an angle ¸1 is formed between a virtual line extending radially from the center of a horizontal circular cross-section of the refractory-made structure and the central axis of the side hole; molten metal in the tundish is passed through the side holes, whereby a swirling flow is generated in the molten metal to be supplied into the submerged entry nozzle; and the flow rate Q of the molten metal, the total opening areas S of the side holes, the mean inner radius R of horizontal circular cross-section in the region having openings of side holes, and the angle ¸1, in combination, satisfy 0.015 m 2 /s‰¤ R×Q/S×Sin¸1‰¤ 0.100 m 2 /s. A swirling flow mechanism is provided in the tundish, whereby the flow of molten metal in the mold can be stabilized.
