Abstract
PURPOSE: To obtain a hollow pipe of a clean inside surface without allowing a solidified shell to contact a water cooled mold by holding the molten metal building up from an inlet in the outside shape of the hollow pipe in a high frequency current magnetic field, at the time of continuously pulling up the molten metal.
CONSTITUTION: The molten metal in a ladle 4 is poured into a tundish 1. The molten metal 8 building up in the upper part of an inlet 7 in accordance with the rise in the level of the poured molten metal 8 is maintained in the shape of a hollow pipe by the high frequency current magnetic field of a coil 6, and is cooled by the radiation without contacting a water cooled mold 2. Next, the solidified shell (a) formed by this cooling is pulled up, and is cut to a suitable length by a cutter 15.
