MOLTEN METAL FEED NOZZLE

摘要

A molten metal feed nozzle, wherein an extension body (11) having a lower portion immersed in a molten metal sump and projected toward a side dam (2) so that the area of a stagnated part on the free liquid level of a molten metal can be eliminated is formed at the end thereof. The extension body (11) is formed in such a shape that a quadrangular pyramid is fallen sideways, and converged toward a point (P1) near the side dam (2). Since the nozzle replaces the area of the stagnated part on the free liquid level of the molten metal with the extension body (11) continued to the end of the nozzle to suppress the generation of unnecessary solidified shell, the solidified shell generated on the outer peripheral surface of cooling rolls (1) and forming a strip does not hold the unnecessary solidified shell as foreign matter, and the breakage of the strip resulting from an increase in a clearance between the rolls can be avoided.
