| 摘要 | Nozzle for guiding molten metal, including an inlet at an upstream first end, at least one outlet towards a downstream second end, and an inner surface between the inlet and the outlet defining a bore through the nozzle having a throat region adjacent the inlet. An annular channel is provided in the inner surface of the nozzle, and a fluid supply is arranged to introduce fluid into the bore via the annular channel or downstream thereof. The throat region has a convexly curved surface and the annular channel is located within or adjacent the convexly curved surface of the throat region. | ||

| 主权项 | 1. A nozzle for guiding molten metal comprising: an inlet at an upstream first end; at least one outlet towards a downstream second end; an inner surface between said inlet and said at least one outlet defining a bore through the nozzle; the bore having a throat region adjacent the inlet; an annular channel provided in the inner surface of the nozzle in direct communication with the bore; and a fluid supply means arranged to introduce fluid into the bore via the annular channel or downstream thereof; said throat region having a convexly curved surface and said annular channel being located within or adjacent the convexly curved surface of the throat region; whereby molten metal flowing into the throat region is thrown off the inner surface of the nozzle due to the presence of the annular channel. | ||
