Abstract

본 발명은, 유체도입구멍(8)과 유체도입구멍(8)으로부터 흘러온 용융유체를 토출하고 안지름이 유체도입구멍(8)의 안지름보다 작은 유체토출구멍(10)으로 구성되는 복수개의 방사구멍(4)을 가진 방사용 노즐판(1)을 제공한다. 유체토출구멍(10)의 입구와 연결되는 각 방사구멍(4) 내면의 적어도 한부분은 유체토출구멍(10)입구의 형상선이 나타나지 않도록 유연한 3차원곡면으로 형성한다. 융용유체 체류의 원인이 되는 부분을 제거하고, 이것에 의해 매우 유연한 흐름을 실현하고 압력손실을 작게 한다.According to the present invention, a plurality of spinning holes (10) are formed of a fluid discharge hole (10) which discharges the molten fluid flowing from the fluid introduction hole (8) and the fluid introduction hole (8) and whose inner diameter is smaller than the inner diameter of the fluid introduction hole (8). There is provided a spinning nozzle plate 1 having 4). At least one portion of the inner surface of each of the radiation holes 4 connected to the inlet of the fluid discharge hole 10 is formed as a flexible three-dimensional curved surface so that the shape line of the inlet of the fluid discharge hole 10 does not appear. The part causing the molten fluid retention is removed, thereby realizing a very flexible flow and reducing the pressure loss.
