Title:
GRANULAR METAL PRODUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/042824
Kind Code:
A1
Abstract:
A granular metal production device with which it is possible to make molten metal into granular metal of a predetermined grain size or less even if the height is restricted. The molten metal in a first flow path (9) collides with a step (11) at the inlet of a second flow path (10) created by a difference in opening area, causing rapid speed fluctuations to occur, when molten metal flows from the upper first flow path (9) into the lower second flow path (10) in a discharge port (4) provided in the bottom (3a) of a container (3). As a result, a speed distribution of the flow speed occurs within the cross-section of the molten metal flowing down from the second flow path (10), and this speed distribution allows the molten metal that collides with the collision structure (5) and scatters to be reliably granulated.
