SPHERICAL BODY PRODUCTION DEVICE, AND METHOD FOR PRODUCING SPHERICAL BODY

摘要

PROBLEM TO BE SOLVED: To produce a spherical body with high weight and shape precision by dividing a melt with uniform weight.;SOLUTION: Disclosed is a spherical body production device where the melt is dropped to be changed into the spherical body, and comprises: a holding vessel holding the me a flow passage connected with the holding vessel and flowing out the me and a vibration device connected to the flow passage in such a manner that the vibrating direction is made parallel to the dropping direction of the melt, wherein provided that the area of the flow passage in the cross-section vertical to the flowing out direction of the melt is defined as a flow passage cross-sectional area, the flow passage is slidably connected to two or more flow passages having different flow passage cross-sectional areas.;COPYRIGHT: (C)2009,JPO&INPIT
