Production of Metal Filament by In-Rotating-Water Spinning Method

Abstract

A new method is proposed, which can directly produce continuous filament with round cross-section from molten metal. In this method molten metal jet is ejected into the water layer formed on the inner surface of a rotating drum. Production examples of lead and Pd-alloy filaments are presented. In addition, the relation between the continuity, surface appearance and cross-section of lead filament and spinning conditions, such as drum speed, jet speed, incidence angle of jet into the water layer and water thickness, is discussed. This method may be applicable to the production of amorphous metal filaments with round cross-section.
