Process and device for the atomization of at least one jet of a liquid, preferably molten metal

Abstract

Abstract 1. Process and device for the atomisation of at least one jet of a liquid, preferably molten metal. <??>2.1. Known methods and devices of the type concerned here have poor atomisation performance and consequently slow cooling of the atomised metal particles or the like. This leads to unfavourable grain formations. The process according to the invention and a corresponding device are intended to obviate these disadvantages. <??>2.2. As regards the process, it is proposed to atomise the molten metal particles or the like in a compressed gaseous medium, which offers a higher energy transfer for the ultrasound employed. It is furthermore proposed, as regards the device, to employ a plurality of ultrasonic oscillators (12). By superposition, these produce a (common) ultrasonic field (27) with a high energy density in the nodal region (29). This gives more intensive atomisation and an associated improvement in the quenching rate. <??>2.3. The method proposed and the corresponding device are particularly suitable for producing specific materials or objects composed of these materials. <IMAGE>
