Intelligent Sensors for Atomization Processing of Molten Metals and Alloys

Abstract

We briefly introduce the principles of atomization processing of molten metals and alloys, discuss potentially applicable instrumentation, and propose opportunities for developing intelligent sensors for monitoring and control of the process. Particle size and velocity are considered the two most important variables to monitor and control the atomization process. Several on- line sensors suitable for atomization of molten metals and alloys are compared: laser light scattering methods using small angle scattering analysis, moderate angle scattering analysis, and doppler analysis; electrical methods using surface ionization and triboelectric charging, and image analysis. Keywords: Molten, Atomization, Metals, Alloys, Sensors, Laser light, Scattering analysis, Doppler analysis, Ionization, Triboelectric charging, Isokinetic sampling probe.
