In-Situ Detection of Inclusions in Liquid Steel
Publié en 2008
A numerical multiphase flow model is proposed to predict the behavior and motion of entrained inclusions in liquid steel, as they enter the orifice of a LiMCA (Liquid Metal Cleanliness Analyzer) sensor for assuring steel quality. The method of measurement is based on the electric sensing zone (ESZ) technique.
The liquid metal flow field within the ESZ is obtained by solving the Navier-Stokes equations coupled to a self-induced electromagnetic field. The trajectories of these entrained inclusions have been modeled using a momentum. This COMSOL model allows for parametric studies with varying physical properties and simulation of different kinds of liquid metals.
