Abstract
Particle settling and stratification in aluminium processing operations are of importance for cast house performance and product quality as they influence important factors such as furnace cleaning frequency, and design of launder troughs and inline equipment.
Analytical analyses of settling generally refer to Stokes’ law describing the motion of a solid sphere in a liquid but neglect the dominating factor of thermal convection. A new option to monitor particle concentrations at different melt depths based on LiMCA technology was utilized to study particle settling within AMAP, the Open Innovation Research Cluster for Non-Ferrous Metals at RWTH Aachen University.
This paper reports the initial results obtained with the new LiMCA method in trials in a laboratory crucible furnace. The results are analysed with respect to the influence of particle size on settling kinetics and stratification and are compared to the above mentioned theoretical calculations.
