Cold Simulation of momentum transfer of a metal droplet falling through slag systems possessing net-work structured fluids

Abstract

Most of the high temperature smelting/refining processes involve falling of metal droplets through the slag systems. The slag systems comprising oxides viz., Al2O3, SiO2, CaO, FeO, MgO, MnO etc., are essentially produced from the removal of ash and gangue from coke and/or ore during the metal extraction. At high temperatures these oxides form a network structured fluids. Momentum transfer phenomena of a falling sphere through these slag systems significantly influence the kinetics of the refining reactions occurring in the high temperature metallurgical reactors. It governs the metal quality including their productivity. The paper discusses cold simulation of the momentum transfer of a metal droplet falling through the slag systems possessing network structure. (C) 2010 Elsevier Ltd. All rights reserved.
