Degassing of Aluminum Alloy Melts by High Shear Melt Conditioning Technology: An Overview

The search for more efficient methods degassing aluminum alloy melts has always been of great interest the metal industry because presence hydrogen and oxides in melts’ prior casting was detrimental to integrity properties final products. In this work, we present an overview progress key findings from research development innovative High Shear Melt Conditioning (HSMC) technology during Liquid Metal Engineering (LiME) Research Hub project. Compared conventional rotary degassing, novel technique capable working at higher rotor speeds efficiently break disperse naturally occurring oxide bifilms melt capture each supplied inert gas bubble into many tiny bubbles throughout whole melt. This resulted elimination need degas fluxes remove melt, reduction flow required reach same level removal rate, minimization regassing effect after processing. increased process efficiency allowed reduced processing costs and, time, improved quality, which fewer defects mechanical properties.
