| Popis: |
Degassing operations are common methods to remove inclusions and oxides from the melt. In many occasions, fluxes are used through the melt in order to increase efficiency of oxide removal. In this work, a dirty melt was prepared by means of adding 50 wt% swarf to primary A356 alloy. Fluxes with various ratios of NaCl–KCl and MgCl2–KCl salts were prepared. Different weight ratio of Na3AlF6 and AlF3 was added. Melt cleanliness was measured by means of change in bifilm index (ΔBI) before and after degassing. It was concluded that most of the fluxes had cleaning efficiency below 40% while MgCl2 based fluxes had over 70% cleaning effect. |
