ABSTRACT:

In this paper we reported the diminution pattern of hydrogen contents in molten aluminium alloys during casting on industrial scale, and estimated the efficiency of inline rotary degassing system. The degassing parameters were tried to set constant in nearly 150 heats, so that other factors which govern the degassing efficiency of inline unit could be in-sighted well. In this study we used Leco RHEN-602 hydrogen determinator based on the principle of hot extraction carrier gas method, for the measurement of dissolved hydrogen in molten metal and from these results efficiency of inline rotary degassing unit was calculated. The results obtained were cross checked by observing hydrogen porosity in final castings; it endorsed the values obtained through RHEN-602 analyzer. This study showed that hydrogen removal efficiency of the rotary degassing unit was nearly 40 % for various aluminum alloys.
