Title

Study of Relationship Between Atmospheric Humidity and Gas Porosity on Aluminium Alloys Casting

Abstract

Hydrogen gas naturally diffuses into liquid Aluminium. As the Aluminium solidifies, dissolve hydrogen will come out of solution and make bubbles, which appear as gas pits in casting. The quantity of bubbles is mainly determined by the amount of dissolved hydrogen in the melt at the casting. These gas pits have negative effect on the mechanical properties of the metal cast. Therefore, to remove these gas pits from cast we perform degassing process before casting. Degassing of molten Aluminium alloys is a foundry operation aimed to remove Hydrogen gas dissolved in the metal. Generally, in industries, rotary degassing method is used for degassing. In the rotary degassing method, an inert or chemically inactive gas such as Argon, Nitrogen, or mixed gas, is purged in molten metal to remove dissolve hydrogen gas. Atmospheric humidity also has great effect on degassing process, which needs to be standardized. In Al metal casting industry, the main reason for porosity is evolution of dissolve hydrogen gas during solidification of molten metal. Moisture in the atmosphere is the most prominent reason for the hydrogen generation in molten metal. Therefore, the atmospheric moisture (humidity) is an important parameter in the metal casting processes. In this study, I measure atmospheric humidity periodically in the metal foundry to monitor the moisture content. Average humidity content which includes relative humidity and absolute humidity in the atmosphere of metal foundry was collected for seven months regularly. These results indicate that humidity content is highest in the month of September, whereas lowest in the month of January. Here in present study we have tried to correlate the relationship between atmospheric humidity and porosity in cast metal after degassing.
