Product Description

DGR Degasser With Grain Refiner

Product in Brief

Aluminium & its alloys are susceptible in absorbing gas even when the best-controlled melting processes are performed. There are many factors which cause absorption of Hydrogen gas like water vapour from atmosphere, damp scrap, clamp tools, prolonged holding of metals etc. During the process of casting these unwanted gases release suddenly in the form of bubbles, which are trapped in the metal, and finally the development of pinhole porosity in the cast product occur. It is therefore necessary to remove the unwanted gas from the melt prior to pouring.
