Degasser Tablet

DEGASER (DEGASSING + GRAIN REFINING)

Product Overview

DEGASER products are compacted tablets in different sizes to facilitatetreatment of various melt sizes . They are plunged into aluminium melts fordegassing.

PURPOSE:

Even under the best melting conditions, it is often impossible to prevent hydrogengas from entering the melt which finally gives rise to porosity in the cast products. Itis therefore necessary to remove as much of hydrogen from the melt as possible priorto pouring

DEGASER range of products remove the dissolved hydrogen by diffusionprocess. Degassing with these products is superior to flushing with chlorine gaswhich is associated with problems of space, equipment, corrosion, health hazards, etc.Some of the degassing products contain grain refining elements also and theseproducts function as combined degassing and grain refining agents.

 

Instructions for use :

Degasser Tablets should be added to the molten aluminium at the recommended treatment temperature. The tablet should be introduced carefully below the surface of the melt using a suitable plunging tool or treatment equipment to ensure proper contact with the molten metal. Allow sufficient reaction time for the tablet to release the active degassing components and remove dissolved hydrogen from the melt. After treatment, allow the resulting impurities and dross to rise to the surface and skim them off thoroughly before casting.
