Introduction :

When Aluminium alloys are melted, hydrogen is absorbed. Gas porosity in Aluminium alloy casting is common phenomenon, which results in heavy rejection of finished products.


Description :

Degasser - 22 is a blue coloured tablet. It is an efficient Degasser. The main function of Degasser is to remove harmful gases, mainly hydrogen and hence to reduce hydrogen and porosity to a minimum.

Quality To Be Use :

150 grams per 100kg MELT.
Preheat Furnace OR Crucibles to red hot condition.
Charge in ingot and scrap.
As soon as the charge reaches a pasty from, sprinkle Cover Flux – 11 over its surface to form a cover.
Add remainder of charge and melt repaidly.
Do not permit metal temp. to exceed above 750° C. There Should be sufficient heat in the Crucible to keep the temp of the melt from falling and during this period the melt should be degassed with Degasser-22.
Hold tablet at the bottom of the melt duly coated with a bell type plunger. The bubbling action will cease after 4 minutes.
Remove the plunger from the melt and sprinkle a quantity of Refining flux 12H on the surface of the melt and rabble the flux layer into the melt to obtain a red glowing dross free from metal.
