Foundry Hydrogen Remover is well-known fact that however carefully aluminum alloys are melted, hydrogen does find a way into the metal during melting. The solubility of this undesired gas increases as the temperature of the molten metal rises. During casting, the solubility drops which results in a sudden release of gas in the form of small bubbles. Because of this solubility difference, the gas may or may not escape from the melt before solidification is completed, causing alloy which in turn creates pin holes or scattered gas porosity in the castings. PMC Degasser-3 is a blue colored tablet, specifically prepared under controlled conditions. It effectively and significantly reduces the hydrogen content in the molten metal at a very minimal level to give a high-quality casting.

How to Use:

• These instructions are given only for Degassing treatment.
• For other fluxing treatment, please refer to the corresponding PMC flux literature
• Preheat the plungers and furnace tools which are suitably coated to avoid iron pick up
• Plunge PMC Degasser-3 tablets, in the recommended quantity, below the surface of the melt. If it is desired, carry-out the degassing operation in two stages using half the recommended quantity in each stage. However, the second stage should be carried out when the bubbling of the first stage completely subsides
• Leave the metal in an undisturbed condition for at least 2-3 minutes under a suitable protective cover of PMC Cover Flux
• Rabble the flux layer into the melt to obtain a glowing red metal free dross
• Skim off the dross and check the metal temperature before pouring

Product Details:

PMC Cover Flux is an off-white, high grade exothermic drossing-off flux meant for crucible melting of ingots and clean scrap for sand and die casting. This flux is formulated to effectively control oxide formation and inclusion of non-metallic impurities, leaving a relatively metal-free dross. It minimizes the hydrogen pick-up and absorbs as well as collects metallic oxides formed during melting operation. This makes the poured metal free from oxide inclusions. During stirring/ rabbling of the flux into the surface of the melt, a glowing red, metal-free dross is generated.

How to Use:

• Preheat the crucible to a red hot condition and charge carefully
• When the charge has reached the pasty stage, sprinkle a part of the recommended PMC Cover Flux over the surface so that the flux completely covers the melt surface
• Add the balance quantity of charge and add further quantity of flux to keep the flux cover intact and complete
• Continue further melting until the crucible is fully charged
• After degassing/ grain-refining treatment, sprinkle a further quantity of PMC Cover Flux and allow to stand for a few minutes
• Adjust the temperature, if necessary
• Rabble the flux into the surface of the melt to produce a glowing red metal-free dross
• Skim of the dross, check the pouring temperature and cast immediately
