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
