Cover flux Chemical

Product Description

We are greatly admired by our clients for manufacturing and exporting Cover Flux Chemical. It is a powdery mixture of chloride and fluoride salts which is used in foundries. This chemical is required to reduce the oxidation and minimizing the penetration of atmospheric hydrogen during melting. Cover Flux Chemical works by absorbing the non-metallic impurities in the melt resulting in clean walls of the furnace. It is applied to the melt surface and then stirred into melt.

Cover flux Chemical

Product in Brief

Aluminum and its alloys form a film of oxides during melting in open atmosphere. The density of this oxide film is just the same as of Aluminum and its alloys. Hence they are not readily separable and remain suspended in the melt which results in unsound casting and loss of precious metal.Thus prior to the casting of the metal, the removal of these suspended oxides from the melt is very much essential.

Cover fluxes when added to the melt, they form a protective cover over the melt and they curtail oxidation losses and minimize the hydrogen and carbon pickup. They also help in removing dirt and nonmetal ices and on skimming produce dross, low in metal content. There are various grades of Cover Fluxes, which are meant for different purposes.

COVER FLUX SP-IV (Blue) 

This Flux is highly Exothermic in nature. This flux is more suitable for Crucible Furnace and moreover for processing of dross. It gives best of Aluminium metal recovery from the dross. The application rate of this flux is 1%.

Packing

50 packets of 1 kg. approx. packed in 50 kgs. Double Polylined HDPE sack, which is solid enough to withstand shakes and jolts of transportation.

 

Effective Protection for Molten Aluminum

Cover Flux Chemical plays a vital role in shielding molten aluminum and its alloys from oxidation and atmospheric contamination during both melting and holding phases. This enhances the quality of the finished casting by minimizing impurities, ensuring smoother processing and improved end results.


Premium Composition for Optimal Performance

Formulated with high-purity sodium chloride, potassium chloride, cryolite, fluorspar, and other salts, this flux is tailored for solubility in molten metals while remaining insoluble in water. Its custom composition allows for flexibility to meet various manufacturing requirements, and its powdered form ensures easy application.


Applications in Aluminum Foundry Operations

Cover Flux Chemical is widely used by industrial foundries and casting facilities involved in aluminum processing. By forming a protective layer on the molten surface, it assists manufacturers, exporters, distributors, and suppliers in delivering high-integrity metallic products that comply with strict quality standards.
