Product Description
Cover Flux SP-II (Modifier)
Aluminum &, 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 & 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-II (Blue)
This is a modifying typeof flux for Aluminum-Silicon alloys at low melting temperatures. The charge is melted under COVER FLUX SP-I & after required temperature is attained, degassing has to be performed with DEGASSER-SP-I. Rabble the surface of the melt & skim off the dross cleanly. Now sprinkle COVER FLUX SP-II about 3% by weight of metal over the cleaned surface. As soon as the flux layer liquefies, work well into the melt for 3-4 minutes by using tools. Finally skim off the metal free dross and. pour the metal without delay.
Packing: 50 packets of 1 kg. Packed in 50 kgs. Double Polylined Hessian sacks, which is solid enough to withstand shakes and jolts of transportation.
Purpose and AdvantagesCover Flux SP-II (Modifier) prevents oxidation and significantly reduces metal losses during aluminium alloy melting and casting operations. By forming an efficient cover, it ensures a cleaner melt with minimal dross, contributing to higher yields and improved metal quality.
Usage and ApplicationThis modifier is ideally used in aluminium foundries for both covering and modifying molten metal. It is compatible with a wide range of aluminium alloys, making it versatile for various non-ferrous metal processes. The products granulated form enables easy distribution and uniform performance during casting.
Storage and HandlingFor optimum performance and safety, store Cover Flux SP-II in a cool, dry area, tightly sealed in its original packaging. Always use gloves and goggles during handling to prevent direct contact. Its stable and non-poisonous nature ensures it remains safe under standard foundry conditions.
FAQs of Cover Flux SP-II (Modifier):
Q: How should Cover Flux SP-II (Modifier) be used in aluminium foundry processes?
A: Cover Flux SP-II should be sprinkled evenly over the molten aluminium or alloy during the melting or holding stages. This ensures optimal coverage, preventing oxidation and reducing metal losses for improved casting quality.
Q: What are the main benefits of using Cover Flux SP-II (Modifier)?
A: The primary benefits include minimizing oxidation, reducing metal loss, and improving the cleanliness of molten metal. Its high thermal stability and uniform granules ensure consistent performance and maximize recovery during aluminium casting.
Q: When is the best time to apply Cover Flux SP-II during the casting process?
A: It is most effective when applied after the metal has fully melted but before further refining or alloying. This timing allows the flux to efficiently cover the molten metal, protecting it from atmospheric gases.
Q: Where should Cover Flux SP-II (Modifier) be stored for longevity?
A: Store the product in a cool, dry place in tightly closed containers or the original packaging. Proper storage conditions help maintain its effectiveness and 12-month shelf life.
Q: What handling precautions are recommended with Cover Flux SP-II?
A: Operators should wear gloves and goggles to avoid skin or eye contact. Although non-poisonous and odourless, using personal protective equipment ensures safe handling.
Q: What distinguishes Cover Flux SP-II from other flux modifiers?
A: Cover Flux SP-II offers high purity, excellent compatibility with all aluminium alloys, uniform particle size as per specifications, and industry-standard performance, making it a reliable choice for foundries.
