General Purpose Liquid Soldering Flux
Weldcote Metals 842 Oak Grove Rd. Kings Mountain, NC 28086 704-739-4115 www.weldcotemetals.com WELDCOTE GENERAL PURPOSE LIQUID SOLDERING FLUX General Purpose Liquid Soldering Flux Formulated for soldering Stainless Steel and High-Chrome Alloys. Excellent across a broad range of base metals, solders, and temperatures. Exhibits excellent capillary action. DESCRIPTION Weldcote Liquid Soldering Flux is a water-based, general purpose, inorganic-acid flux formulated for soldering stainless steel and other industrial metals. The flux contains Zinc Chloride, Ammonium Chloride, and Hydrochloric Acid, that make this flux active at room temperature where it begins to clean metals and remove oxides. The flux exerts a strong scavenging action to remove oxide coatings and other impurities from the metal surface to produce strong joints. Pre-cleaning is not necessary under most conditions. APPLICATIONS Weldcote Liquid Soldering Flux is excellent for use on Stainless Steel, Monel, High-Chrome Alloys, Inconel, Nickel, Copper, Brass, Ferrous Alloys and many more metals. It is not recommended for Aluminum and Magnesium. DIRECTIONS Weldcote Liquid Soldering Flux may be applied with a brush, swab or by dipping. The flux exhibits the best activity between 93°C/200°F and 315°C/600°F. Post-solder residues are water-soluble and hot water rinses (140°F or higher) may be adequate for most applications. The following steps are recommended for optimum soldering results: • Remove any oil, grease, or other contaminants from the surface to be soldered. • Apply flux to joint by dipping, spraying, dragging, swabbing or brushing to area being soldered. • Preheat or air-dry area to be soldered after flux has been applied to activate the flux and yield optimum soldering characteristics and reduce or eliminate spattering. -

Blast Furnace Stove Dome and Hot Blast Main
BLAST FURNACE STOVE DOME AND HOT BLAST MAIN The quality and composition of iron produced in the blast furnace is directly related to the hearth temperature. This, in turn, is dependent on the temperature of the hot blast delivered from the blast furnace stoves. To maximise the efficiency of the stoves, they are operated at high temperatures, close to the safe working limit of the refractories. This makes it critical to carefully monitor the stove temperature. BLAST FURNACES AND STOVES Blast furnaces heat iron ore to a period of accumulation, flow is produce the iron required as a reversed, and the hot stove is used raw material for steel-making.

SHEETMETAL FABRICATION TECHNICAL TIPS for SOLDERING Flux
SHEETMETAL FABRICATION TECHNICAL TIPS FOR SOLDERING Flux In metallurgy, a flux (derived from Latin fluxus meaning “flow”), is a chemical cleaning agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time. They are used in both metallurgy and metal joining. In high-temperature metal joining processes (welding, brazing and soldering), the primary purpose of flux is to prevent oxidation of the base and filler materials. Tin-lead solder (e.g.) attaches very well to copper, but poorly to the various oxides of copper, which form quickly at soldering temperatures. The role of a flux in joining processes is typically dual: 1. As cleaning agents, fluxes facilitate soldering by removing oxidation from the metals to be joined by dissolving the oxides on the metal surface, which facilitates wetting by molten solder. The flux also acts as an oxygen barrier by coating the hot surface, preventing further oxidation during the soldering process. 2. Additionally, flux allows solder to flow easily on the working piece rather than forming beads as it would otherwise. In some applications molten flux also serves as a heat transfer medium, facilitating heating of the joint by the soldering tool or molten solder. FLUX TYPES There are two types of fluxes used for soft soldering. These are organic (rosin based) fluxes or inorganic fluxes, usually based on halogenides and/or acids. Common fluxes are: ammonium chloride or rosin for soldering tin; hydrochloric acid and zinc chloride for soldering galvanized iron (and other zinc surfaces); and borax for brazing or braze-welding ferrous metals. -
Circuitworks® Tacky Flux
® CircuitWorks Tacky Flux: Use and Working Conditions By Milton Davis ® ITW Chemtronics 8125 Cobb Center Drive Kennesaw, GA 30152 770-424-4888 Tacky fluxes are commonly used in the electronics assembly industry for a variety of applications. These fluxes generally have honey-like consistency and can be used for ball attach applications, BGA re-balling and hand soldering applications. CircuitWorks® No-Clean Tacky Flux, part number CW8500, is a mildly activated rosin (RMA) no-clean tacky flux. Its formulation includes a unique rosin/resin blend coupled with a proprietary blend of activators and stabilizers, providing significantly increased shelf life and long-term product stability. This results in a post solder residue that is stable and can be left on a board without cleaning. Performance Characteristics CircuitWorks® No-Clean Tacky Flux offers a combination of a stable platform with robust activity. In this regard CircuitWorks® No-Clean Tacky Flux is ideally positioned between the more traditional RMA paste fluxes and the synthetic low residue-tacky fluxes. Typical RMA fluxes have strong activity but lack stability and consistency, whereas synthetic low-residue tacky fluxes are stable in their characteristics, but only sufficiently active for a limited range of soldering parameters. CircuitWorks® No-Clean Tacky Flux can be used in a wide range of soldering applications with predictable results. CircuitWorks® No-Clean Tacky Flux can be used for the following applications: BGA ball attachment and detachment; repair and rework of printed circuit board (PCB) components; and soldering of specialty components that cannot be attached in standard SMT reflow of PTH wave solder applications. -

The investigation of Oxide Inclusions removal in aluminium scrap casting process with sodium based fluxes has been carried out. The purpose of this research is to investigate the effect of Na2SO4 and NaCl based fluxes addition onto the fluidity and microstructure of aluminium product. The alloy which is used in this investigation is Al-Si which mixed with metal scrap using gravity casting method. The variation of melting temperature in this investigation are 700oC, 740oC, and 780oC. In this research, material characterization was determined using DSC, EDAX, XRD, and fluidity test. The results show that the number of oxide inclusions decrease as the addition of 0,2% wt. flux, and completly removed after the addition of 0,4% wt. flux. The highest fluidity and tensile strength was obtained after the addition of 0,4% wt. flux. at 7400C.. 1 Introduction Chemical components that are used in a flux depends on the objective of casting process (alkali removal, Aluminium alloys is widely applied in many industrial cleanliness, dross separation) [15]. In this paper flux product, such as transportation, packaging, construction, based Na2SO4 and NaCl was used to reduce the or houseware product due to its excellent properties, percentage of oxide inclusions inside the molten such as light weight, high corrosion resistance, high aluminium by binding the inclusions into the melt castability, and good conductor [1]-[4]. -
