Product Description

Pure Iron Flux: Essential Auxiliary for Metallurgical Smelting

Product Description

Pure Iron Flux is a high-performance functional auxiliary widely used in metal smelting and casting processes. With iron content ≥99% and ultra-low impurities (S, P, Si ≤0.1%), it effectively optimizes melting efficiency, enhances metal purity, and reduces casting defects, making it an indispensable material in steelmaking, non-ferrous metal refining, and precious metal purification.

Core Features

1. High Purity & Low Impurities

Iron content reaches over 99%, with strict control of harmful impurities. It avoids secondary pollution to molten metals, especially suitable for high-purity requirements in precious metal (gold, silver, platinum) refining.

1. Excellent Fluxing Performance

Reduces the melting point of metal raw materials (working temperature: 800-1500ºC) and improves molten metal fluidity, cutting energy consumption by 5%-10% and boosting production efficiency.

1. Efficient Deoxidation & Impurity Removal

Reacts with oxides (e.g., FeO, MnO) in molten metal to form easy-to-separate slag, while consuming oxygen to lower the oxygen content of finished metals. This minimizes casting defects like pores and cracks.

1. Versatile Forms

Mainly supplied as powder (100-325 mesh), with granular form available on demand. The powder form maximizes contact area with molten metal, enhancing fluxing and impurity-removing effects.

Application Fields

• Steelmaking Industry

Used in converter/electric furnace steelmaking to reduce melting temperature of iron ore/scrap steel, promote slag formation, and adsorb S/P impurities, improving molten steel purity and ensuring mechanical properties of steel products.

• Non-Ferrous Metal Refining

Ideal for smelting copper, aluminum, nickel, etc. It reduces the impact of metal oxides on finished products, supporting high-precision copper/aluminum alloy production for electronics and aerospace industries.

• Precious Metal Purification

Assists in removing base metals (iron, copper) from gold, silver, and platinum-group metals, ensuring precious metal purity reaches over 99.99% without introducing new contaminants.

• Metal Casting

Optimizes molten iron fluidity in cast iron/steel casting, reduces internal pores and shrinkage of castings, and increases casting density and yield.

Usage Notes

1. Adjust the addition amount (0.5%-2% of total raw materials) according to the type of molten metal, purity requirements, and smelting equipment (electric furnace, intermediate frequency furnace) to avoid abnormal iron content.

1. Powdered products are moisture-absorbent; store in a sealed, dry environment. Dry at 100-150ºC before use to prevent bubbles caused by moisture entering molten metal.

1. Wear protective gear (high-temperature gloves, goggles) during operation to avoid burns from splashing high-temperature powder.
