Vanadium Remover SY-CVJ1

SY-CVJ1

FEATURE DESCRIPTION:

Vanadium Remover SY-CVJ1 is an aluminum-based functional reagent. Leveraging aluminum's reducibility, it undergoes chemical reactions with vanadium elements in molten aluminum, converting vanadium impurities into precipitates or easily separable compounds to achieve molten aluminum purification. Its core principle involves utilizing aluminum as a reducing flux to preferentially form high-melting-point or insoluble products with vanadium. These products are then removed through processes such as solidification and dross skimming, thereby reducing vanadium content in aluminum products and enhancing purity.

Main Advantages

High-Efficiency Vanadium Removal:Aluminum’s strong reducibility targets vanadium in molten aluminum, converting it into precipitates with high removal efficiency to significantly lower vanadium levels.

Simple Process: Workflow involves mixing-smelting, solidification purification, and dross skimming. Easy to operate with no complex equipment needed, suitable for industrial continuous production.

Low Cost: Aluminum-based raw materials are readily available with low addition ratios, reducing overall production costs.

Environmental Friendliness: Reaction produces no toxic by-products, minimizing environmental impact and aligning with green smelting practices. It also avoids introducing new harmful impurities, ensuring product purity.

Strong Applicability: Suits diverse molten aluminum compositions and production scenarios, ideal for high-end aluminum processing fields sensitive to vanadium content, supporting downstream intensive processing needs.

Usage Method

Under an inert gas or nitrogen Temperature, heat the molten aluminum to be purified to 720℃-760℃. Depending on the vanadium content, the vanadium remover can be injected in batches; a second injection may be performed after testing results. After each injection of vanadium remover into the molten aluminum using a powder injection tank, skim the dross immediately after injection, , then hold the temperature for 15-25 minutes to allow the vanadium remover to fully react with vanadium in the molten aluminum.

Subsequently,conduct dross skimming again and let it stand for 30-40 minutes to allow the infusible reaction products to precipitate, thereby removing vanadium from the molten aluminum. When the vanadium content is below 100 ppm, the dosage of Vanadium remover should be increased as appropriate. The lower the Vanadium content, the greater the treatment difficulty, hence the dosage should be increased accordingly.
