Remelting Refining Flux SY-CRJ1

SY-CRJ1

FEATURE DESCRIPTION:

This product is formulated from a blend of saline compounds via specialized chemical engineering processes, is precisely injected into molten aluminum using nitrogen or argon as carrier gases through powder injection systems. This mechanism enables dual-phase purification of the aluminum melt through synergistic gas-flux reactions, effectively eliminating hydrogen porosity and oxidic inclusions to achieve superior melt cleanliness. The product exhibits extensive application potential in the secondary aluminum smelting sector as a high-performance metallurgical refining flux.

Main Advantages

◀ Adopts an environmentally friendly formula, ensuring smoke-free, odorless, and dust-free operation during use while reducing harmful gas emissions.

◀ Compared to traditional refining flux, it ensures refining efficiency while significantly reducing slag output during application.

◀ The new formula incorporates low-melting-point substances, which effectively lower the reaction melting point and reduce operating temperature, contributing to energy conservation and consumption reduction.

◀ Rapidly aggregates slag to form a loose slag layer, enabling efficient separation of slag and aluminum, thus significantly reducing the aluminum content in aluminum dross.

◀ After the refining process, the residual content of the refining flux in the molten metal is extremely low, with residual components controlled at minimal levels, causing no significant interference with key properties of aluminum alloys such as electrical conductivity and corrosion resistance.

Usage Method

◀ Manual Spreading Method (suitable for small-scale furnaces):

Evenly spread the refining flux over the surface of molten aluminum, then rapidly submerge it into the deep molten pool using a perforated tool; thoroughly agitate for 5 minutes to achieve complete flux dispersion; allow a 10-15 minute settling period prior to thorough slag removal.

◀ Inert Gas Injection Method (suitable for large-scale/automated production lines):

Within the optimal refining temperature range, load the metered refining flux into the powder injector's hopper and secure the lid. Introduce nitrogen gas supply and activate the injector valve. Upon observing flux discharge from the lance tip, submerge the lance into the molten aluminum and execute horizontal, vertical, or arcuate traversal motions. Complete the flux injection cycle within the specified refining duration, then retract the lance from the melt and terminate the nitrogen flow.
