Excessive smoke during fluxing? Use Schaefer fluxes!
Fluxing is a critical step in aluminum melting and die-casting operations. It plays an important role in cleaning molten aluminum, removing non-metallic inclusions, reducing dissolved hydrogen, and improving overall metal quality. However, one common operational challenge faced by many foundries is excessive smoke during the fluxing process, a problem that affects safety, visibility, environmental compliance, and operator comfort.
What causes excessive smoke during fluxing?
The primary cause is the use of exothermic, nitrate-based flux chemistry. Traditional exothermic fluxes often contain nitrates or oxidizing agents that react violently when introduced into molten aluminum. This reaction releases a large amount of heat and gas in a very short time, resulting in:
What are the advantages of non-exothermic flux chemistry?
Schaefer fluxes as the solution!
Schaefer has developed a range of fluoride-based, non-exothermic fluxes specifically engineered to address excessive smoke issues without compromising cleaning efficiency.
By reducing smoke during fluxing, it impacts worker’s health and safety, environmental compliance, furnace cleanliness, metal recovery and cost efficiency. For expert guidance and product recommendations tailored to your operation, contact PT Wilisindomas Indahmakmur.
