CERAFLUX-40 is a powder flux suitable for all types of aluminium alloys. It is a composite of magnesiu and potassium salts. It reacts quickly to efficiently remove Na, Li, and Ca from molten Al and Al-Mg alloys.
- Sodium and fluoride-free
- CERAFLUX-40 has a low melting point for rapid dissolution
- To remove sodium from the refractory linings of holding furnaces.
Thoroughly remove any dross from the furnace lining. Sprinkle CERAFLUX-40 evenly over the refractory to be treated prior to introducing aluminium. Apply 2- 3kg of flux per square meter of refractory . Add the metal to the furnace and repeat this procedure for the next 5 to 6 casts.
- To remove sodium from molten aluminium in the holding furnace.
In addition to the treatment of the furnace lining, inject between 1 to 5 kg of CERAFLUX-40 for each metric tonne of aluminium. When there is no risk of sodium contamination in the holding furnace, CERAFLUX-40 can be used to treat molten aluminium in the transfer ladle bringing metal from the melting furnace. Add CERAFLUX-40 to the empty ladle at a rate of 1-5 kg per tonne of aluminium. Fill the ladle with aluminium and add sufficient CERAFLUX-40 to the metal surface to provide a continuous protective layer. Inject nitrogen or argon for approximately 10 minutes to thoroughly stir and clean the metal. Skim the ladle with a suitable skimming tool before transferring the metal into the holding furnace.
650 ºC and higher.
Exact requirements will depend on the initial and targeted levels of Na, Li, and Ca.
Flux is highly hygroscopic in nature to be stored in a dry place. Close opened
