Top Grade K-based refining agent PROBAT-FLUSS AL 3125
Sodium-free, highly compacted cleansing and skimming agent potassium based, for all low-silicon and hypereutectic aluminium alloys
such as e. g.: G-AlMg3, G-AlCu4Ti, G-AlSi17Cu4Ti and G-AlSi18CuNiMg
Applicati on Range:
PROBAT-FLUSS AL 3125 is applicable for all casting processes, however, preferably for alloys which are free from sodium. It stands out by good storage stability and a wide reaction range (between 700°C and 800°C).
• removes oxides from the melt by flotati on and reduces the hydrogen content
• forms mixing phases with the oxides and adheres to the oxide by energetically low surface tension
• prevents the formation of corundum and its adherences
• produces a fine, powdery and low-metal dross
• works in all types of furnaces and crucibles
• permits the easy removal of adherences
• is of very low smoke and odour emission
Depending on the level of impurities 0.05 – 0.25 % by weight or lower (rule of thumb: half the quantity compared with the powder addition)
PROBAT-FLUSS AL 3125 works in melting, holding and pouring furnaces as well as in crucibles. When using as a cleansing agent, submerge the required addition into the melt (during the impeller treatment or when decanting).
Gently stir with a well pre-heated and coated tool until a fully reacted dross forms and then skim it off .
For the dross treatment, distribute PROBAT-FLUSS AL 3125 on the surface and stir the agent in the dross with a tool.
Skim it off aft er a reacti on ti me of three minutes. When it is used regularly (one to two ti mes per shift ) it impedes the formation of built-ups on the furnace walls and crucibles.
During the impeller treatment oxides are bound and the metal content in the dross is reduced essentially. Thus, more metal is available for the casting process (metal saving potential). The additi on of the agent in the pouring stream while decanting increases this effect.
Appearance: white granules
Reaction temperature: between 700°C and 800°C (higher temperatures reduce the reaction time)
Packaging: 25 kg bags, 3-fold with plastics lining, special packaging available.
Storage and Shelf Life:
Store in a cool place (below 32°C/90°F); keep container dry and tightly closed. The shelf life is at least 6 months if properly stored.
