Multi-Functional Refining agent Probat-Fluss Al 2126

Sodium-free cleansing and skimming agent potassium based, for all low-silicon and hypereutecti c aluminium alloys, such as: G-AlMg3, G-AlCu4Ti, G-AlSi17Cu4Ti and G-AlSi18CuNiMg as well as aluminium wrought alloys.

Applicati on Range:
PROBAT-FLUSS AL 2126 is applicable for all casti ng processes, however, preferably for alloys which are free from sodium. It stands out by good storage stability and a wide reacti on range (between 700°C and 800°C, higher temperatures reduce the reaction time).
Quality Characteristics:
• removes oxides from the melt by fl otati on and reduces the hydrogen content
• produces a fi ne, 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
• suitable for the automati c dosing with an impeller system
Additi on Rate:
Depending on the level of impuriti es 0.05–0.25 % by weight or lower
Product Application:
PROBAT-FLUSS AL 2126 works in melting, holding and pouring furnaces as well as in crucibles. When using as a cleansing agent, submerge the required additi on into the melt (during the impeller treatment or when decanting).
Gently stir with a well pre-heated and coated tool unti l a fully reacted dross forms and then skim it off .
For the dross treatment, distribute PROBAT-FLUSS AL 2126 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 times 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 essenti ally. Thus, more metal is available for the casting process (metal saving potenti al). The addition of the agent in the pouring stream while decanting increases this eff ect.
