Shrinkage Prevent Agent for Gravity Casting

PROBAT-FLUSS MIKRO 100

Agent to prevent shrinkage holes and the formation of homogenously distributed micro pores.

applicable for all casting alloys in the sand casting, gravity die casting and low-pressure casting

Applicati on Range:

PROBAT-FLUSS MIKRO 100 can be added to the crucible, the launder or the runner after the cleaning of the melt.

The rod dissolves immediately without any residues. A thorough mixing of the melt after the last cleaning process has proved to be very effective.

Quality Characteristics:

• is a metallic master alloy in form of rods

• does not require long reaction times

• impedes the shrinkage hole formation in the gravity die and sand casting

• leads to fine micro pores

• increases the density index without contribution to impurities

• dissolves immediately in the melt without any residues

Addition Rate:

1–3 kg/t of the metal mass, depending on the alloy. As a general rule 1 kg/t has proved to be very effective.

Product Application:

PROBAT-FLUSS MIKRO 100 can be used in the pouring furnace, in the crucible or in the ladle.

After the last cleaning process it must be added to the melt and the foam, which can partially form, must be thoroughly stirred into the melt by means of a ladle otherwise the effectivity is reduced. The effect lasts over several hours and is also remarkable after a remelting process. After an intensive cleaning, the melt is in its original condition again.
