| The MINCO
ProAS sampling system gives extremely reliable and representative
sample quality.
Originally developed as an essential device for high quality
steelmakers it has also proved an invaluable tool for all
producers requiring clean and highly representative samples.
The initial argon purge removes contamination from the sample
fill area (slag, capping material, insulation powder etc.),
before a vacuum is applied to allow the sample to fill with
clean molten metal.

| State of the art
sampling for improved analysis
- Argon stirred sampling provides more clean, representative
and homogeneous samples in comparison to standard sampler
applications. The higher sample quality allows the steel
producer to stay closer to specifications, allowing production
of steel qualities unattainable using standard sampling
methods with analysis variation.
- The system is especially recommended for ULC- and alloy
steel melts, where typically the contamination and dilution
effects have a significant impact on the validity of analysis.
- The improved sample surface gives better sample yield
and reduces the typically required grinding depth from
1 mm to 0,3 mm.
- Experiences shows that in particularly difficult conditions
where the metal is close to liquidus temperature, the
ProAS system gives better sampling performance. The fill
entry is preheated during the stirring phase, which reduces
the risk of the fill pin freezing before the sample chamber
is full.
- The automatic control system minimises the effect of
operator error and improves the yield of good samples.
- The ProAS system is especially recommended for secondary
steelmaking application at the ladle, tundish and mold.
