A threaded high alumina cup that takes a master sample and a pin sample at once, without machining.
One cup, two samples,
and no machining before the lab can start work.
Sample cups that survive molten metal sampling are made of a thermal shock resistant, erosion resistant ceramic, so the cup neither cracks on immersion nor gives material to the sample. The Blasch sample cup is a single piece of fired high alumina ceramic that takes a 1-3/8 in master sample for chemical analysis and a 1/4 in pin sample for gas analysis in one dip. A 1/2 in NPT tapered thread screws it onto a length of steel pipe as the handle.
Side fill master sample: metal enters from the side into a chamber 5 in deep. Dross and impurities rise to the top before the sample solidifies, so the bottom section can be sliced off as a clean sample for chemical analysis.
Bottom fill pin sample: a separate 1/4 in chamber fills from below. Metal from under the surface gives a cleaner sample for gas analysis.
Threaded connection: the cup threads onto ordinary steel pipe, so the handle stays and only the cup is replaced.
A sample is only worth its analysis if the cup added nothing to it and took nothing away, which is why the cup is made from the same kind of ceramic as the crucible.
Consistent cups give consistent samples, and that shortens the path from furnace to result.
Each cup is cast to the same dimensions, so every sample fits the same preparation and test setup.
Both samples come out at their final diameter, which removes steps before analysis.
Resistance to erosion and attack by the melt keeps ceramic out of the sample.
In induction melting of superalloys and specialty steels, where chemistry is checked before the pour and gas content matters for the finished part. The cup is part of the same range as ProCaster high alumina crucibles and the InterLok segmented lining.
The master sample, 1-3/8 in in diameter, is used for chemical analysis. The pin sample, 1/4 in in diameter, is used for gas analysis.
With a 1/2 in NPT tapered thread that screws onto a length of steel pipe.
