H-Scan

Robusto, preciso y económico

La presencia del hidrógeno en el aluminio derretido acarrea problemas a las industrias de fundición y moldeado, ya que el alto residuo de hidrógeno puede conllevar porosidad considerable después de la fundición, lo que ocasiona rechazos o el riesgo de fallas mecánicas. El H-Scan facilita mejorar sustancialmente la calidad y confiabilidad de la fundición de aluminio propiciando el control preciso del hidrógeno contenido en el aluminio fundido justo antes de su moldeado. Sin falta ni exceso de desgasificación. Sin rechazos y sin pérdidas de tiempo o dinero. El analizador H-Scan de Metal Power se ha construido para analizar rápida y precisamente el hidrógeno contenido en el aluminio fundido, y cuenta con varias funciones únicas. El H-Scan usa la técnica de presión reducida para medir el contenido de hidrógeno. Al controlar la solidificación, la presión parcial de todo el hidrógeno liberado es medida con precisión y relacionada con su porcentaje. El H-Scan proporciona información cuantitativa precisa dentro de los 3 minutos posteriores al muestreo, permitiendo que los usuarios optimicen el nivel de desgasificación. Con un costo de análisis de tan solo 7 centavos (INR 5), el H-Scan es uno de los instrumentos más económicos del mundo y su exactitud está también entre los mejores (dentro del 5 % del método de sobrefusión al vacío), por lo que es la solución óptima para todo tipo de usuarios que buscan la calidad. H-Scan viene acompañado de una garantía de alta calidad, confiabilidad y los niveles más altos de servicio de Metal Power.

(English) H-Scan provides measurement accuracy within 5% of the vacuum sub-fusion method. While Vacuum sub-fusion is considered the reference method for the highest accuracy, it remains both very slow and extremely expensive and largely restricted to laboratories. For industry applications therefore, H-Scan provides the most accurate results of any instrument / method. Indeed, the H-Scan also has an in-built weighing station, the output of which is used by the computer to even correct the value for weight differences across samples!

Also, unlike the low-cost first-bubble systems, the H-Scan is fully automated. This ensures that:
a. No manual error is possible: There is no manual step involved and all tasks after starting the analysis are fully computer-controlled.
b. Database is stored on the computer: This ensures that all results are extremely accurate and granular.

(English) One of the key issues with Hydrogen measurement in the melt is traceability. It’s impossible to have CRMs of molten metal, making most instruments impossible to calibrate or test for accuracy. This however does not apply to the H-Scan. Metal Power being an NABL-accredited for Laboratory (Proficiency Testing Provider, Wet Chemical Lab, Instrumentation Lab and CRM) has ensured that the H-Scan is fully traceable and that it can be tested and calibrated on-site with minimum cost and fuss.

The instrument is supplied with certified calibrated pipettes that can be used for quick checking of accuracy and can also be used for correcting the calibration if needed. Further, given the simplicity of this process, it can be carried out on-site by the operators or engineers as well, without requiring an expensive shipment to a Laboratory.

(English) With a cycle time of just 3 minutes, the H-Scan provides reliable outputs to the user well in time to make changes to the melt. Also, since the process is computer-controlled, the results are highly reliable – and have the highest levels of accuracy and traceability.

Also, results of analyses are stored on the computer and can be readily retrieved for ensuring traceability over time.

(English) The H-Scan requires virtually no consumables. No expensive probes are used and the only consumable item is a thin SS wire. Including energy costs, oil for the vacuum pump etc. therefore, the instrument delivers an operating cost of just INR 5 per analysis! This compares favourably with every single quality solution in the market, while still delivering higher accuracy and traceability than all of them!
