Characterisation of Molten Metal Quality Using the Pressure Filtration Technique

Molten metal quality in terms of consistency, sensitivity to metal disturbance, in-line metal treatment and additions practice has been characterised using the pressure filtration technique called PREFIL-Footprinter. The reproducibility of the data is discussed and compared with the benchmarks for A356. The pressure filtration instrument resolves small changes due to operator interventions upstream and diagnoses issues related to strontium and grain refiner additions downstream.
