Input Data Mass kg Density g/cm³ Initial gas pressure Bar(g) Residual metal height at the end mm Number of holes pc Diameter of one hole mm Calibration / Machine constants Flow coefficient Cd — Calibration coefficient — Inner diameter of the crucible mm Height of crucible mm Calculate Reset defaults Tip: if you only want to compensate for hydrostatics, leave the initial gas pressure at 0 Bar(g). Results Recommended starting pressure 0.000 Bar(g) Recommended pressure at the end 0.000 Bar(g) Ramp / drain duration 0.00 s Duration in [m]:ss 0:00 formatted time OK Cross-sectional area of the crucible Metal volume Initial height of metal Filling degree of the crucible Hydrostatic pressure at the beginning Hydrostatic pressure at the end Target total pressure on the holes Total area of holes Flow rate while maintaining constant pressure Volume drained Pressure increase per cycle Pressure and melt height during the cycle Gas pressure Metal height Accepted assumptions The machine performs a linear pressure ramp from the initial to the final value. The ramp is selected so that the total pressure on the holes is approximately constant. The flow rate is then treated as constant, and the ramp time is taken equal to the drain time. Viscosity, wetting, oxide film and geometric losses are included only through the flow coefficient Cd and the calibration coefficient. The model is useful for setup and comparison, but a real-machine calibration run is still recommended.
