Pour Temperature Window with available temperature window time of 3 hr: a worked example

This scenario runs the pour temperature window calculation on the strong side: available temperature window time of 3 hr, with every other input held at its documented default. Use it when pour temperature affects misruns, cold shuts, shrinkage, gas defects, metallurgical properties, or mold damage.

The inputs for this scenario

  • Available temperature window time: 3 hr (raised for this scenario; the documented default is 1.2)
  • Required transfer and pouring time: 0.75 hr (unchanged)
  • Temperature safety buffer: 0.2 hr (unchanged)

Working through the calculation

  • Applying the documented formula (Remaining pour temperature window buffer = available temperature window time - required transfer and pouring time - temperature safety buffer) to the inputs above produces each figure below.
  • At this operating point the engine returns 0 outside for inside window, the number this scenario is built around.
  • At this operating point the engine returns -2.25 value for nearest margin.
  • At this operating point the engine returns 0.75 value for lower limit.
  • At this operating point the engine returns 0.2 value for upper limit.

How this compares with the baseline

  • Against the tool's baseline example, where available temperature window time sits at 1.2 hr and the headline result is 0 outside, this scenario lands almost exactly on the baseline at 0 outside.
  • Use it before committing to a transfer route or ladle size, especially for large or thin-section castings where the window is tight. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Inside window: 0 outside (headline result)
  • Nearest margin: -2.25 value
  • Lower limit: 0.75 value
  • Upper limit: 0.2 value
