Pour Temperature Window with available temperature window time of 0.6 hr: a worked example

Suppose available temperature window time falls to 0.6 hr. This page works the full calculation at that level so you can see exactly which result moves and by how much. Check whether molten metal temperature remains inside the acceptable pouring window after transfer, hold, and setup time.

The inputs for this scenario

  • Available temperature window time: 0.6 hr (the input this scenario stresses; the baseline uses 1.2)
  • Required transfer and pouring time: 0.75 hr (held at the documented default)
  • Temperature safety buffer: 0.2 hr (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Remaining pour temperature window buffer = available temperature window time - required transfer and pouring time - temperature safety buffer.
  • Inside window works out to 0 outside at these inputs, and this is the headline figure for the scenario.
  • Nearest margin works out to -0.15 value at these inputs.
  • Lower limit works out to 0.75 value at these inputs.
  • Upper limit works out to 0.2 value at these inputs.

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.
  • It subtracts required transfer-and-pour time and a temperature safety buffer from the available castable window to show whether the pour fits and by how much. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Inside window: 0 outside (headline result)
  • Nearest margin: -0.15 value
  • Lower limit: 0.75 value
  • Upper limit: 0.2 value
