Foundry & Forging calculator
Pour Temperature Window Calculator
Check whether molten metal temperature remains inside the acceptable pouring window after transfer, hold, and setup time. Use it when pour temperature affects misruns, cold shuts, shrinkage, gas defects, metallurgical properties, or mold damage.
What this calculator does
- Check whether molten metal temperature remains inside the acceptable pouring window after transfer, hold, and setup time.
- Use it when pour temperature affects misruns, cold shuts, shrinkage, gas defects, metallurgical properties, or mold damage.
- Checks schedule fit for pour-temperature control.
Formula used
- Remaining pour temperature window buffer = available temperature window time - required transfer and pouring time - temperature safety buffer
- Positive buffer means the work fits inside the available window.
Inputs explained
- Available temperature window time: Enter allowed time before the metal is expected to fall outside the approved pour temperature range.
- Required transfer and pouring time: Use tap-to-pour, ladle transfer, mold filling, sampling, and temperature-check time.
- Temperature safety buffer: Add buffer for ladle waits, chemistry holds, crane delays, mold delays, and pyrometer uncertainty.
How to use the result
- Use before changing pouring sequence or ladle practice.
- This calculator is an estimating tool. Results can change with alloy chemistry, furnace practice, ladle losses, mold design, gating and riser layout, core condition, pattern allowance, die temperature, press condition, inspection criteria, rework rules, energy rates, labor standards, and actual shop performance. Validate safety-critical, metallurgical, tooling, press-capacity, and customer-spec decisions with qualified engineering, metallurgy, OEM data, and the applicable control plan.
Common questions
- What information do I need before using the Pour Temperature Window? Use available temperature window, required transfer/pour time, and safety buffer.
- What does the result mean? It shows whether pouring fits before temperature risk becomes unacceptable.
- When is the result only an estimate? This calculator is an estimating tool. Results can change with alloy chemistry, furnace practice, ladle losses, mold design, gating and riser layout, core condition, pattern allowance, die temperature, press condition, inspection criteria, rework rules, energy rates, labor standards, and actual shop performance. Validate safety-critical, metallurgical, tooling, press-capacity, and customer-spec decisions with qualified engineering, metallurgy, OEM data, and the applicable control plan.
- What decision can I make from the result? Use it to adjust ladle routing, preheat, pour sequencing, or hold-time rules.
