Does queue time include the heat treatment cycle?

No. Queue time ends when the new load starts processing.

Which loads belong in the backlog?

Count loads that will be released ahead of this job on the same constrained route.

Use the observed release rate. Rated capacity can miss staging, quench and inspection constraints.

Enter zero queued loads. Only the separately entered hold remains in the projected wait.

Heat Treatment, Furnaces & Thermal Processing calculator

Estimate the time needed to release the loads ahead of your job. Enter the backlog, observed release rate, separate holds and your wait limit.

Project how long a new heat treat load waits behind the staged backlog and scheduled extra holds.

Queued Loads Ahead: Count staged loads ahead of the new load.
Observed Load Release Rate: Completed staging releases divided by the matching observation hours.
Additional Hold Time: Scheduled holds absent from the observed release rate.
Maximum Queue Wait: Your permitted wait before this load starts processing.

A changing recipe mix, downtime or arrivals with priority can invalidate this projection. This is a backlog estimate, not a statistical waiting-time guarantee.

Industrial electricity averages 9.77 cents per kWh across the U.S. (EIA, Jul 2026), up 4.7% from a year earlier. Energy-intensive steps carry this directly into unit cost.

Can I use the rated furnace capacity? Use the observed release rate. Rated capacity can miss staging, quench and inspection constraints.
What if no loads are waiting? Enter zero queued loads. Only the separately entered hold remains in the projected wait.
