Metal Recycling, Scrap Processing & Salvage worked example

Melt Loss Estimate at 68% target melt loss rate: a worked example

Suppose target melt loss rate falls to 68%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate melt loss estimate for metal recycling, scrap processing and salvage using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Metal lost in melt (count): 8 count (held at the documented default)
  • Total charge into the furnace: 250 count (held at the documented default)
  • Target melt loss rate: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Melt loss estimate rate = melt loss estimate count ÷ total melt loss estimate population × 100.
  • Melt loss estimate rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Melt loss estimate gap to target works out to 64.8 points at these inputs.
  • Melt loss estimate count works out to 8 count at these inputs.
  • Total melt loss estimate population works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target melt loss rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • It expresses lost metal as a percentage of the total furnace charge, then reports the gap between that rate and your target rate. 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.
