Slitting Yield at 71% target slitting yield: a worked example

This worked example runs the slitting yield numbers for a tougher week than the baseline: 71% target slitting yield instead of the typical 98%. Calculate slitting yield by comparing the prime weight of the finished mults against the master coil weight you slit, after edge trim and crop loss.

The inputs for this scenario

  • Prime mult weight: 24,500 lb (held at the documented default)
  • Master coil weight slit: 25,000 lb (held at the documented default)
  • Target slitting yield: 71 % (the input this scenario stresses; the baseline uses 98)

Working through the calculation

  • The calculation starts from the formula this tool documents: Slitting yield = prime mult weight ÷ master coil weight slit × 100.
  • Slitting yield works out to 98 % at these inputs, and this is the headline figure for the scenario.
  • Yield gap to target works out to -27 points at these inputs.
  • Prime mult weight works out to 24,500 count at these inputs.
  • Master coil weight slit works out to 25,000 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target slitting yield sits at 98% and the headline result is 98 %, this scenario lands almost exactly on the baseline at 98 %.
  • Use it after each coil or shift to confirm recovery, when validating a new slitting schedule's trim allowance, or when investigating a scrap spike on the line. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Slitting yield: 98 % (headline result)
