Wire Drawing & Rod Processing worked example

Tensile Draw Ratio with entry cross-section of 250 units: a worked example

What does the result look like when entry cross-section reaches 250 units? The full calculation is worked below with real intermediate numbers. Use it when tensile draw ratio in wire drawing and rod processing needs a few factors combined into one defensible number for wire drawing and rod processing.

The inputs for this scenario

  • Entry cross-section (or area factor): 250 units (raised for this scenario; the documented default is 100)
  • Reduction / draw factor: 4 units (unchanged)
  • Area-to-ratio conversion factor: 0.01 x (unchanged)
  • Process efficiency multiplier: 1 x (unchanged)

Working through the calculation

  • Applying the documented formula (Tensile Draw Ratio = first factor × second factor × conversion factor × process multiplier) to the inputs above produces each figure below.
  • At this operating point the engine returns 5 units for result, the number this scenario is built around.
  • At this operating point the engine returns 5 value for base product.
  • At this operating point the engine returns 1 x for multiplier.
  • At this operating point the engine returns 1,000 value for factor a x b.

How this compares with the baseline

  • Against the tool's baseline example, where entry cross-section sits at 100 units and the headline result is 2 units, this scenario comes in 150% above the baseline at 5 units.
  • A figure at this level is achievable when entry cross-section is genuinely sustained, not just peaked for a shift. It's a linear product of factors, not a metallurgical model; it won't predict absolute tensile strength or account for material grade, anneal state, or die-angle effects on its own.
