Quench Tank Capacity at 66% quench tank uptime: a worked example
Suppose quench tank uptime falls to 66%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate good quench tank capacity from loads per quench cycle, usable quench cycles, tank uptime, and accepted quench yield.
The inputs for this scenario
- Loads transferred per quench cycle: 1 loads / cycle (held at the documented default)
- Usable quench cycles per shift: 32 cycles / shift (held at the documented default)
- Quench tank uptime: 66 % (the input this scenario stresses; the baseline uses 92)
- Accepted yield after quench inspection: 96 % (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Gross quench tank capacity = loads per quench cycle × usable quench cycles.
- Good quench tank capacity works out to 20.28 loads / shift at these inputs, and this is the headline figure for the scenario.
- Gross quench capacity works out to 32 loads / shift at these inputs.
- Quench downtime loss works out to 10.88 loads / shift at these inputs.
- Quench reject loss works out to 0.84 loads / shift at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where quench tank uptime sits at 92% and the headline result is 28.26 loads / shift, this scenario comes in 28.26% below the baseline at 20.28 loads / shift.
- It computes good quench tank capacity as loads per cycle times usable cycles per shift, then derated by tank uptime and accepted yield. 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.
