Heat Treatment, Furnaces & Thermal Processing calculator
Quench Tank Capacity Calculator
Estimate good quench tank capacity from loads per quench cycle, usable quench cycles, tank uptime, and accepted quench yield. It shows realistic good output after uptime and first-pass yield, not just the furnace nameplate or theoretical schedule.
What this calculator does
- Estimate good quench tank capacity from loads per quench cycle, usable quench cycles, tank uptime, and accepted quench yield.
- Use it when oil, polymer, water, salt, or gas quench capacity limits hardening throughput.
- Estimates how many accepted loads can be quenched in a shift.
Formula used
- Gross quench tank capacity = loads per quench cycle × usable quench cycles
- Good quench tank capacity = gross capacity × quench tank uptime × accepted quench yield
Inputs explained
- Loads per quench cycle: Use the accepted parts, loads, tests, or batches completed each cycle.
- Usable quench cycles: Use usable cycles after warm-up, setup, transfer, maintenance, and planned stops.
- Quench tank uptime: Use recent uptime or availability for the same furnace, line, or test station.
- Accepted quench yield: Use first-pass yield after inspection, hardness, case depth, profile, distortion, or release checks.
How to use the result
- Use it for hardening line balancing, quench tank staffing, media maintenance planning, and bottleneck checks.
- It does not calculate cooling severity, agitation, bath temperature, or metallurgical results. Verify those separately.
Common questions
- What is the quench tank capacity calculator for? It estimates shift capacity for the quench step.
- What numbers should I enter? Use loads per quench cycle, usable cycles, tank uptime, and accepted quench yield.
- How should I use the result? Use the result to decide whether quench capacity can support the furnace schedule.
- When is this only an estimate? It is only an estimate when bath temperature recovery, agitation, fixture handling, or media condition changes.
