Factory Acceptance Checks for a Vacuum Gas-Quenching Furnace
Buyers should define measurable pass or fail checks for temperature range, load handling, and gas pressure before signing off a vacuum gas-quenching furnace at the factory.
Before signing the factory acceptance test, decide which checks must pass on the floor and which can be verified by document. For a vacuum gas-quenching furnace serving steel heat treatment, start with the working range of 500–1,300 °C: ask the supplier to demonstrate control at a low and a high setpoint and to show how uniformity is recorded, rather than accepting a single warm-up reading.
Next, tie the load envelope to the test. The catalog reference values are 600 × 600 × 900 mm and 600 kg including fixture, and a maximum gas pressure of 6 bar absolute. Ask whether the acceptance load will be a dummy fixture at the stated maximum, and whether quench pressure will be demonstrated at 6 bar absolute or at a lower agreed value. Clarify which instruments are calibrated, how readings are logged, and what tolerance counts as a fail.
Before requesting a quote, confirm with the supplier which tests are included, what load and pressure will be used, how results are documented, and who witnesses the acceptance test.
