FAT Checks for a Medium-Frequency Induction Melting Furnace
Buyers should define measurable pass or fail checks for a 0.5 t, 1,000 Hz, 250 kW induction melting furnace before the factory acceptance test, covering power, melting, cooling, and controls.
For a 0.5 t medium-frequency induction melting furnace, the key buyer decision is which checks at the factory acceptance test prove the unit is ready for metal melting, rather than merely running. Agree the pass or fail criteria in the purchase order before the test, so the demonstration is judged against stated values.
Ask the supplier to state the test metal and charge weight, then confirm the furnace reaches the rated power of 250 kW at the operating frequency of 1,000 Hz. A practical pass check is a timed melt of a defined charge to a defined temperature, with the result recorded against the supplier's declared melt time. For cooling, verify flow and temperature interlocks trip the power as intended. For controls, confirm alarms, power ramps, and emergency stop behave as described. During the demonstration, ask whether the nominal melt capacity of 0.5 t is a holding or full-melt figure, and require the supplier to clarify it in writing.
Before requesting a quote, confirm with the supplier which checks they will perform at the factory, what instrumentation and records will be provided, and how deviations are resolved.
