High Degree of Automation and Intelligence
Medium frequency induction furnaces are equipped with a PLC control system, enabling a semi-automated / fully automated process that covers "one-click startup - power adjustment - temperature monitoring melting completion alarm":
Temperature Monitoring: The molten pool temperature is collected in real time via an infrared thermometer or thermocouple, and the data is directly displayed on the control panel. This eliminates errors and safety risks associated with manual temperature measurement.
Power Adjustment: The output power is automatically adjusted according to the melting stage (e.g., high power is required for rapid heating during the "material melting period," and low power for heat preservation during the "refining period"), thereby reducing electricity waste.
Fault Protection: In case of abnormalities such as "overcurrent," "water shortage," or "thinning of furnace lining," the system will immediately cut off the power supply and trigger an alarm to prevent equipment damage or safety accidents.
High Operational Safety Factor
Compared with traditional flame furnaces (which pose risks of open flames, high-temperature flue gas, and fuel leakage), medium frequency induction furnaces have significant safety advantages:
They use electric energy instead of fuel and produce no open flames, eliminating risks such as fuel explosions and gas leaks.
The furnace shell is wrapped with thermal insulation materials (e.g., firebricks, insulation cotton), allowing the surface temperature to be controlled between 50-80℃ (only slightly higher than room temperature) and reducing the risk of scalding for operators.
High-voltage components of the medium frequency power supply (such as transformers and capacitors) are equipped with enclosed protective casings to prevent electric shock.
