Newly purchased or reconstructed electrode salt bath furnaces should be dried out. They can be baked using a resistance wire pan, with staged heating and maintenance of temperature to prevent the concrete bath from cracking.
(2) Ensure the ventilation system is activated during work hours, and cover the furnace mouth in case of power outages.
(3) The furnace shell and transformer should be properly grounded. The copper bars and electrode handles must have good contact. Inspect for any leakage or short circuits in the bath tank, electrodes, electrode handles, transformer, and water cooling system. Clean the furnace of any adhered salt, oxide scales, and other debris.
(4) Maintain a high brine level to ensure even and rapid heating of the workpiece. Oxygen should be removed promptly, slag should be removed, and sufficient fresh salt should be added.
(5) In the event of temporary shutdown due to difficulty in starting the electrode salt furnace, cover the furnace mouth and maintain heat under low voltage power supply; for prolonged power outages, remove some of the salt liquid and place the starting device.
(6) Prevent workpieces from falling into the bath to avoid short circuits. Disconnect and remove workpieces that fall into the furnace. Maintain a distance from the electrodes, bath side walls, furnace bottom, and liquid surface when loading workpieces into the furnace.
(7) Automatic temperature control devices should be used.
(8) Pay attention to the transformer's operating conditions, avoid overloading, prevent oil leakage, and do not allow the core to overheat or the oil temperature to rise too high.
