Before melting, the preheating of the medium frequency induction melting furnace is essential. It ensures the furnace has a long service life. The preheating process for a medium frequency induction melting furnace typically involves several steps.
Before starting the preheating process, ensure that the power supply to the furnace is switched off and that all safety measures are in place.
Visually inspect the furnace to ensure that it is free of any debris or foreign objects that could affect its performance.
The lining of the furnace should be prepared by applying a coating of refractory material. This will help to protect the lining from the high temperatures generated during the melting process.
Once you have completed the above steps, switch on the power supply to the furnace.
Set the frequency and power to the required levels for the preheating process. This will depend on the type of material being melted and the size of the furnace.
Monitor the temperature of the furnace using a pyrometer or other temperature-measuring device. The temperature should be slowly increased until it reaches the desired level for the melting process.
After each preheating, you only need to keep the electric furnace running. Unless the furnace is shut down or the crucible is damp again, there is no need to preheat again.
Once the desired temperature has been reached, maintain it for a period of time to allow the furnace to reach thermal equilibrium.
Once the preheating process is complete, the furnace is ready to be used for the melting process. Add the material to be melted and adjust the power and frequency as necessary to achieve the desired melting rate and temperature.
It's important to follow all safety procedures and guidelines when working with an induction melting furnace, as the high temperatures and electrical currents involved can be hazardous. It's also important to consult the manufacturer's instructions and guidelines for your specific furnace model to ensure that you are following the correct procedures for preheating and operating the furnace.
Heating temperature is between 200-1400 degrees.
Induction billet furnaces can heat billets to temperatures ranging from room temperature to over 1200°C.
After the Slab is pulled out from the continuous casting machine,Surface temperature is 750 ~ 850℃.
Induction online heating of large steel pipes is widely used in the heat treatment of various high alloy steel pipes required in oil drilling, geological drilling, coal mining, infrastructure exploration and other fields.
