The melting loss in an induction furnace, especially when melting aluminum, is influenced by several factors.
These factors include electrical and thermal efficiencies, transmission and transformation losses, and the oxidation rate during the melting process.
What is the melting loss in induction furnace? (4 Key Factors Explained)
1. Electrical Efficiency
Electrical efficiency refers to the energy loss associated with the current flowing in the inductor.
This is the main loss in the system.
The loss is primarily due to the structure of the inductor, the physical properties of the charge (aluminum), and the heating frequency.
Electrical efficiency is the ratio of the energy transferred to the workpiece (aluminum) to the energy the inductor receives from the power source.
In an intermediate frequency aluminum melting furnace, the efficiency is reported to be around 62%.
2. Thermal Efficiency
Thermal efficiency loss occurs due to the heat dissipation of the heated workpiece (aluminum) to the surroundings.
This is the second most significant loss after the inductor loss.
Thermal efficiency is the ratio of the net heat that heats the workpiece to the total heat that the workpiece receives from the induction coil.
In the case of aluminum melting, the thermal efficiency can reach up to 75%.
3. Transmission and Transformation Losses
These are additional losses that occur in the power supply system.
Transmission loss is the loss caused by the cables and bus bars that supply power from the variable frequency power supply to the load.
This loss is generally between 2% to 7%.
Transformation loss is the loss of the converter components, filter inductors, commutation inductors, and compensation capacitors in the power cabinet.
This typically ranges from 2% to 5%.
4. Oxidation Melt Loss
The oxidation rate during the melting process also impacts the overall melting loss.
Core type induction furnaces are noted to reduce the amount of oxidation that occurs during melting.
This leads to lower rates of loss and a higher yield overall.
This aspect is crucial when considering the efficiency and material loss in the melting process.
