Efficiency and loss of medium frequency induction melting furnace

1、Heating loss caused by flow through the inductor: the loss is carried away by cooling water. This loss is the main loss of the system, which is related to the structure of inductor, the physical properties of furnace charge and the frequency of heating. The electrical efficiency is the ratio of the energy transferred to the heated workpiece and the energy that the inductor receives from the power.

2、Heating loss: the loss caused by the heat dissipation of the heated workpiece, which is only inferior to the inductor loss. The "thermal efficiency" is often used to describe this loss, and the thermal efficiency is the ratio of the net heat to the total heat that the workpiece receives from the induction coil.

3、Transmission loss: loss caused by power cables and busbars supplied from a variable frequency power supply to a load, usually between 2% and 7%.

4、Conversion loss: the loss of converter elements, filter inductors, commutating inductors and compensation capacitors in the power cabinet is generally between 2% and 5%.

Our factory intermediate frequency furnace has an electric efficiency of 62%, a thermal efficiency of 75%, a frequency conversion loss of 3%, and a transmission loss of 5%.

Working Principle

The basic principle of induction heating is adopted in the medium frequency smelting furnace of aluminum shell. "Induction heating" is the method of heating the load by induction current in the load itself by electromagnetic induction. The law of electromagnetic induction is also used e=W*-dΦ/dt.
