What are the factors that affect the energy consumption of the medium frequency furnace?
The power density configuration of the induction furnace.
The configuration is high, the melting speed is fast, and the energy saving effect is good. Whether the electric furnace can maintain high power and continuously send power to the furnace will affect the level of energy consumption; the messy arrangement of the power cord of the medium frequency furnace will affect the processing capacity of the power supply, resulting in unstable power, low power conversion efficiency, and energy consumption .
The cleanliness of the surface of the charge, if there are 5% impurities, it will consume 5% of the electric energy to melt these impurities, and it will also affect the life of the furnace lining; whether the length of the charge block is appropriate will affect the electric efficiency and melting quality of the electric furnace, generally 200～ 300mm block size is appropriate;
The use of a suitable crucible can increase the melting rate. The quartz crucible is resistant to high temperatures and is used with an medium frequency furnace. The metal material in the crucible generates heat through induction heating, which can reduce the consumption of heat transfer.
- Improper operation causes high energy consumption
The molten metal is overheated and the furnace is discharged continuously. Not only is it unsafe, it is also wrong in terms of energy consumption and melting process. Generally, electric furnace inductors are divided into upper and lower parts. When the molten metal level in the furnace is lower than half of the upper inductor, due to the change of resistance, the upper inductor no longer has induced current to pass, and all are concentrated in the lower inductor, so that the lower molten metal Overheating, scouring the furnace wall, the life of the furnace lining drops sharply
