How to use medium frequency electric furnace to save electricity?
Compared with traditional equipment, medium frequency electric furnace has the characteristics of domestic leading in energy saving rate, small impact on power grid, high melting efficiency, uniform solution temperature, small oxidation loss, uniform metal composition, simple temperature control and good heat preservation.
The power consumption of medium frequency electric furnace is very large, so many enterprises will find ways to reduce power consumption when using it. The following small series introduces the methods of reducing power consumption of medium frequency electric furnace.
The rationality of the layout. On the premise of ensuring the reasonable operation of workers, the overall layout of the electric furnace should try to reduce the space layout as much as possible, so that all the connection lines will be shortened, and then the heat and electricity will be reduced, so as to save electricity on the main road.
2. The data used should be as large as possible to ensure the smooth movement of the current, so as to prevent the copper bar from being too small and forming heat, and then take away part of the electricity.
3. The workers of medium frequency electric furnace company should be diligent, constantly feed and assist in mixing steel, advance smelting speed and save power consumption.
4. The technical content of medium frequency furnace is not well recognized by the manufacturers. Although the technology of medium frequency furnace is relatively mature, each company still has its own specific advantages. Therefore, it is advocated that manufacturers should try to select large manufacturers to cooperate when buying electric furnace, so as to save power consumption.

Causes of abnormal starting of medium frequency electric furnace
What is the cause of abnormal start of medium frequency electric furnace?Lack of phase of rectifier: the fault is that the sound is abnormal during operation, the larger output voltage rises below the rated value, and the abnormal noise announced by the power cabinet is becoming larger and l
