How to use medium frequency electric furnace to save electricity?

The power consumption in the application of medium frequency electric furnace is very large, so many enterprises will find ways to reduce power consumption when using it. The following section introduces the method of reducing power consumption of medium frequency electric furnace.

The reasonable smelting process shall be prepared according to the metallurgical characteristics of the medium frequency induction furnace. The charging, temperature control, addition of alloy, carburetor, slag making agent at different temperatures, and tapping temperature shall be strictly controlled. The shortest smelting time, the smallest alloy burning loss and oxidation shall be used to control and stabilize the metallographic structure and improve the quality of rolls.

1. Equipment selection

Select the medium frequency furnace that is suitable for matching the production capacity with the molding line, and select the medium frequency furnace that is safe, environmentally friendly, efficient, energy-saving and stable for Leko industry.

2. Reasonable ingredients

Scientifically manage and use the furnace charge to ensure that the main chemical components meet the requirements and the content of harmful impurities is as low as possible, so as to avoid delaying the smelting time due to composition adjustment, and avoid scrapping due to unqualified composition.

During the feeding process, the metal shall be kept as dense as possible to fill the whole furnace cavity, so as to ensure the maximum utilization of thermal efficiency and improve the melting efficiency.

3. Reasonable smelting operation

Optimize the feeding sequence, feed in time and operate carefully to avoid bridging the furnace charge.

(Reasons for bridging: too much charging at one time, the upper furnace charge is stacked too tightly, the furnace charge is stuck and overhead; the furnace charge structure is unreasonable, the upper material block is small, the melting point is high, the lower material block is large, and the melting point is low; the furnace wall is not smooth, which is unfavorable to the smooth running of the furnace charge. Consequences of bridging the furnace charge: the temperature of the lower molten pool is constantly rising, forming a high temperature and high pressure atmosphere in the furnace, and the metal liquid severely erodes the lining refractory material, even leading to local metal liquid leakage of the furnace body, which causes The cooling water enters the metal molten pool and causes a big explosion.)

4. Reasonably control tapping temperature

For smelting, the temperature shall be raised in a short time before pouring to meet the process requirements, while the molten iron shall be kept at a lower temperature for the rest of the time, which can reduce the erosion of high-temperature molten iron on the furnace lining, extend the service life of the furnace lining, and reduce power consumption.
