The company's main products include the electric slag furnace series, which includes ordinary electric slag remelting furnaces, electric slag melting furnaces, atmosphere protected electric slag furnaces, and so on. Our company has modern factories and advanced process equipment, complete testing equipment, strong technical strength, stable and reliable product quality, and is popular all over the country, receiving high praise from users. At the same time, our company also maintains good relationships with experts and professors from Shanghai Jiao Tong University, Southeast University, Chongqing University of Science and Technology, China Iron and Steel Research Institute, Shanghai Iron and Steel Research Institute, Guangxi Metallurgical Research Institute, etc., to develop and innovate products. Today, we will introduce the operating precautions for electric slag furnaces. Let's take a look at the information provided by the electric slag furnace manufacturer:

1. Before starting the electric slag furnace melting process, test the operation of the furnace to ensure that it operates normally during the melting process. Check if the transformer is operating normally and if the gas pressure is normal.

2. Operate the power cabinet in the operating room, pay attention to the normal three-phase voltage between 380 volts and 420 volts, and turn off the control power required during the smelting process,

3. The control panel has high-voltage off and high-voltage on buttons, as well as high-voltage emergency trip buttons. When the high voltage is closed, pay attention to placing the isolation switch in the middle position (i.e. all six isolation switches are open), and check whether the secondary voltmeter of the transformer displays to determine whether the high voltage has been sent out.

4. When using slag, the distance between the three-phase electrodes should be adjusted first to confirm that there is no short circuit between the three phases; In order to adjust the position of the ingot trolley, three electrodes are placed in the center of the crystallizer to better balance the three-phase current.

5. After the high voltage is turned off, the operator should pay attention to external control when cutting the electrode group, so that the front desk personnel can prepare for melting and lower the electrode of the working group to near the liquid level. Afterwards, the operator enters the internal control of the cross arm to be processed, enters the isolation group to be processed, and slowly descends the arc. (Note: After the high voltage is turned off, the isolation will not be cut off. There will be an alarm prompt after 20 seconds. When the isolation cut-off is selected, the alarm will automatically stop).

6. When replacing the electrode group, the operator should lift the electrode group until there is no current display before cutting off the external control and having the front desk staff replace the electrode. (Note: During this period, an alarm will be issued to remind the operator to isolate the uncut state. After the pre melting furnace staff is ready, the operator should enter the selected cross arm isolation area and then perform electrode dispersion.)
