However, there are many problems that may be encountered when smelting ferrosilicon. The following mainly introduces that when smelting ferrosilicon, the electrode should not be inserted deeply when there is a serious shortage of material in the furnace.
If the material surface is high, the electrode will be shallow when inserted into the furnace material. Now it is pointed out that there is a serious shortage of materials in the furnace and the electrodes should not be inserted deeply. The two are not contradictory. There are two main factors that affect the electrode insertion depth: one is the contact surface between the charge and the electrode. As the contact surface increases, the passing current increases. In order to maintain the rated current, the electrode must be raised.
The material surface is high and the electrode is inserted shallowly into the material, which exactly illustrates this situation. The second is the conductivity of the charge. The stronger the conductivity, the shallower the insertion depth of the motor, that is, the electrode should not be inserted deeply. There are many factors that affect the conductivity of the charge, such as the temperature of the charge and the properties of the charge itself. The higher the temperature of the charge, the stronger its electrical conductivity, and the electrode should not be inserted deeply. There is a serious shortage of materials in the furnace and the electrodes should not be inserted deeply, which illustrates this situation.
In addition, before shutting down the furnace, the material level should be lowered and no material should be added into the furnace; sometimes during the smelting process, due to a malfunction of the feeding system, the material cannot be added or only very little material is added. People often call this situation "relying on the material surface" or "empty". "", you will see that the electrode should not be inserted deeply and has an upward trend. This is because no materials are added to the furnace or too little is added, and the amount of materials in the furnace gradually decreases with smelting. At this time, the furnace materials
As the temperature gradually increases, its resistance decreases and its conductivity increases, so the electrode should not be inserted deeply.
