Ferrosilicon is an important metallurgical raw material and is widely used in steel, casting, chemical and other fields. In the production process of ferrosilicon, electrode paste is an indispensable part. During the smelting process, the use of ferrosilicon electrode paste is very important. First, the quality of the electrode paste directly affects the efficiency and cost of smelting; second, the selection of the electrode paste will also affect the quality of ferrosilicon. Rongxing ferrosilicon electrode paste is a conductive material made of raw materials such as anthracite, coke and coal asphalt. As the key raw material for self-baking electrodes, the ferrosilicon electrode paste is gradually sintered and molded at high temperatures to form a conductor that can withstand extremely high currents. Without ferrosilicon electrode paste, the ore furnace will not be able to operate normally, and there is no way to talk about the production of ferrosilicon alloys. In practical applications, workers fill the ferrosilicon electrode paste into the electrode shell and calcinate it by relying on the high temperature in the furnace. This process requires the ferrosilicon electrode paste to have stable physical and chemical properties. Each batch of ferrosilicon electrode paste must undergo strict inspection to ensure that its resistivity, compressive strength and other indicators meet the requirements. It is these characteristics that make ferrosilicon electrode paste the core material for ferrosilicon production.

At present, when producing ferrosilicon alloys in the mine furnace, standard ferrosilicon electrode pastes are usually used. With the widespread application of large-capacity ore heat furnaces and sealed electric furnaces, the number of large-scale electric furnaces has continued to increase, and the output of ferroalloys has increased significantly. Many ferrosilicon alloy ore heat furnaces have gradually switched to sealed electrode pastes. In order to ensure that the self-baked electrode can be sintered in the early stage, there are also some ferrosilicon alloy manufacturers, especially electric furnace ferrosilicon manufacturers. According to the needs of the factory, they usually choose high-standard sealed electrode paste that is more suitable for them. Among them, the main focus is on high-standard ferrosilicon electrode paste being easy to bake, stable performance and quality, which can ensure the sintering quality of the electrode and prevent soft short circuits, hard breaks, and turnovers.

A ferrosillicon alloy factory has been in operation for 7 months, and there have been 22 accidents of paste leakage and hard breakage, resulting in 48 severe electrode shorts. Later, after the above-mentioned ferrosillicon factory switched to Rongxing carbon high-standard ferrosillicon electrode paste, there was only one non-electrode paste quality failure accident in 8 months. Users are satisfied with the quality of Rongxing Carbon's ferrosillicon electrode paste.
