What are the characteristics of electric arc furnaces? Electric arc steelmaking furnaces use electricity as their main energy source. Electric energy is discharged through graphite electrodes and furnace materials to generate high temperatures of up to 2000-6000 ℃, melting scrap steel raw materials through arc radiation, temperature convection, and heat conduction. During most of the time when the furnace charge is melted, the high-temperature heat source is surrounded by the furnace charge, and the heat loss caused by high-temperature exhaust gas is relatively small, so the thermal efficiency is higher than other steelmaking equipment such as converters. In addition, electric heating is easy to precisely control the furnace temperature and can be operated under any conditions such as oxidizing or reducing atmosphere, atmospheric pressure or vacuum according to process requirements. The electric arc furnace steelmaking process has a short process flow, simple equipment, easy operation, relatively easy pollution control, low construction investment, small footprint, and does not require relying on complex ironmaking systems like converter steelmaking. Electric arc furnace steelmaking has strong adaptability to furnace materials. It mainly uses scrap steel as the main raw material, but can also use solid and liquid iron containing raw materials such as molten iron (blast furnace or iron smelting furnace molten iron), sponge iron (DRI) or hot pressing block (HBI), pig iron block, etc. Due to the controllable atmosphere inside the electric arc furnace steelmaking furnace, the operation of adjusting or replacing slag is relatively easy, and complex process operations such as melting, decarbonization, dephosphorization, degassing, inclusions removal, temperature control, and composition adjustment (alloying) can be completed in the same operating system. Electric arc furnace steelmaking can produce intermittently and flexibly switch production varieties within a certain range. In addition, modern electric arc furnaces can also use a large amount of auxiliary energy, such as injecting heavy (light) oil, coal powder, natural gas, etc. Therefore, the electric arc furnace steelmaking process has strong adaptability, flexible operation, and wide application. Electric arc furnaces can not only smelt steel with low phosphorus, sulfur, and oxygen content, but also alloy various elements (including easily oxidizable elements such as lead, boron, vanadium, titanium, and rare earths) to produce various types of steel and alloy steels, such as ball bearing steel, stainless acid resistant steel, tool steel, electrical steel, heat-resistant steel, magnetic materials, and special alloys. Alright, the above is the introduction of relevant information about electric arc furnace steelmaking.

Precautions for operating the ladle refining furnace! What are the precautions for operating a ladle refining furnace? Today, we invite the arc furnace manufacturer to introduce them to you! 1. Before starting work, check whether the interlocking protection device and travel switch of the steel ladle are safe and reliable. 2. Check the vacuum system, blowing oxygen, blowing hydrogen, insulation, heating, feeding and other mechanical parts, and confirm their safety and reliability before starting the vehicle. 3. Check if the sample spoon and mold are kept dry. 4. Check if the workstation equipment used is functional. 5. Contact the power supply unit and vacuum control room according to regulations. Before driving, it is necessary to ring the bell or activate other safety signals. 7. Perform high-voltage power transmission and vacuum degassing according to the program. 8. When starting the steel ladle, it is necessary to check the track and remove obstacles at all times. 9. It is strictly prohibited to pass under high-voltage lines after power transmission. 10. When connecting or unloading pressure pipeline joints, the valve must be closed before operation. 11. When using oxygen, it is strictly prohibited to hold it in front of the card head and wear oily gloves for operation. 12. After sampling, the remaining molten steel should be poured into a dry place. 13. When releasing the vacuum, no personnel are allowed to approach the air supply pipe opening. 14. For inspection and maintenance, when climbing onto the heating bridge for operation, the high-voltage key must be removed, the high-voltage power supply must be cut off, and the operator must bring their own key. 15. When changing electrodes, a dedicated person should be assigned to command. The lifting ring and hook should be connected with a steel wire rope, and the hook safety should be closed. It is strictly prohibited to lift and replace all three phases at the same time. 16. No objects shall be stacked on the furnace cover or bridge, and it is strictly prohibited to throw objects up or down while working on the bridge. Alright, the above is the introduction to the operation of the ladle refining furnace.
