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.
