What are the safety technical operating procedures for furnace operators of medium-frequency furnaces?
Sep 13,2020
Article 1: Operators of medium-frequency furnaces must be thoroughly familiar with the performance and structural principles of medium-frequency furnaces and comply with the relevant provisions of this regulation. They may only begin operating the furnace after completing the required training and passing the assessment.
Article 2: The relevant regulations on safe electricity usage must be strictly observed.
Article 3: Personal protective equipment must be worn correctly as required.
II. Preparations Before Operation
4. Carefully inspect the electrical components, mechanical rotating mechanisms, water-cooling circulation system, and burner assembly, and ensure that they are all in good condition.
Article 5: The backup water tank must be filled with water, and it must be ensured that there is sufficient cooling water for the furnace ring in the event of a power outage.
Article 6: Inspect and ensure that the insulating platform (furnace platform board) is secure, dry, and clean.
Article 7: Inspect and ensure that the feeding path is unobstructed.
Article 8: Carefully inspect the condition of the furnace lining and promptly address any potential hazards to ensure that the furnace lining meets the safety operating requirements.
III. Operation and Precautions
Article 14: During operation, the condition of the furnace lining should be regularly inspected. Any potential hazards discovered should be promptly addressed by shutting down the furnace for repair or replacing the furnace head to resume operation.
Article 15 prohibits the delivery of furnace charge from directly in front of the furnace mouth or passing over the top of the furnace mouth onto the furnace platform.
Article 16: When adding materials, stand on an insulated platform, pay close attention to avoid getting in the way, and carefully inspect the furnace charge for sealed containers, flammable substances, explosives, oil stains, coal, and any damp furnace charge inside the furnace.
Article 17: When using the overhead crane to add materials, closely coordinate with the crane operator, securely tie down the furnace charge, and carefully lower it into the furnace slowly. Also, prevent the furnace charge from suddenly falling into the furnace.
Article 18: When the molten steel level in the furnace exceeds 1/2 of its capacity, the use of a crane to add materials into the furnace is prohibited.
Article 19: During the melting process of furnace charge, frequently stir the charge and promptly remove impurities to prevent the charge from getting stuck or the furnace opening from becoming blocked.
Article 20: When the level of molten steel in the furnace is more than 5 centimeters below the furnace platform, no further materials may be added for melting.
Article 21: When the molten steel is nearly full in the furnace, do not add large chunks of charge material.
Before Article 22 comes into effect, once the molten steel has reached a sufficiently high temperature, add the ore in batches. When adding ore, stand to the side and be careful to dodge any splashes to prevent injury from the molten steel. In Article 23, when removing slag, never use metal pipes or damp tools. In Article 24, when tapping the steel, ensure that the tapping spout, slag pit, and surrounding ground are dry and clean, and keep the passageways clear.
Article 25: During steel tapping, close coordination with the crane operator and the caster is essential. The tilting of the furnace should be slow, while the return of the furnace to its original position should be swift. If the buttons or switches for tilting and returning the furnace fail to stop functioning, immediately switch off the emergency power switch to ensure safety.
Article 26: If the crane malfunctions during operation and cannot be stopped, immediately turn off the crane’s emergency power switch, troubleshoot the issue, and confirm that there are no safety hazards before resuming use.
Article 27: When the medium-frequency furnace malfunctions, immediately stop the machine and address the issue promptly. If the problem cannot be resolved, promptly report it to the on-duty personnel. Article 28: After tapping the steel, carefully inspect whether the furnace wall can continue to be used. Article 29: When rebuilding the furnace, the furnace bottom and walls must be lined to the specified thickness as required. It is strictly prohibited to build a spare furnace lining while the medium-frequency furnace is in operation. After rebuilding the furnace, carefully check whether the furnace hearth ring is making contact with any other components.
Article 30: During the furnace drying process, follow the prescribed procedures strictly. Do not arbitrarily alter the materials used for drying or shorten the drying time. Article 31: After finishing work, carefully complete the production records and ensure a clean and well-maintained environment.
