the intermediate frequency melting furnace in BF preparation

1. Inspect the lining. When the lining thickness (excluding asbestos cloth and refractory clay) is severely worn and corroded and thinned, the lining must be repaired and the lining must be re-knotted.

2. Check the lining for cracks. When the longitudinal crack width exceeds 3 mm , fill the lining material for repair; if there is a transverse crack running through the entire circumference, the lining cannot be used.

3. Ensure that the cooling water of all pipes is unblocked. If you find that a pipe is blocked, you must try to clean it up, otherwise the consequences will be serious .

, the safety of the intermediate frequency melting furnace during the melting process

1. The operator in front of the furnace must undergo strict professional training, and the untrained personnel must not go to the furnace for operation.

2. It is strictly forbidden to add a moist charge to melt . If there is no dry material, it must be dried before it can be put into the furnace.

3. Feed each time evenly. The chip material should be placed on the residual molten iron after the furnace is released.

4. It is strictly forbidden to add a closed tubular or hollow charge to prevent the gas from expanding and causing an explosion.

5. Whenever the material is fed, the second feed must be re-charged on the basis that the previous feed has not been completely melted. To prevent the added charge from splashing the solution.

6. If the rust or the sand with more sand, or when adding too much cold material at a time, it is easy to produce a bridge phenomenon, should be checked frequently to avoid the phenomenon of bridge .

7. Avoid violent mechanical shock to the lining.

8. It is strictly forbidden to connect the molten iron with a defective or wet ladle.

9. It is strictly forbidden to operate without cooling water.

10. The furnace structure should be reliably grounded.

11. Do not operate without normal electrical safety interlock protection.

12. In the process of charging, sampling, adding alloys, measuring temperature, slag, etc., if it is necessary to carry out the power supply, appropriate safety measures should be taken. Such as: wearing insulated shoes, with asbestos gloves, wearing insulation, with protective glasses and platform pad insulation.

13. To avoid the temperature of the molten iron from exceeding the required value, the molten iron with too high temperature will greatly reduce the service life of the lining.

14. Always check (at least once a week) whether the hydraulic hose is damaged, leaking or aging. If it is damaged or oily, it should be disposed or replaced in time.

15. Always check if the oil level of the fuel tank is normal. When the oil quantity is insufficient, it should be replenished in case of emergency.

A. P. Keep the hydraulic oil clean and replace it once a year.
