Car Bottom Furnace Operation Procedures

Feb 10, 2025

Car Bottom Furnace Operation Procedures

1. Operators must understand the following points

A. The structure and performance of the car bottom furnace and its auxiliary equipment.

B. The layout of power distribution systems, control systems, and the location of safety devices.

C.Operating techniques and safety operation procedures.

2. Pre operation preparation work inspection

A. Whether the power supply of the car bottom furnace is normal, and whether there are any phase breaks, short circuits, or exposed wires.

B. Check if the contact at the grounding device wiring is good.

C. Inspect the heating elements for any damage, ensure all connections are in good contact, and check if they come into contact with the furnace body or cover shell.

D. Check if there are any abnormal phenomena in the temperature control system.

E. Check if the car bottom furnace door lifting and trolley entry and exit operation are normal.

3. Workpieces containing corrosive, volatile, and explosive gases are strictly prohibited from entering the car bottom furnace for processing, in order to avoid affecting the service life of heating elements and refractory materials and causing accidents such as explosions.

Car Bottom Furnace Operation Procedures

4. The trolley furnace must not operate at excessive temperatures, otherwise it will shorten the service life of the furnace.

5. The workpieces should be evenly stacked, with a distance of about 100-150mm from the heating element.

6. Workpieces with excessive oxide scale need to be removed before entering the furnace, and can be brushed off with a wire brush.

7. Rough handling is strictly prohibited, and workpieces should be handled gently to avoid impact.

8. When using the trolley furnace, the operator must not leave the post without authorization and must always pay attention to whether the working condition of the trolley furnace is normal,

9. When loading and unloading workpieces in the trolley furnace, the power supply of the heating element must be cut off first to ensure the safety of the operator.

10. The oxides in the furnace (including those under the trolley furnace wire) should be cleaned regularly, at least once a week or once every five batches. Compressed air can be used to clean beneath the bottom plate of furnace.

11. Regularly check the usage of heating elements. After short-term use, the heating element must not bend or collide. If it has not been severely corroded and broken, the same material as the electric furnace wire (or the electric furnace wire itself) can be used as the welding rod, and acetylene gas can be used for heating and welding. The welding rod consists of a 50% mixture of dolomite powder. If the heating element is severely corroded and unusable, it should be replaced.

12. Regularly verify the deviation of instruments and thermocouples to prevent incorrect temperature measurement caused by errors in instruments and thermocouples, which may affect product quality.

13. Once used, resistance wires should not be collided with or bent to avoid breakage.

14. The electric motor of the car bottom trolley furnace needs to be inspected regularly, lubricating oil should be added, and attention should be paid to safety during use.
