Nowadays, precision casting is a common production method in the machining process. If the operation is not standard, the casting will be affected by other interference and quality. What should be paid attention to in the operation?


1. Remove the obstacles at the entrance and exit as well as the plant area.


2. It is necessary to check whether the ladle is dried, whether the ladle bottom, the ladle ear and the ladle rod are safe and stable, and whether the rotating place is sensitive. It is not allowed to use the equipment that has not been dried.


3. Tools to be contacted with molten iron must be heated in advance, otherwise they cannot be used.


4. Molten iron shall not exceed 80% of the volume of the ladle, and it shall be stable when moving to avoid scalding.


5. Before using the crane for operation, check whether the hook is safe in advance. During operation, special personnel shall be assigned for supervision. No personnel shall appear after passing the route.


6. The casting shall be precise and stable, and molten iron shall not be poured from the riser to the sand box.


7. When the molten iron is poured into the sand mold, it is necessary to ignite the industrial waste gas discharged from the air outlet, riser and gap in time to prevent the toxic gas and molten iron splashing from hurting people.


8. Excess hot metal must be poured into the prepared sand pit or iron film. It cannot be poured in other places to avoid explosion and personal injury. In case of splashing on the road during transportation, clean it immediately after dry consolidation.


9. Before use, all equipment shall be inspected to prevent potential safety hazards and cleaned immediately after use.
