Rolling Mill Lead Operator Job Responsibilities

I. Job Responsibilities

Responsible for scheduling and controlling the rolling steel production line.

2. Responsible for setting and adjusting the rolling process parameters and cooling process parameters in the main control room.

3. Responsible for quality and production records.

II. Procedures

Strictly enforce the operation card system; no operation card, no power to any electrical equipment.

2. The main control room is a critical area; unauthorized personnel are prohibited from entering. The position must not be delegated to others for operation.

3. Upon joining the position, focus on coordinating the work of various processes, always be attentive to the on-site conditions, and have the authority to immediately stop the operation in the event of a major emergency.

During equipment maintenance or shutdown, the control room must be staffed. All switches must not be tampered with at will.

5. Operators must continuously monitor the positions of the on-site adjusters and maintenance inspectors during the production process to prevent any unexpected accidents.

Upon receiving notification that all processes are normal, the "Request for Steel" signal may be issued.

Operators should take different measures based on the fault signals issued from different areas.

8. In the event of a steel pile-up, immediately activate the flying shear to break it apart, and notify the heating furnace to stop steel production. Simultaneously, cut off the shear and shut down the furnace discharge roller.

III. Key Operations

1. Upon taking over, thoroughly inspect the nozzles and tubes for blockages, verify that water pressure and flow are normal, check that all valves open and close smoothly and quickly, and ensure that the reverse pressure meets requirements.

2. Parameter Settings

Different steel grades require various cooling processes, necessitating the adjustment of the following control parameters based on the steel type:

3. Number of Water Tanks Used

4. Flow and pressure of water-cooled reverse and positive nozzles

5. Spinning Temperature

6. Speeds of all rolling mills

7. Coiling Temperature

8. Test Run Inspection: After setting all parameters, a driving test must be conducted to verify if the actual parameters meet the process requirements. Any discrepancies are manually adjusted. Once all parameters meet the process requirements, report to the main control station and commence rolling production.

During the normal production process, it is essential to frequently check the equipment's operating status, monitor parameter changes, and make adjustments as needed, strictly controlling the water, air volume, and silk extrusion temperature.

Ensure regular inspections of parts such as guide slots and spooling tubes for wear and replace them promptly.

Pay attention to controlling the size and shape of the spool, and adjust promptly to prevent tangled threads.
