Cold rolling mill maintenance and safety technology

Cold rolling mill maintenance and safety technology

Even a perfect mechanical device also requires correct operation, use, and meticulous maintenance and maintenance to ensure long-term reliable operation of the equipment. Therefore, it is very important to attach importance to the safety technologies such as maintenance and maintenance.

1 Designated maintenance manager

If the responsible person for operation and maintenance of the equipment is not clear, or if maintenance and maintenance are not considered important, equipment maintenance is still good, etc., this will reduce the operational reliability of the equipment and shorten its service life. There are even catastrophic consequences for small things.

Please specify the person responsible for operating and maintaining the POR and specify the responsibility.

2 Create a working diary

The person in charge of operation and maintenance should record the daily operation, maintenance and maintenance of the cold rolling mill and carefully fill in the operating diary as management data.

The items that need to be recorded in the operating diary are: operation, maintenance, faults, and so on.

Strengthening the management of maintenance and maintenance can prolong the service life of the POR and reduce the production cost.

3 Periodic inspections, repairs

The equipment is important on the production line and cannot be shut down. Even if a small anomaly is found, it will have to be “ill” to operate, which will inevitably accelerate the loss of the abnormal part; there are also some places that are not visible to the naked eye during operation, or may be inaccessible by the inspection personnel during operation. There are hidden dangers; in addition, some parts of the POR have their own service life, and the lubricating oil should be replaced regularly. To accomplish this kind of operation, the POR needs to be shut down for maintenance. Therefore, in the preparation of the production plan, it is necessary to consider in advance the issue of regular shutdown of the POR, which is extremely important for reducing accidents and maintaining normal production operations. The time for regular maintenance is set according to actual conditions. Normally, except for daily inspections, inspections can be divided into small, medium, and overhauls.

4 General considerations

Please pay attention to abnormal sound, vibration and heat

The causes of the above abnormalities are usually loose bolts, alignment damage, bearing damage, oil cut-off, biting debris, etc. If you continue to operate without paying attention, you may cause a major accident.

To prevent major accidents through early diagnosis, special attention must be paid to abnormal noise, heat, and vibration after starting.

Please observe the ammeter of the motor and other instruments

The motor current exceeds the normal value mainly due to mechanical abnormality, overload, power supply voltage drop, or abnormality in the motor itself. Therefore, it is very important to confirm the motor current. Especially after starting, please observe the condition of the current meter for a while. If it exceeds the normal value, check the parts carefully. The same is true for other instruments.

5 Safety Precautions

Regardless of whether the equipment is working or not, no one can stand within the safety rails around the equipment. To avoid accidents.

Please pay attention to fire prevention.
