1.Check the rolling mill daily for any strange noise, spot check the coupling for any strange noise and heating phenomenon, whether the coupling bolt is loose.
2.Check whether there is a large amount of oil leakage signs at the seal of pre-finish rolling transmission box and connection flange, slight leakage is allowed, but should be wiped clean, listen to whether there is a strange noise from the gears or bearings.
3.Check whether the oil and gas lubrication PU pipe of the pre-finishing roll box panel falls off to ensure that the lubrication points are in good lubrication condition.
4.Check every day whether there is oil leakage from the combination surface of roller box and cone box, if there is thin oil leakage, the double lip and O-ring seal should be replaced by optional machine.
5.Every day should check the gear box, try to listen to the gear and bearing for any strange sound, check the temperature of the box at the bearing.
6.Every shift inspection of lubricating oil pressure, flow, cooling water pressure, shall not be lower than the specified value.
7.For the finishing rolling unit 10 mills to be measured twice a shift sub-vibration, the required vibration value ≤ 4.5 mm / s, such as greater than this standard, need to pay attention to observe its development trend and promptly inform the shift manager. If the vibration remains stable in a higher range of vibration values, production can continue to maintain.
8.If there is a fault alarm of the finishing rolling unit during the production, the maintenance personnel should check carefully and confirm before agreeing to continue to turn.
9.If the roller box parameters are found to have seriously exceeded the standard during the inspection, the roller box should be replaced immediately.
10.Check daily whether the solenoid valve of the pinch feed roller is intact and whether the air and water lines are smooth, and deal with the problems found in time.
11.Check the wear of the inlet conduit of the spitting machine every day, and replace it in time when the wear is serious.
12.Check the vibration of the wire rolling mill during operation, if the vibration is found to increase, it should be stopped to check whether the installation of the spitting tube is secure, check whether the bolt connection between the wire plant spitting machine and the hollow shaft is tight.
13.Regularly check the wear of the live set of rollers and the smoothness of the oil and gas lubrication of the rollers on a daily basis, and promptly replace the maintenance for the specific situation.
