Common problems and solutions of precision rolling mills:
Abnormal phenomenon: strip rolling mill vibration, slip
cause:

1. Precision Rolling mill roll system, motor failure

2. Friction change

3. Excessive lubrication
   Method of exclusion:

4. Check the roller drive system and motor system.

5. Check the emulsion concentration and saponification value (miscellaneous oil content)

6. Check the surface roughness of the rollers

7. Control the processing rate

8. Check the surface condition of raw materials
   Abnormal phenomenon: board surface oil, scratches, sticking board, sticking roller, bursting roller
   cause:

9. Insufficient lubrication

10. The roll is partially scratched, fluffed or foreign matter enters

11. The roll is fatigued or not preheated

12. The temperature of the emulsion is too high and the local heat is generated

13. Poor plate shape and excessive local stress
    Method of exclusion:

14. Check the emulsion concentration, saponification value, PH value, iron, ash content and temperature

15. Check or replace the rolls and remove foreign objects.

16. Preheating rolls, quantitative replacement

17. Check the emulsion nozzle, the pressure

18. Control panel type
    Abnormal phenomenon: bad shape (medium wave)
    cause:

19. Insufficient cooling

20. Poor roll design and poor stringing

21. The rolling force is too small
    Method of exclusion:

22. Check the emulsion temperature and cooling effect

23. The roll shape design is suitable to reduce the pull out of the string roller

24. Increase the rolling force
    Abnormal phenomenon: bad shape (rib wave)
    cause:

25. Uneven cooling, local heating

26. Poor roll design and poor stringing

27. The rolling force is too small and the tension is too small
    Method of exclusion:

28. Check the emulsion nozzle, pressure, etc.

29. The roll shape design is suitable to reduce the pull out of the string roller

30. Increase the rolling force and increase the tension
    Abnormal phenomenon: bad shape (edge wave)
    cause:

31. Poor roll design and poor stringing

32. The rolling force is too large and the speed is too slow

33. Excessive cooling
    Method of exclusion:

34. The roll shape design is appropriate to increase the advance of the series of rolls

35. The rolling force decreases and the speed increases

36. Check the temperature of the emulsion
    Abnormal phenomenon: bad shape (rib wave + side wave)
    cause:

37. Strip deviation

38. Partial heating of the roll

39. The pressure deviation is too large
    Method of exclusion:

40. Correction strip center

41. Check the cooling effect of the emulsion

42. Check the roll surface or replace the roll

43. Adjust the pressure deviation
