How to deal with specific problems in rolling mill applications?
At present, new model CRM wire rolling mill equipment is an essential component in strip processing. Its road roller can improve the movement of the steel strip and the flatness of the cold rolls, thereby improving the efficiency of the use of the rolls, thereby increasing the service life of the rolls. However, in specific applications, the roller equipment is generally equipped with vicious oil seepage and pipe blocking compensation oil. At present, the reasons for common failures are closely combined with the basic principles of actual operation.
Due to the actual operation of the radial connection of the rolls, the steel joints are generated according to the actual operation of the rolls for maintenance, and the position sensor is installed on the winding roll to accurately measure the actual operation of the left and right rolls, which can improve the appearance of the strip. When it [...]

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 [...]

How to better control the use of rolling mill equipment?
Practical thin wire rolling mill, which can improve the quality of the steel plate finish, it can reduce the friction of the bearing, increase its service life, and effectively dissipate the heat of the gear, it can also reduce the weight of the protective casing, while improving the resistance and sound insulation of the protective casing , and provide a better perspective of use, in the automatic high-precision wire and strip cold rolling thickness control technology, foreign countries have reached a high level, how to control the use of equipment?
Nowadays, some achievements have been made in this field in China, but there is still a gap compared with developed countries. Therefore, professional equipment manufacturers have studied the influence of the thickness of the oil film coil. According to the change of the relative thickness of the oil film, the cold compensation control rolling mill has been [...]
