Rolls for rolling mill usage specifications

Table of Contents

Improper use of rolling mill rolls may result in damage and premature failure of the rolls, increasing repair and replacement costs. Standardizing the use of rolls is of great significance for ensuring product quality, extending rolls life, improving production efficiency and reducing maintenance costs. Therefore, we must pay attention to the usage specifications of the rolls to ensure the stable and efficient operation of the rolling mill.

1. Selection

According to production needs, select rolls with appropriate specifications, materials and performance. Ensure that the load-bearing capacity, hardness, wear resistance, etc. of the rolling mill rolls meet the process requirements.

2. Installation

1. Check the integrity of the rolls for rolling mill to ensure there is no damage or cracks.

2. According to the rolling mill model and design requirements, install the rolls correctly to ensure their stable operation.

3. Adjust the distance between rollers to ensure compliance with process requirements.

3. Adjustment

1. According to product specifications and process requirements, adjust the position and angle of the rolls to ensure rolling accuracy.

2. Adjust the rotation speed and steering of the roll to meet production needs.

3. During the adjustment process, pay attention to the operation of the roller to ensure that there is no abnormal sound or vibration.

4. Maintenance

1. Regularly check the surface quality of the rolls. If wear, scratches, etc. are found, deal with or replace them in time.

2. Lubricate the roll regularly to maintain its good operating condition.

3. Regularly clean the residue on the surface of the roller to prevent it from affecting product quality.

5. Replacement

1. When the rolling mill rolls is seriously worn or damaged, it should be replaced in time.

2. When disassembling and installing the rolls, appropriate tools and methods should be used to avoid damage.

3. After replacement, the installation accuracy of the rolls should be checked to ensure its stable operation.

6.Temperature control

1. Keep the rolls temperature stable to avoid affecting product quality due to too high or too low temperature.

2. Monitor the rolls temperature, detect abnormalities in time and deal with them.

3. Take appropriate cooling measures as needed, such as using coolant or air cooling system.

7. Pressure control

1. Adjust the roller pressure to ensure the stability of product specifications and quality.

2. Monitor the rolling mill rolls pressure to prevent damage to the roller due to overload or insufficient pressure.

3. During the pressure adjustment process, pay attention to the operating status of the rolling mill to prevent equipment damage due to uneven pressure.

8. Surface quality inspection

1. Use surface inspection instruments to regularly check the surface quality of the rolls.

2. Observe whether there are cracks, peeling, pores and other defects on the surface of the roll. If found, the roller should be processed or replaced in time.

3. Regularly conduct roughness testing on the roll surface to ensure that it meets process requirements.

9. Safe operation of rolls

1. Operators should receive professional training and be familiar with the operating procedures and safety precautions of the rolling mill.

2. During operation, corresponding labor protection equipment should be worn to prevent accidental injuries.

3. It is prohibited to carry out maintenance or adjustment work while the equipment is in operation. If maintenance or adjustment is needed, stop the machine and cut off the power supply first.

4. When dealing with abnormal situations, you should stay calm, follow emergency procedures, and report to relevant departments in a timely manner.

5. Regularly inspect and maintain safety facilities to ensure their effectiveness.

6. Comply with relevant laws and regulations on production safety to ensure operational safety.

10. Storage and transportation

1. Newly purchased or repaired rolls should be stored in a dry, dust-free, and corrosive gas-free environment. When storing, it should be placed flat or supported with a bracket to avoid deformation caused by long-term stacking pressure.

2. Severe vibration and impact should be avoided during transportation to prevent roll deformation or damage.

3. Rolls with special requirements (such as high-precision rolls) should be stored and transported according to the manufacturer’s requirements.
