Analysis of the influence factors of rolling the wall and the corresponding countermeasures.

Rolling wall refers to the wear and failure of the roll surface due to the interaction between the roll and the material in industrial production. The existence of the mill wall directly affects the production efficiency and product quality of the mill. This paper will analyze the influence factors of rolling the wall, and put forward the corresponding countermeasures.

The selection of 1. materials and quality materials play a decisive role in the formation and life of the rolling wall. The selection of materials with higher hardness can reduce the formation of the rolling wall and increase its service life. In addition, the quality of the material will also affect the formation and development of the mill wall. If the quality of the material is not up to standard, containing undesirable impurities or defects, it is easy to cause the formation of the rolling wall. Therefore, it is very important to strengthen the quality control of materials and select suitable materials to reduce the formation of rolling wall.

Countermeasures: to strengthen the selection of materials and quality control, give priority to the selection of higher hardness, better quality materials. At the same time, improve the material processing technology, reduce the existence of impurities and defects.

2. heat treatment process heat treatment process directly affects the hardness and toughness of the material, and then affects the formation and development of the rolling wall. If the heat treatment process is not appropriate, it may lead to uneven hardness or insufficient toughness of the material, which is easy to form or aggravate the formation of the rolling wall. Therefore, optimizing the heat treatment process to ensure that the hardness and toughness of the material meet the requirements is of great significance to reduce the formation of the rolling wall.

Countermeasures: by optimizing the heat treatment process, to ensure that the hardness and toughness of the material is uniform, to avoid insufficient hardness or uneven situation.

The quality of the 3. roll As an important part of the rolling mill, the quality of the roll directly affects the formation and development of the rolling wall. If the material of the roll is not properly selected or the manufacturing process is poor, it is easy to cause the wear of the roll surface to increase and form the rolling wall. Therefore, to improve the quality of the roll, select the appropriate material and optimize the manufacturing process to reduce the formation of the mill wall has a vital role.

Countermeasures: Strengthen the quality control of the roll to ensure that the material and manufacturing process of the roll meet the requirements. At the same time, regular maintenance of the roll, timely replacement of the damaged roll, reduce the wear and tear of the roll.

4. lubrication and cooling system equipment and the use of lubrication and cooling system equipment and the use of rolling wall formation and development plays an important role. If the equipment of the lubrication and cooling system is not good or used improperly, the surface temperature of the roll is too high or the lubrication is insufficient, which is easy to form or aggravate the rolling wall. Therefore, the optimization of lubrication and cooling system equipment, rational use of lubricants and coolants, to reduce the formation of the mill wall is essential.

Countermeasures: Optimize the equipment of the lubrication and cooling system to ensure its normal operation and stability. At the same time, reasonable selection of lubricants and coolants, and control the amount of use to ensure that the surface temperature and lubrication of the roll are in good condition.
