Cold rolling mill plate handling, difficult problems and four-high reversible mill tension ratio information and characteristics and advantages

【Summary description】

????

The roll in the cold rolling mill is the key component of the rolling mill. Therefore, the roll is important for the selection of the motor of the rolling mill. The work rolls of cold rolling mills are generally divided into two types: arc rolls and friendship rolls. If it is used as a work roll, it is more suitable for an arc roll. For lower work rolls, flat rolls are more suitable. Therefore, generally speaking, people choose according to this criterion.

 

From the point of view of its special tools, cold rolling mill flatness control is more widely used at this stage, such as the leveling of the middle roll and the skew of the roll gap. In addition, if there is a bending roll system on the cold rolling mill, the bending roll system software can be adjusted to maintain the operation. Common product quality problems of aluminum strip cold rolling mills include wave patterns, patterns, patterns, vertical bright relative paths, roller bearings, and imprints. Therefore, people should reasonably solve this practical problem and take effective measures to prevent this problem from reappearing.

 

During the whole process of cold rolling, the four-high reversible cold rolling mill generally has a supporting force ratio of 1:1, that is, the supporting force is the same, but it can be adjusted appropriately, how to adjust, and how much it is, depending on the application regulations and equipment of the machine. The quality of the product is all determined by them. In the four-high reversible cold rolling mill, the supporting force is used to accurately measure the supporting force to obtain the ratio. Therefore, this is measured according to a specific value and has no relation to the preset value. In addition, it can be regarded as the work pressure caused on the supporting force test roll, so the use value enterprise is a cow. The key difference between a four-high reversible cold rolling mill and a four-high cold rolling mill is that the cold rolling of the four-high reversible cold rolling mill can be carried out repeatedly without a fixed orientation. Generally, a four-high cold rolling mill has only one orientation for cold rolling. Therefore, the structure of the two cold rolling mills and the heat resistance are different from each other.

 

The four-high reversible cold rolling mill is one of the four-high cold rolling mills from a technical perspective. The four-high cold rolling mill belongs to the technical industry of cold rolling mills, so the four-high reversible cold rolling mill also belongs to the technical industry of cold rolling mills. . Like the general four-high cold rolling mill, it is also four-high, two supporting point rolls and two working rolls.
