In the cold rolling mill, the roll is the key component of the rolling mill. Therefore, the roll is an important part of the selection of rolling mill motor. The working roll of cold rolling mill is generally divided into arc roll and friendship roll. If it is used as work roll, it is more suitable for arc roll. For lower work rolls, flat rolls are more suitable. Therefore, generally speaking, people choose according to this standard.
In terms of special tools, the shape control of cold rolling mill is more widely used at this stage, which is the horizontal movement of medium roll and the skew of roll gap. In addition, if there is a roll bending system on the cold rolling mill, the roll bending system software can be adjusted to maintain the same operation. The common product quality problems of aluminum strip cold rolling mill include wavy pattern, mode, pattern, vertical path, roller bearing and embossing. Therefore, people should reasonably solve this practical problem and take effective measures to avoid its recurrence.
In the whole process of cold rolling, the supporting force ratio of four roll reversible cold rolling mill is generally 1:1, that is, the supporting force is consistent, but it can be adjusted appropriately. How to adjust and how much depends on the application regulations of machinery and equipment and product quality, which is all decided by them. In the four roll reversible cold rolling mill, the support force is accurately measured with the support force to obtain the ratio. Therefore, this is calculated according to the specific value and is not related to the preset value. In addition, it can be regarded as the working pressure caused by the supporting force test roll, so the use value enterprise is cattle. The key difference between four high reversible cold rolling mill and four high cold rolling mill depends on that the cold rolling of four high reversible cold rolling mill can be carried out repeatedly without fixed orientation. Generally, four high cold rolling mill has only one orientation. Therefore, the structure and heat resistance of the two cold rolling mills are different from each other.
Four high reversible cold rolling mill is one of the four high cold rolling mills from the perspective of technical specialty. Four high cold rolling mill belongs to the technical industry of cold rolling mill, so four high reversible cold rolling mill also belongs to the technical industry of cold rolling mill. Like the general four high cold rolling mill, it is also four rolls, two support point rolls and two work rolls.
