Stainless Steel Cold Strip Mill usually consists of multiple rolls, such as working rolls and support rolls. The working rolls are in direct contact with the stainless steel strip, while the support rolls are used to support the working rolls to increase the rigidity and load-bearing capacity of the working rolls. When the motor drives the rolls to rotate, the rolls exert strong pressure on the stainless steel strip being fed in. Under pressure, the atomic lattice structure inside the Stainless Steel Reversing Mill slips and reorganizes, causing the strip to undergo plastic deformation. The thickness gradually decreases, and the width and length increase accordingly.
Tension control
Tension control is a very important link in the Cold Rolling Mill Steel process. By setting tension devices at the entrance and exit of the strip, a certain tension is applied to the strip. The main functions of tension are as follows: First, it helps the strip maintain a stable operating state to prevent deviation and shaking; second, it can reduce the rolling force, because tension can make the strip more prone to plastic deformation during the rolling process, thereby reducing the pressure of the rolls on the strip; third, it can improve the strip shape. By reasonably adjusting the tension distribution, the strip deformation in the width direction can be made more uniform, reducing plate defects such as waves and bends.
