Causes Of Thickness Change Of 201 Stainless Steel Strip

What are the reasons for the thickness change of 201 stainless steel strip? Through research and analysis, we draw the following reasons:

1. Influence of temperature change: during rolling, the temperature of metallurgical spare parts will shake the thickness of steel strip. When the temperature changes, it will affect the metal deformation resistance and conflict factor, resulting in thickness change.

2. Influence of tension change: the tension will affect the stress. Once the tension changes, it will also change the thickness of the steel strip, especially the thickness of the head and tail of the steel strip. Of course, it will also affect other places except the head and tail of the steel strip.

When the tension is too large, it will not only change the thickness of the steel strip, but also change the width of the steel strip. Therefore, during hot rolling, micro looper can be used to stabilize the tension. During cold rolling, the roll gap of steel rolling equipment needs to be adjusted to change the rolling force, and even a relatively large frame needs to be used.

3. Influence of speed change: speed mainly affects the rolling pressure and reduction of steel strip through conflict factor, deformation resistance, bearing oil film thickness and other factors, resulting in the change of steel strip thickness.

4. Influence of roll gap change: during pressing, the size of roll gap will be changed due to the influence of factors such as thermal expansion of rolling mill parts, roll gap wear and roll bias, so that the thickness of pressed steel strip will also be changed.

Of course, in addition to the above factors, the thickness and mechanical properties of 301 stainless steel strip material will also change. In addition, if the metallurgical spare parts model itself has large errors, it will affect the accuracy of steel strip thickness.
