With the reform of electronic and automated machinery and equipment, many users have become more and more strict with precision stainless steel strips. Compared with ordinary ones, its thickness is thinner and the surface is smoother. During the production of precision stainless steel strips, rolling through will occur. Once the rolling through occurs, it will affect the stability and quality of the product. Let's analyze the reasons for rolling through, I hope the content of the article will be helpful to you.
The reasons that lead to the wear of precision stainless steel strip mainly include the thermal expansion of the roll, the thickness of the stainless steel strip, the change of tension, and the incorrect tension parameters. The following will introduce them one by one:
1. Thermal expansion of the roll
When the precision stainless steel strip is pressed, the friction of the roll brings a lot of heat. When the rolling speed and the cold and heat of the roll surface are not uniform, the thermal crown of the roll will change, which will eventually lead to the deformation of the stainless steel strip.
2. Thickness and tension change of stainless steel strip
If the thickness of the stainless steel strip is not uniform, the deflection will change, and the tension will change, which will lead to changes in the horizontal distribution law, both of which will cause changes in the rolling force, resulting in rolling through accidents.
3. The tension parameter is wrong
According to statistics, there is a positive correlation between the number of rolling and tension parameters of precision stainless steel strips, and the smaller the tension deviation, the less likely a rolling-through accident occurs. Generally, the unit tension of the inlet can be adjusted maliciously to reduce the probability of pinching.
The production process of precision stainless steel strips is relatively complex. In the production process, the requirements for the process are relatively high, and the production equipment is relatively complex. In order to ensure the high quality of the products, we must pay attention to the production details.
