Today, I saw the news of the 0.02mm "hand ripped steel" developed by Taiyuan Iron and Steel Group from WeChat News. To be honest, I am not surprised. Because "hand ripped steel" is not a surprise to me. I don’t comment on the claim that China’s thinnest hand ripped steel is currently reported in the news. Because I have seen the production of 0.03mm hand ripped steel. Although the product produced by the aluminum foil rolling mill is thinner than this, the material is different.

We don't care about the thinnest thickness, here is enough to see how our country's industrial technology strength has reached. I have seen several reports on our domestically produced "hand ripped steel" in the news before, and now I see more, which shows that our country's cold rolling mill technology is already very advanced. Moreover, our company has also sold cold rolling mills, so we still have a certain understanding of cold rolling mills, and have a little understanding of related technologies and principles.

Whether it is Taiyuan Iron and Steel Group's "hand-tear steel" or aluminum foil rolling mills of other factories, the technology of these cold rolling mills is progressing day by day. Our country's technological level is constantly improving, and we are proud of our great motherland.
