Hot-rolling flat products in a hot strip-mill. Part 2

In the first part, we reviewed the history of rolling mills and strip mills. We showed how strip mills are currently used around the world, and reviewed the development of these tools. We show how the products obtained are permanently adapted to the corresponding markets. Finally, we looked at the theoretical and practical aspects of rolling on these tools.

Let's take a look at how the technologies in place are evolving, and how operators are driving their tools to better meet user needs, in terms of dimensional performance, thermal performance and metallurgical quality. Economic requirements are also taken into account, to enable the market development of basic products derived from these tools.

Taking into account the development and improvement of existing technologies, on the one hand, and the emergence of new techniques, on the other, we propose a few perspectives and trends for the future.
