2. Which tools for which products
In this paragraph, we present the main steelmaking tools dedicated to the hot forming phase, simultaneously specifying the thermomechanical parameters (temperatures, strain rates, deformation speeds) and the order of magnitude of the "interpass times" that characterize them.
2.1 Heavy plate
Typical plate thicknesses range from 8 to 100 mm. There are two main product classes: tube plate (for the manufacture of large welded tubes) and plate, widely used in mechanical engineering. At first glance, we can say that heavy plates need to have fairly high tensile and, above all, impact strength, as well as good corrosion-resistance properties, especially for tube-type applications. Good flatness is often required, but in contrast to hot-rolled plates, the quality of...
