Steelwork: Hot rolling

The hot rolling of crude steel billets in the hot rolling mill of the Stahlwerk (steelworks) of Thyssen-Krupp in Duisburg can be heard on the recording.
In the hot rolling mill, the process of hot rolling is carried out, a metalworking process in steel production: rolling at high temperatures makes possible a significant reduction in thickness. For example, crude steel billets are reshaped into hot-rolled strip (a hot-rolled product with a rectangular cross section and a width of at least 600 mm). The crude steel billets, which have already been heated in the pusher furnace, are rolled into hot-rolled strip on a continuously running production line. In this process, the billets are shaped into the required sizes in the so-called roughing mill and sizing press. This usually consists of five to seven consecutive four-roll stands with two work rolls and two back-up rolls each.
In one pass they roll the strip coming out of the roughing mill until the desired thickness of the hot-rolled strip is achieved.
The final processes in the continuous production line include an exit roller table with cooling devices and the coiler.
