About the sound
On the recording, a sizing press can be heard processing crude steel billets in the hot rolling mill of the Stahlwerk (steelworks) of Thyssen-Krupp in Duisburg. 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 size for hot rolling in the so-called sizing press. A sizing press enables the 1250 °C hot billets to be shaped into 12 standard sizes, optimally prepared for rolling.
