ThyssenKrupp Steel Europe spent a quarter of a million euros on renovating its hot-strip rolling mill in Duisburg. The animation shows how it all works.
Such hot-strip mills roll steel slabs up to 35 tons heavy into strips up to two meters wide and only one millimeter thick. The steel strip is still at temperatures of up to 600 degrees Celsius when coiling under tension between the pinch rolls. If the surface of a roll becomes damaged, the quality of the strip surface suffers.
The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a key element of steel production. Since close to half of all steel produced is hot-rolled to strip, mills require maximum throughput and availability ...

These rolls can either be flat or grooved contoured for the hot rolling of rods or shapes. Under these conditions, the rolls grip the piece of metal and deliver it, reduced in cross-sectional area and therefore, increased in length. x The initial hot-working operation for most steel products is done on the primary roughing mill
Secondary scale on hot strip and the impact on wear is another issue. Stresses from Hertzian pressure in 4-high cold mill back up rolls were measured years ago, the results were never published, but of high interest - also, maybe later. K. H. Schröder July 2003 K. H.

Henry Cort is also called “father of modern rolling”. The first rail mill was established in 1820 while the first plate mill was exhibited in 1851. Three high mills for rolling heavy sections were introduced in 1853. Hot strip mill were developed in America in the first half of the twentieth century. Basic concept of the rolling
