[PDF] Strip tracking in hot strip mills

Strip tracking in hot strip mills. In the finishing mill, steel strip is rolled from thick slabs through pairs of rollers housed in a continuous train of seven roll stands. As the strip is rolled, unwanted lateral movement, known as strip tracking, can cause the strip to collide with the edge of the mill. Strip tracking control is currently a

Influence of Roll Wear in Hot Rolling of Steel at Hot Strip Mills

12.08.2021Work rolls are exposed to high material temperature typically in the range of 1150–1050 C at roughing mills and 1000–850 C at finishing mills during rolling of carbon steels. Simultaneously, rolls are cooled with water spray to avoid their overheating. There is also conductive heat transfer within the roll in radially inward direction.

Historical Development of Rolling Mills – IspatGuru

24.01.2021Early hot strip mills did not produce strip suitable for tinplate, but in 1929 cold rolling began to be used to reduce the gauge further. The first hot strip mill in the United Kingdom was opened at Ebbw Vale in 1938 with an annual output of 200,000 tons. By 1961, the early hot strip mills had been upgraded or replaced by larger capacity semi
