less than 600 mm is narrow strip steel, while strip steel exceeding 600 mm is broadband steel. The first hot strip mill was put into production in the United States in 1905 to produce strip with a width of 200 mm. In 1926, the first hot wide steel strip rolling mill was completed and put into production in the United States, which led to the ...
The company operates four hot strip mills at its sites in Duisburg and Bochum, with an annual output of almost 12 million tons. The hot strip mill in Beeckerwerth is the largest with a capacity of around 6 million tons per year. To produce hot-rolled steel, slabs are rolled into thin strip in a series of mill stands at temperatures of more than ...
Since close to half of all steel produced is hot-rolled to strip, mills require maximum throughput and availability combined with geometrical precision and the ability to create optimum material properties. High-performance …
IRON & STEEL TECHNOLOGY I AIST.ORG Strip Steering Control — A Cutting-Edge Technology for Hot Strip Mills Stability of the hot strip mill roll-ing process remains a main topic when it comes to processing thin and hard materials. Strip steering, especially at the end of rolling and tail-out rips, is a main source of unscheduled downtimes in a hot
The hot strip mill was widely overhauled in the late 1980ies (receiving a new roughing stand). British Steel merged with Koninklijke Hoogovens from the Netherlands to form Corus in 1999. Eigth years later Corus was taken over by the Tata Steel group from India. Blast furnace No. 4 was completly rebuilt in 2012.
