Tbar Rolling Process with Universal and Edger Mills

open access Use of Tbars in shipbuilding has increased recently. Although Tbars having a web height of at least twice the flange width are generally required for ships, the dimensions of existing hotrolled Tbars are not suitable. As a result, Tbars for ships are typically fabricated by welding two plates.

Development of Modern Hot Strip mill and its Main Features

JFE steel commissioned their Ohgishima hot strip mill in May 1979. Although a very wide strip mill (2,400 mm roll barrel), it reverted to the specific coil weights associated with the 'Generation 2' mills of 18 kg/mm. It is a threequarter continuous mill, a layout with a long history in Europe prior to its adoption in Japan.
