Control with Shapeline gauge: Nippon Steel Oita works control novel leveller

A cooperation between Shapeline and Nippon Steel has resulted in a common project to install a flatness gauge in Nippon Steel No 1-line in Japan, Oita works.

The gauge will be installed after the novel Oita Plate Leveller (OPL), unique of its kind. The OPL works as a skin-pass mill for plates, with the rolling force controllable in 19 sectors across the plate width. The Shapeline system will provide data correlated to the position of these 19 sectors to control the leveller and improve plate flatness. A description of the OPL can be found in “Development of New Intelligent Plate Leveler at Oita Plate Mill” by Wakatsuki et. al., Proc. 10´th International Steel Rolling Conference, Beijing, Sep. 15-17 2010
