This paper introduces outline of the plant including major facilities, as well as technical features such as SPEOSTM (Superior Profile with Edge Oriented Shifting) technology applied for all stand of 5-stand 6-high Tandem Cold Mill. SPEOSTM is an advanced crown control technology involving shifting of special curved rolls to the axial direction. A pair of SPEOS curved rolls creates Gap Expanding Transitional Zone (GETZ) at both side of strip edge zone for any width of strip to be rolled. Strip thickness outside of GETZ becomes thicker than center naturally.
