KT Mill (Kobe Twelve-high Mill) is a high-performance rolling mill having the respective features of our 4-high and 20-high mills, which have excellent strip flatness functions, and corresponds to the demand of improved strip flatness. Thus, the roll arrangement of KT Mill (12-high) dominates flatness control.

1. Multi-High Mills (KT/KST Mill) || KOBE STEEL, LTD.

A two-high rolling mill is assumed to be used with rolls of 250 mm diameter. The elastic modulus of the roll material is taken to be 210 000 MPa and its Poisson's ratio is 0.3.

4-Hi Mill, 4-High Mill | Waterbury Farrel

The 4-high mill is equipped with positive and negative work roll bending in order to influence the shape and the flatness of the strip. Either the work roll or the back-up roll is driven, depending on customer requirements. The diameter of the 4-high work rolls amounts to approximately 1:4 in relation to the barrel length.
