Hitachi's HC-MILL simultaneously increases yield, improves shape and crowning control, minimizes edge drop, and increase rolling stability. |

| This undesirable contact area results in a bending force which causes edge drop. | ||

In an ideal mill, the width of the rolls would be exactly equal to that of the work. Of course, this is impractical, since the rolls would have to be replaced every time the width of the work changed. |  |

| Undesirable contact area is virtually eliminated by shifting
the intermediate rolls axially, as shown. This can be done quickly
and easily, making the HC-MILL the ideal solution for the real
world. Use of the HC-MILL not only significantly improves quality, but has significant ramifications for the system as a whole. Hot rolling with the HC-MILL makes possible schedule-free rolling (SFR), offering increased production flexibility, reduced storage and delivery times, and higher overall quality. |
