Fig.1 Example of 12XAmill analysis under conditions IMR shape and IMR shift amount

(Rolling material Young’s rate E=19,694kg/mm2 )

【Calculating conditions and Results】

No.1(Red) IMR is Flat roll (no taper on one side), No.2(Yellow Green) is matched the IMR taper shoulder position and material width edge, No.3(Blue) is matched the IMR taper shoulder is within 45mm from the material width edge.　⇒　IMR taper on one side and by its shoulder position shifting within material width, Delivery material crown changes from convex to concave, and in either case, upper and lower WRS are kissing rolling.

Fig.2 Mill Delivery shape of 12XAmill analysis under Fig.1’s same conditions,



【Calculating conditions and Results】

No.1(Blue) IMR is Flat roll (no taper on one side), No.2(Brown) is matched the IMR taper shoulder position and material width edge, No.3(Glay) is matched the IMR taper shoulder is within 45mm from the material width edge.　

⇒　IMR Flat and taper on one side and by its shoulder position shifting within material width, 

Delivery material shape changes from Edge Wave to Center Wave, and Moreover,

No.2(Brown) is almost Dead Flat Shape.
