Six-high rolling mill stand and finishing mill train for hot rolling an intermediate strip into a thin strip

Six-high rolling mill stand for hot rolling an intermediate strip into a thin strip, the rolling mill stand comprising:

• an upper work roll and a lower work roll for hot rolling the intermediate strip between the upper work roll and the lower work roll into the thin strip,
• work roll bending blocks for bending the work rolls in vertical direction;
• two axial shifting devices for axially shifting the work rolls;
• two intermediate rolls for supporting the work rolls in vertical direction
• intermediate roll bending blocks for bending the intermediate rolls in vertical direction;
• and
• two backup rolls for supporting the intermediate rolls in vertical direction,
• wherein each intermediate roll has a first tapered portion, in axial direction followed by an intermediate portion, and followed by a second tapered portion,
• wherein a roll crown of the intermediate portion follows an even function with respect to the centre of the intermediate portion fin width direction,
• wherein each tapered portion features a large diameter adjacent to the intermediate portion and a comparatively smaller diameter on outside.
