Title:
ROLLING ROLL, ROLLING MILL AND ROLLING METHOD
Document Type and Number:
WIPO Patent Application WO/2007/129650
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a rolling roll, a rolling mill and a rolling method in which the
board crown of a rolled material can be corrected effectively while edge drop can
be reduced, and damage to the roll due to local line pressure rise between rolls is
prevented. [MEANS FOR SOLVING PROBLEMS] A roll crown is formed by a continuous curve
having a maximal value point and a minimal value point where the central region
held between the maximal value point and the minimal value point represents one
function, and the end region from the maximal value point to a closest roll end
represents a function having an inclination of steeper gradient than that of
the extension of the function in the central region (i.e., the radius decreases sharply
toward the roll end).
