Abstract

PURPOSE:To abrade the work roll uniformly over the entire length of the roll, and to extend the roll life, by inclining the rolls along the surface of the sheet material so as to permit the roll axes of each roll couple to cross on the same vertical line passing the center line of the sheet material. CONSTITUTION:The couple of the upper work roll 1a and the upper backup roll 2a, and the couple of the lower work roll 1b and the lower backup roll 2b, are inclined along the surface of the sheet material 3 so as to permit each couple's roll axis S1, S2, (S1 is for the axis of the upper work roll 1a or the upper backup roll 2a, and S2 is for the axis of the lower work roll 1b or the lower backup roll 2b) to cross on the vertical straight line Z. Since the section shape of the sheet material 3 is bisymmetry with respect to the center line X, the sheet material 3 is rolled by the equalized roll gaps epsilon1, epsilon2, on the left and the right ends of the upper and lower work rolls 1a, 1b, and by the equalized bending forces F1, F2, loaded on the left and the right roll axes of the upper and the lower work rolls 1a, 1b.
