Abstract
A metal bar undergoing hot rolling is sheared by a pair of shear knives which form a rounded wedge shape at a downstream end of the bar to minimize split ends and cobbles during the rolling operation. The two knives have respective, mating male and female sections which have peripheral cutting edges defining the rounded wedge shape. The shape and angular parameters of the peripheral cutting edges on the two knives provide a progressive, scissors-like, shearing action along the cutting edges from their upstream ends to their downstream tips.
