Abstract

PURPOSE: To enable the detection of a crack developing depth simply and accurately even during the operation by monitoring the flow rate of a constant pressure fluid in a slot provided axially on a roll.
CONSTITUTION: Slots 2... are provided axially at a desired depth from the outer surface of a roll 1. When a constant pressure fluid is fed through the opening of the slots 2..., the developing depth of a crack 3 can be detected simply and accurately even during the operation of the roll 1 by reading changes in the flow rate of the fluid by means of flowmeters 4....
