Abstract
A method which can readily and accurately detect the depth of cracks in the rolls for transferring hot steel ingot blooms is disclosed. In operation, a fluid of a desired pressure is fed into a plurality of elongated holes formed in the rolls, such elongated holes being disposed in a direction parallel to and along the axis of the rolls and also equidistantly below the round surface of the roll. When cracks occur and reach the elongated holes, the fluid leaks through cracks from the elongated holes and such leakage causes a change in the amount of flow of the fluid. Thereby the cracks can be readily detected by measuring such change of fluid flow by a suitable known detector.
