Claims

[Claims for Utility Model Registration] ■ A plurality of annular recesses are formed in the roll shaft, bearings are provided in the annular recesses for bearing support, and the roll shaft between the annular recesses is provided with a sleeve or a built-up layer. In a pinch roll for continuous g-making equipment equipped with a sleeve or overlay, the axial length of the sleeve or overlay is shorter than the length of the roll shaft between the annular recesses, and rings are provided at both ends of the sleeve or overlay. 17. A pinch roll for a continuous casting device, characterized in that the ring, the sleeve, or the build-up layer are integrally fixed by welding the outer peripheral surfaces of abutting end surfaces. ■ The axial length of the ring is longer than (0,3t+4)ys when the thickness of the sleeve or built-up layer is t-1rrIn, t1rr! The pinch roll for continuous casting equipment according to claim 1, which is shorter than n. (2) The pinch roll for continuous casting equipment according to claim 1 or 2, wherein the wall thickness of the ring is equal to the wall thickness of the sleeve or built-up layer. ■ The ring has a concentric groove in the axial direction at the end of the bearing side, a protrusion concentrically in the axial direction at the end of the bearing cover that encloses the bearing, and the groove and the protrusion are connected to each other. A pinch roll for a continuous casting apparatus according to any one of claims 1 to 3, which is combined to form a labyrinth backing.
