Patent ID: 8006742

Claim:
A casting roll, comprising: a cylindrical roll body with axial end marginal portions; side weirs abutting the axial end marginal portions of said roll body; a short tube-shaped support coaxially protruding from said roll body; a stub axle fitted into said support; a sleeve fitted over said support; and a flange contiguous with said stub axle and abutting on the sleeve on a side away from said roll body, wherein said roll body is formed with longitudinal cooling passages passing through the roll from one end to the other end of the roll only within a range between said side weirs, and radial cooling passages each adjacent to a corresponding end of the roll and extending from an inner periphery of the roll to a corresponding longitudinal cooling passage, wherein a plug is fitted into each end of the longitudinal cooling passages and abuts on said sleeve such that said plug is disposed between one of the ends of said longitudinal cooling passages and one of said side weirs in a direction parallel to the axis of said roll body, whereby cooling water can flow through one of the radial cooling passages, the longitudinal cooling passage and the other radial cooling passage in the order named, and wherein a radial contact distance between said side weirs and said roll body is greater than a radial distance between said longitudinal cooling passages and an outer periphery of said roll body.
