Abstract

A method for manufacturing a roll mantle or roll body for a roll line of a continuous casting apparatus that has a shaft includes casting a metal to form the roll mantle or roll body such that the roll mantle or roll body includes at least one internal channel. The roll mantle or roll body has a first end region, a second end region and a central region between the first end region and the second end region, the central region extending along at least 50% of a length of the roll mantle or roll body, and the internal channel may be formed in the central region. The internal channel may also include a pattern or projection.
