20337-402 ABSTRACT The present invention relates to an internally cooled roller for a continuous casting plant, in particular a supporting and guide roller, this having a casing of copper or alloys that surrounds a core of ferrous material and which is joined to said core, and with a wearing layer that surrounds this casing. In order to create an internally cooled, dimensionally stable roller for a continuous casting plant which has high resistance to wear and, at the same time, good thermal conductivity, and to describe a process for producing this, it is proposed that the wearing layer consist of an intermediate layer of lower thermal conductivity than copper that is applied to the casing and at least one covering layer that is applied to the intermediate layer by buildup welding.
