Roller-conveyor roller for the transport of furnace-heated metallic strip material

摘要

A roller-conveyor roll for the transport of furnace-heated metallic strip or a continuously cast steel strand has a shaft extending along an axis, a tubular shell coaxially surrounding the roller shaft and having a pair of axially spaced ends, and a respective insulating body at each of the shell ends between the respective shell and the shaft and angularly fixed to the shell and to the shaft for transmitting torque between the shaft and the shell ends. The body electrically and thermally insulates the shell from the shaft.
