Abstract (en)

A roller for transporting hot objects, comprises a cylindrical steel core (2) and on the core a plurality of annular elements (3) for contacting the hot objects which elements are slidable axially along the core and each comprise a refractory filling (10) and an outer hard surface material (9). To prevent tensile stresses and provide long life, the outer hard surface material is a jacket (4) of an industrial ceramic material and between each adjacent pair of the annular elements (3) there are means on the core (2) for maintaining the elements spaced apart in the form of at least one annular disc (12) of diameter less than the elements (3).
