摘要

The invention relates to a water cooling furnace roller which can be applied for the transport of goods, for example. Strand casting material of a continuous casting plant, by means of a roller hearth - a reheating furnace. The furnace roller comprises a driven in rotation and which is mounted outside the furnace shaft (3), in particular with inner coolant channels (4, 5), and on the shaft (3) by means of a receiving bore (1) arranged, and form a conveying plane support rings (7) for the articles. The contact surfaces on the inside diameter of the receiving bore (1) of the supporting ring (7) and / or on the outside diameter of the shaft (3) are in the form of a polygon profile with locating surfaces (6, 6 ') approximately constant diameter, which is designed as a so-called weak constant diameter cam.
