Fremgangsmåte ved oppvarming av en mantel-arbeidsflate på en roterende valse og roterbar valse for oppvarming av et banemateriale

摘要

The heated rotating roller has a cylindrical mantle body between the roller ends, composed of concentric inner (2) and outer (1) mantles, forming a ring-shaped flow zone between them for the heating medium. Dividing walls (19) between the mantles form alternating flow channels (20), each with an inflow and an outflow linked to end chambers (12,14).
