Abstract

PURPOSE: To drop the contact pressure between a roller and end parts of a substance to be treated and to prevent the occurrence of a pickup phenomenon by forming the roller with a heat resistant steel contg. a restriced amount of Al and by tapering end parts of the roller so that the diameter is reduced toward the outside.
CONSTITUTION: A heat resistant conveying roller is made of heat resistant steel such as Cr-Ni steel contg. 0.35W10wt% Al. Both end parts of this roller 4 through which both end parts of a substance 5 to be treated pass in a contact state are gently tapered so that the diameter is reduced toward the outside, thereby relieving the contact pressure applied by the edges of the substance 5. Thus, a pickup phenomenon is prevented, and the life of the roller is elongated. By coating the tapered parts 6 with ceramics, a more superior pickup perventing effect is produced.
