Guide roll for feeding steel bars into hot rolling mill - where flanged rings are used to clamp replaceable guide roll made of wear resistant steel

摘要

The roll possess a journal on which two carrier rings (14,15) made of a non-wear resistant material are located, pref. via two rolling bearings. Each ring (14,15) ends in a flange. The two flanges are used to clamp and centre an outer ring (24) which is made of wear resistant material and forms the actual guide roller. Ring (24) pref. projects radially outwards beyond the two flanges on rings (14,15). Ring (24) has a long working life, so repair and maintenance costs are reduced; and the ring (24) is easily replaced when it is finally worn beyond repair.
