Failure Analysis of a Large Spincaster (and Why a Fracture is not an Explosion)

Technical Article---Peer-Reviewed

Abstract

The analysis concerns back-to-back losses of a spincaster used in the manufacture of rolls for rolling mills. Both losses involved the fatigue fractures of parts used to secure the mold for the roll being cast in position while spinning. The fractures are analyzed as to cause so as to avoid yet another occurrence. Further, since the loss incidents were accompanied by loud noises and by molten metal flying about, interpretation of the fracture also involved dispelling the notion that there was an “explosion.”
