Failure Analysis of Hard Alloy Roll Rings and their Repairing Technology

Abstract:

Roll rings are important parts in bars, and wire rolling, and their number consumed is large. They can fail and fracture due to defects of their own material and poor working conditions. There are many measures to prolong service life of roll rings, for example, their correct use and maintenance, suitable material, advanced manufacturing technology, and well machining quality, but mixed wear is inevitable. Such problems as surface defects and negative deviation of roll’s diameter caused by mixed wear can be solved by advanced repairing technology to make them meet users’ requirements, and prolong service life.
