Rapid Wear of Shell Liner Due to Severe Abrasion
A high-chromium white cast iron shell liner installed in an ore crusher sustained impact damage in the course of operation. Visual-optical examination revealed horizontal cracks on the surface of the liner along with particles that had fractured off. Metallographic examination indicated a heavily deformed surface layer with chip formation at the wear surface. The chemical composition of the liner was found to be Fe-2.74C-0.75Mn-0.55Si-0.51Ni-19.4Cr-1.15M. This alloy is highly resistant to abrasive wear, yet at the same time, prone to chipping because little plastic displacement will occur at the surface. The liner failed as a result of severe abrasion caused...
