'HaiYangShiYou 115' anchor chain broken wire cable material test and breakage analysis

摘要

"HaiYangShiYou 115" chain cable in use process was found in more broken wires.Through the chemical composition analysis,mechanical property testing,fracture analysis,metallographic examination methods,the cause of the broken wire are analyzed.The results show that:the material of steel cable anchor chain mechanical performance is basic comply with the design requirements,the broken wire fracture is relatively serious wear,all send the samples of the present wear trace shape is consistent,should be the same kind of wear the way by damage,and reduced the steel wire tensile strength,lead to fracture.
