Literature Review of Research on the Technology of Wire Rope Nondestructive Inspection in China and Abroad

摘要

As consumables in mine, wire ropes have great significance for safe operation of coal mines. The complex structure makes the nondestructive testing particularly difficult. This paper summarizes the existing methods of analysis at home and abroad from the perspective of strong magnetic and weakly magnetic; introduces the main methods of wire rope at the present, including principle and current status. At last, several critical problems in nondestructive testing of wire rope are discussed.Key words: wire rope / nondestructive testing technology / electromagnetic detection method
