Nondestructive Testing for Mine Wire Rope
Abstract:Mine wire rope, as key transport and hoist equipment in
the production of mine, whose safety is very important. This paper, takes
the mine wire rope as the object of study, describes the significance of
nondestructive testing of mine wire rope, analyzes its structure, fault
types and scrapped rules. In the light of the Localized Fault of the steel
rope, researches the principle and appropriate excitation technique of
magnetic leakage detection for mine steel wire rope, according to the
analysis of the basic theory of the principle of magnetic charge and the
