METHOD OF MAKING STEEL ROPE CROSS SECTIONAL LOSS SIMULATORS Russian patent published in 2012 - IPC G01N27/82 

FIELD: physics.

SUBSTANCE: set of steel rope cross sectional loss simulators is made, where each simulator consists of a bundle of steel calibrated wires bound together, having different diameter and corresponding to 0; 10; 15; 20 and 25% of cross sectional wear of steel ropes. Each simulator is made from instrument steel U8, which first undergoes thermal treatment until achieving magnetic permittivity of 19-21 SI units. The steel wires have diameter 1 mm and 5 mm, length of not less than 1 m, and a layer of dielectric coating with thickness of not less than 0.1 mm is deposited on their surface. Thermal treatment is carried out by placing the simulators into a furnace heated to temperature 750°C, and holding at that temperature for 10 minutes and then cooling in water to room temperature. The dielectric coating layer is deposited by open sputtering. The wires are bound together by epoxy resin.

EFFECT: high reliability of monitoring wear of different types of ropes and minimising the effect of different types of steel of the ropes on monitoring their wear and operating conditions.
