Stainless Steel Wire Ropes The Service Life

Jiangsu GT Inox Co.,Ltd | Updated: Aug 09, 2017

People in the use of stainless steel wire rope, Stainless Steel Wire Ropes the most hope is as far as possible to extend the service life of stainless steel wire rope, but the light is not good, first of all to understand what factors will affect the service life of stainless steel wire rope, Stainless Steel Wire Ropes to the right remedy. In the daily inspection of stainless steel wire rope, we should pay attention to the use of stainless steel wire rope in a timely manner, to be wary of elastic reduction phenomenon. In some cases (usually related to the working environment), the elasticity of the wire rope will be significantly reduced, Stainless Steel Wire Ropes at this time if the continued use will bring great security risks to the operation.

1. Production process. Stainless steel wire Rope is made from a number of stainless steel wire twist of a finished product, stainless steel wire and twist process quality determines the quality of stainless steel wire rope. The stainless steel wire is usually made from hot-rolled steel ingots into a smaller diameter disk round, Stainless Steel Wire Ropes and then after many cold drawn after the diameter of the stainless wire unequal. If the quality of stainless steel wire and twist process is not guaranteed, the service life of stainless steel wire rope must be reduced. Therefore, stainless steel wire rope in the production process must first ensure the quality of stainless steel wire and twist technology, so basically can ensure the quality of stainless steel wire rope, Stainless Steel Wire Ropes prolong the service life of stainless steel wire rope.

2. Wear and tear. Wear is divided into external wear and internal wear. The external wear is mainly stainless steel wire rope in the use of its periphery and the surface of the rope and other objects, Stainless Steel Wire Ropes such as the floor, so the actual work should be on a regular basis to the stainless steel wire rope to avoid unilateral wear, as far as possible to make stainless steel wire rope all week wear. Stainless Steel Wire Ropes The abrasion makes the rope diameter of stainless steel wire rope become fine, and the breaking load is reduced. Internal wear is mainly stainless steel wire rope through the reel or pulley when the load under the main pressure on the side of the stainless steel wire rope, at the same time because of the bending of stainless steel wire rope, Stainless Steel Wire Ropes stainless steel wire rope inside each other to create the force between the wire, so that the wire and wire between the strands and the force between the increase, so that the stainless steel wire rope internal wear, when frequently working force concentration, Stainless Steel Wire Ropes so that the internal broken wire. Stainless Steel Wire Ropes The wear and tear greatly reduces the service life of the source stainless steel wire rope.

3, broken silk. The broken wire of stainless steel wire rope is divided into the manufacture of broken wire and the use of broken wire, so "coal mine Safety Regulations" stipulates that stainless steel wire rope in the suspension and use of single wire performance testing. In use, as the stainless steel wire rope repeatedly in the rope wheel or reel around, countless times of bending, Stainless Steel Wire Ropes easy to make the steel wire fatigue, Stainless Steel Wire Ropes toughness decline, resulting in a broken wire. The broken rope accident caused by the non product quality factor has a different degree of relationship with the lifting work. The broken wire caused by fatigue usually appears on the outer layer of the steel wire with the most bending degree of the stock.Stainless Steel Wire Ropes The bending fatigue breaking wire will be aggravated with the increase of load and the decrease of bending angle.

4, stainless steel wire rope elastic reduction will often accompany the following phenomena:

A. Reduction in rope diameter;

B. Wire rope twist distance elongation;

C. Due to the tension between the parts, the gap between the steel wire and the rope stock is missing;

D. Fine brown powder appearing in the recess of the rope;

E. Although no broken wire was found, the apparent difficulty in bending and diameter reduction of wire ropes was much quicker than that caused by the abrasion of steel wire. Stainless Steel Wire Ropes This situation can cause a sudden rupture under the action of dynamic load, so it should be scrapped immediately.
