Stainless Steel Wire Rope Of The Service Life
People in the use of stainless steel wire rope, Stainless Steel Wire Rope the most hope is as much as possible to extend the life of stainless steel wire rope, but the light is not, but first of all to understand what factors will affect the life of stainless steel wire rope in order to prescribe the right medicine. In the daily inspection of stainless steel wire rope, we must pay close attention to the use of stainless steel wire rope state, Stainless Steel Wire Rope to guard against the phenomenon of elastic reduction. In some cases (usually related to the working environment), the elasticity of the wire rope will be significantly reduced, then if you continue to use the operation will bring a lot of security risks.
1, the production process. Stainless steel wire rope is made of a number of stainless steel wire twist finished product, stainless steel wire and twist the quality of the process determines the quality of stainless steel wire rope. The stainless steel wire is usually hot rolled from the high-quality steel ingot into a smaller diameter disk circle, and then after repeated cold drawn from the diameter of stainless steel wire. Stainless Steel Wire Rope If the quality of stainless steel wire and twisting process can not be guaranteed, it is necessary to reduce the service life of stainless steel wire rope. Therefore, the stainless steel wire rope in the production process must first ensure that the quality of stainless steel wire and twist the process, so basically to ensure the quality of stainless steel wire rope to extend the life of stainless steel wire rope.
2, wear. Wear is divided into external wear and internal wear. External wear is mainly in the course of the use of stainless steel wire rope and the rope floor and other objects caused by surface contact, so the actual work should be on the regular stainless steel wire rope down to avoid Unilateral wear situation, Stainless Steel Wire Rope as far as possible to make the whole stainless steel wire rope wear. Wear the stainless steel wire rope diameter narrow, breaking load reduced. Internal wear is mainly stainless steel wire rope through the reel or pulley when the load is mainly pressed on the side of the stainless steel wire rope, and because of the bending of stainless steel wire rope, stainless steel wire rope between the various steel wire between the force, Stainless Steel Wire Rope Between the shares and the increase in the force between the shares, so that the internal wear and tear of stainless steel wire rope, when the frequent work of the concentration of force, so that internal broken wire. Wear greatly reduced the life of Senyuan stainless steel wire rope.
3, broken wire. Stainless steel wire rope broken wire is divided into the use of broken wire and the use of broken wire, so "coal mine safety regulations" provides stainless steel wire rope in the suspension before and in the use of monofilament performance testing. In use, Stainless Steel Wire Rope because the stainless steel wire rope repeated in the sheave or reel around the winding, numerous bending, easy to make steel wire fatigue, toughness decreased, and ultimately lead to broken wire. The non-product quality factors caused by the broken rope accidents and the promotion of work there is a different degree of relationship. Stainless Steel Wire Rope The broken wire caused by fatigue generally appears on the outer side of the wire with the most severe curvature of the strands. Bending fatigue broken wire will increase as the load increases and the bending angle decreases.
4, stainless steel rope elasticity tend to be accompanied by the following several phenomena:
B. Wire rope twist extension;
C. As the parts are pressed against each other, there is a gap between the wires and the strands;
D. The slight brown powder appears in the strands of the rope;
E. Although not broken, but the wire rope is not easy to bend and diameter reduction is simply because the wire wear caused by the much faster. This situation will lead to sudden deformation in the dynamic load, it should be immediately scrapped.
