Two factors cause fatigue stainless steel wire rope stainless steel wire rope used to ensure the proper use of an important guarantee for life, but in the actual application process, due to the carelessness of the operator, that there is no standard operation fatigue caused by the use of wire rope, causing some security risks. Here, we summarize the next two reasons. The first one is bending fatigue, stainless steel wire rope through a pulley or drum repeat the scratch on the scratch, the numerous curved, easy to wire fatigue, toughness decreases, resulting in broken wires. Fatigue broken wires appear on the degree of curvature of the most powerful outer wires. Under normal circumstances, the production of stainless steel wire rope, fatigue broken wire stainless steel wire rope meant nearing later use. Tests showed that bending fatigue life and D / d ratio of stainless steel wire rope (ie the ratio of the diameter D and the rope drum diameter d), the safety factor and rope structures are closely related. The second is stretching, twisting and fatigue caused by vibration, stainless steel wire rope in starting and braking the whole story, tied the rope around the load bearing tensile stress can cause metal fatigue. In addition, stainless steel wire rope is often distorted and vibration is also the reason for fatigue. Principle of fatigue damage under variable stress, fine wire surface first initial crack formation due to a variety of slip, then the crack tip under the action of shear stress repeated plastic deformation, so that crack until it breaks. Broken wire caused by general fatigue fracture flush, most appear on the surface of the wire, and very regular. Stainless steel wire rope and standards is essential, we can control the factors listed above stainless steel wire rope, to avoid improper use, so as to effectively prevent the use of stainless steel wire rope fatigue, and create conditions for extended service life. Stainless steel core wire rope is the middle is composed by a surge of stainless steel wire rope. IWS or IWR letters represent. In addition to hemp core, is a steel core, stainless steel wire rope in general is both cores. Stainless steel core wire rope wear than the fiber core stainless steel wire rope stainless 丝绳拉 lock, anti-extrusion, has a high service life, breaking force is relatively high, relatively low softness point. Because of wear compression and stainless steel core wire rope hoists or generally applicable to the top with winches. Stainless steel core wire rope core steel prices relatively high ratio of hemp rope a little, but taking into account the life and stainless steel wire rope tension will be relatively better, so overall cost stainless steel core wire rope is relatively low.
