The influencing factors and quality detection of the min aggregate breaking force

The steel wire rope is first twisted from the multi -layer steel wire, and then the rope core is centered, and a certain amount of strand twist into a spiral rope. According to different classification standards, it can be divided into different categories. For example, according to the material, it can be divided into carbon steel wire rope and stainless steel wire rope. According to the twisting method, it can be divided into single -strand rope, double -twist rope and three -twist rope. Because the wire rope has high tensile strength, fatigue strength and impact toughness, it can withstand a variety of loads and variable loads, and is widely used in metallurgy, machinery, construction, mining, transportation, navigation and aerospace, oil and gas, Marine work and many other fields.

In practical applications, affected by a variety of factors, the steel wire rope is broken and the accident occurs from time to time, and even causes serious losses to the relevant parties. In order to ensure the safety of the wire rope and prevent serious accidents caused by disconnection, it is necessary to analyze the influencing factors of the rope of the wire rope, and scientifically detect the quality of the wire rope.
Influencing factors of breaking force
Steel wire rope breakage is usually affected by a variety of factors, including its own quality, use method, environment, load bearing, etc.

1. Tensile strength of steel wire
The bearing capacity of the steel wire rope is obtained from the collection of the bearing capacity of a single steel wire. The tensile strength of the steel wire used in the steel wire rope directly affects the breaking force of the whole rope. Generally speaking, the higher the tensile strength of the steel wire, the higher the breaking tension of the steel wire rope, and the two are in a positive relationship.

2. Rope core material
The rope core of the wire rope is mainly divided into two categories: fiber core and metal core, and different materials have different effects on the overall performance of the wire rope. The fiber core can store more grease, which can better lubricate the steel wire rope, and the metal wire rope core is more wear-resistant, anti-extrusion, and the breaking tension is relatively high.

3. Uniformity of twisting
The wire rope is in the process of twisting,standing etc,The tension of the wire or strand, Uniform tension or not It also has a greater impact on the min aggregate breaking force. If the tension is not effectively controlled, the tension of the steel wire in the strand or the strand in the rope is not consistent, so that each part of the force is uneven, which will cause the aggregate breaking force is low.

4. Wire rope construction
The structure of wire rope is also one of the main factors affecting the breaking force of wire rope. According to the contact state between the adjacent layers of steel wire in the strand, the steel wire is divided into point contact, line contact or surface contact and other categories, and the force mode between the steel wire in each category is different. For example, the line contact type of wire rope is parallel lay, the inner and outer layer of steel wire contact with each other on a helix, when in a state of stress, the contact stress between the steel wire is much smaller than the point contact type of steel wire rope, with greater ability to bear the load, so under the same conditions of use, the service life of the line contact wire rope is longer than the point contact wire rope.

5. Other influencing factors
The internal structure of the wire rope is more complex, in addition to the above influencing factors, the breaking tension of the wire rope is also affected by other factors. In the in-depth analysis of its breaking force, it should be judged according to the actual synthesis of various influencing factors. For the data results obtained from the detection test, external factors such as the clamping mode of the rope breaking tensile test should also be considered to grasp the min aggregate breaking force of the rope more accurately.

Conclusion
The breaking force of the wire rope is an important basis for judging the performance of the wire rope, and it is also an aspect that should be paid attention to in the process of its quality inspection. Whether the performance of the wire rope can remain safe and stable for a long time, in addition to its own quality, it is also directly related to the care and maintenance of the wire rope in the daily use process. During the use and storage of the wire rope, collision with sharp and heavy objects should be avoided as far as possible to prevent contact with the welding machine, heat insulation measures should be taken when used in a high temperature environment, and the wire rope is often checked to ensure its safety.
