Imported mining steel wire rope manufacturer: rust prevention of circular steel wire rope rigging

Classification:


【Summary description】The steel wire rope produced by the imported mining steel wire rope manufacturer is mainly used for lifting, traction, tensioning, and loading ropes. Slings are called ropes, and lightweight steel wire ropes are widely used in industries such as steel and iron, chemical industry, transportation, and ports due to their high strength, light weight, smoothness, and difficulty in sudden integrity and fracture. The steel wire ropes used include phosphatized steel wire ropes, galvanized steel wire ropes Stainless steel wire rope and smooth metal wire rope.

Imported mining steel wire rope manufacturer: rust prevention of circular steel wire rope rigging

The steel wire rope produced by the imported mining steel wire rope manufacturer is mainly used for lifting, traction, tensioning, and loading ropes. Slings are called ropes, and lightweight steel wire ropes are widely used in industries such as steel and iron, chemical industry, transportation, and ports due to their high strength, light weight, smoothness, and difficulty in sudden integrity and fracture. The steel wire ropes used include phosphatized steel wire ropes, galvanized steel wire ropes Stainless steel wire rope and smooth metal wire rope.

Steel wire ropes used in the workplace, such as galvanized steel wire ropes in damp or outdoor environments, can be used as raw materials to improve rust resistance.

The wear and tear of steel wire rope slings, in addition to the ratio of the hook or suspension object to the diameter of the steel wire rope being an important factor determining the lifespan of the steel wire rope sling, is largely caused by metal fatigue caused by the repeated bending process of the bypass hook and crane.

If the number of broken wires on the worn or corroded surface or internal screw of the steel wire rope exceeds the specified value, it should be scrapped.

Steel wire ropes are mainly used for lifting, pulling, and other high-strength lines that require transportation. It is strictly prohibited to use them under the crane frame or on objects behind it.

Imported mining wire rope manufacturers tell you the difference between round strand wire rope and triangular strand wire rope

Imported mining steel wire ropes are one of the essential equipment in mines, and the safety of steel wire ropes determines the safety of many workers. Currently, mining steel wire ropes are mostly circular and triangular.

So what is the difference between these two types of steel wire ropes? Usually, under the same diameter, compared with triangular strand wire rope, triangular strand wire rope has better flexibility and greater breaking force. However, due to its high rotation coefficient, it is not conducive to deep well lifting and is prone to defects such as oil leakage. Circular wire rope has good flexibility, avoids stress concentration, reduces friction resistance between wires, and has higher bending and fatigue resistance than triangular strand wire rope.

At first, the steel wire ropes used in China were all triangular strands. Beckett introduced European WDI and German produced round strands to China, which changed the unchanged trend in China and greatly improved the safety of domestic coal mines.

In summary, triangular strand steel wire ropes are not suitable for deep well operations! At present, most deep well steel wire ropes in China are round strand steel wire ropes. In the Basic Theory of Mine Hoisting System, it is also pointed out that the torsion of the steel wire rope causes uneven stress distribution on the cross-section of the steel wire rope. What will the result of torsion be? The inner and outer strands of the steel wire rope are overloaded, especially when twisted in the same direction, the stress of the inner strand is 4.47 times that of the outer strand. Therefore, deep well friction hoists are not suitable for using triangular strand steel wire ropes twisted in the same direction, and circular strand steel wire ropes become the ideal choice!
