What are the advantages of steel core wire rope?
Steel wire rope is the mechanical properties and geometric size of the steel wire in accordance with certain rules twisted together spiral wire bundle, steel wire rope by wire, rope core and grease composition. Wire rope is twisted into strands by multiple layers of steel wire, and then centered on the core of the rope, twisted into a spiral rope by a certain number of strands. Because of its high strength, light weight, stable work, not easy to suddenly break the whole root, reliable work and is widely used in all walks of life.
Wire rope core plays a supporting role in the entire operation of the wire rope to achieve a stable cross-sectional structure. Steel wire rope is divided into hemp core and steel core two categories according to the rope core.
Hemp core wire rope soft, good bending performance. When the steel wire rope is subjected to collision and impact load in the work, the fiber core can play a buffer role. The natural fiber core holds more oil, and the steel wire rope has enough lubrication inside when it is working, and can slow down the corrosion of the steel wire.
Steel core wire rope is composed of a wire rope in the middle, represented by the letters IWS or IWR.Steel wire: It is the basic strength unit of steel wire rope, which requires high strength and toughness.
Strand: Each small strand of wire twisted. The same diameter and structure of the steel wire rope, the number of strands is high fatigue strength.
Metal core wire rope has the following characteristics: metal core wire rope breaking tension, extrusion resistance and high temperature resistance.
The main feature of the steel core wire rope is that the tension is stronger than the hemp core wire rope, and the metal density coefficient is increased by 17% compared with the same structure wire rope. The elongation of the wire rope is low, the structural stability is high, and the average life can be increased by 1.2-1.3 times than that of the hemp core.
Another feature of steel core wire rope is wear resistance, high temperature resistance and extrusion resistance, because of wear resistance and pressure resistance, steel core wire rope is generally used in cranes or winches. In terms of high temperature resistance, steel core rope is higher than hemp core wire rope, so some high temperature occasions generally choose steel core wire rope.
