6x37 +FC(IWS/IWR) round strand wire rope (smooth/galvanized) in material handling machinery for hoisting, lifting, pulling, tensioning and load bearing. The steel wire rope has high strength, light weight, stable operation, not easy to break suddenly, reliable operation, and the nominal tensile strength of 1570Mpa, 1670Mpa, 1770Mpa, 1870Mpa and 1960Mpa can be provided. The main function of the rope core is to support the wire rope to achieve a stable cross-sectional structure. The rope core includes steel core and fiber core, fiber core includes natural fiber core and synthetic fiber core, natural fiber core such as sisal, jute, cotton thread, etc., synthetic fiber core includes polyethylene and polypropylene filament, etc. The natural fiber core can store more grease, which can lubricate the wire rope and prolong the service life of the wire rope. There are two main functions of spraying grease during the twisting process of the steel wire rope. One is to lubricate the steel wire rope to reduce the wear on the surface of the steel wire. play a controlling role. The other is to isolate the steel wire surface from the oxygen in the air and control the oxidation and corrosion of the steel wire rope.
Safety factor is a certain factor to ensure the safe and reliable work of wire rope. Different equipment requires different safety factors. For example, the safety factor of elevator is 12. The breaking force of steel wire rope mainly depends on the tensile strength, diameter and structure of steel wire rope, which is an important content to ensure the safety factor. When the diameter and structure of the wire rope are determined, the higher the tensile strength of the wire rope, the greater the breaking force. Generally speaking, choosing a higher tensile strength is conducive to improving the safety factor in use, but it should be noted that increasing the strength will affect the toughness of steel wire. Therefore, the strength and toughness of steel wire should be considered comprehensively according to the application occasion. Extrusion resistance The resistance to structural deformation in use is called extrusion resistance, which can also be said to be the stability of the structure. The extrusion resistance of steel wire rope mainly shows its resistance to lateral extrusion, especially when the steel wire rope is wound on the drum in multiple layers. Generally speaking, the structure of steel wire rope with metal core is more stable than that with fiber core, and the number of steel wires in the strand is relatively stable. Line contact is better than point contact, and surface contact is better than line contact.
