Steel wire rope casting manufacturers believe that steel wire rope is a deep-processed product using hot-rolled carbon steel wire as the main raw material. Its processing technology is to use hot-rolled high-carbon steel wire to make various steel wires, then twist the steel wires into multi-strand steel wire ropes, and use other materials (such as wire cores, steel wire grease, etc.) to make steel wire ropes of different varieties, different structures and different uses. The production process of steel wire rope is complex, the connection between processes is strong, the processing cycle of a single product is long, and there are many supporting equipment, which requires certain responsibility and technical proficiency of the operators.
Wire rope casting manufacturers believe that steel wire ropes are formed by outer strands wound around a core, and each strand is formed by outer steel wires wound around a core. A bit like the principle of knitting. The core of steel wire rope is mainly divided into two categories, fiber core and metal core.
Wire rope casting manufacturers believe that fiber core steel wire ropes are soft and have good bending properties. Steel wire ropes can play a buffering role when subjected to collision and impact loads during work. The fiber core is divided into natural fiber core and synthetic fiber core.
The natural fiber core has sufficient oil storage capacity to provide sufficient lubrication inside the wire rope to prevent wire corrosion.
Wire rope casting manufacturers believe that the synthetic fiber core has the characteristics of good toughness, non-water absorption, acid resistance, alkali resistance, extrusion resistance, and wear resistance. It is not easily deformed during use and has a stable diameter.
There are also two types of metal cores, metal rope cores and metal strand cores. Wire rope casting manufacturers believe that metal core wire ropes have high breaking force, are resistant to extrusion, and are resistant to high temperatures. It not only greatly improves the fatigue performance of the steel wire rope and the breaking tension of the entire rope. The structure of the steel wire rope is compact and stable, which eliminates the separation of the inner and outer ropes and the bulging of the outer strands during use of the steel wire rope.
Wire rope casting manufacturers believe that when the wire rope goes around the driving wheel and tail wheel, it is necessary to ensure that the driving wheel and tail wheel are in a horizontal state so that the wire rope runs in the center of the wheel lining groove rope. Otherwise, the wheel lining will wear too fast and the rotation of the wire rope will be difficult to eliminate. When the steel wire rope passes through all the supporting pulleys, the center line of the lining groove of the supporting pulley must coincide with the center line of the steel wire rope. Especially at the slope change point, a smooth arc must be passed to ensure that each set of double supporting pulleys is stressed evenly. . Otherwise, the rope will fall off, accelerate wheel lining wear, and the rotation of the wire rope will be difficult to eliminate, causing damage to the overhead passenger device and personal injury.
The wire rope casting manufacturer believes that the lifting mechanism is the direct execution component of the quay crane, and the lifting motor transmits power through the wire rope to lift the heavy container. The characteristic of the wire rope itself is its wearing parts. In addition to normal wear and tear, accidental collision, improper force, poor working conditions, etc. may cause the lifting wire rope to be scrapped. Therefore, the safe use of wire ropes is a major issue in the safe use of port machinery. Major accidents caused by wire rope damage or wire rope breakage occur from time to time. Wire rope damage caused by accidents also puts pressure on port safety production. Understanding the damage patterns and prevention methods of steel wire ropes has basic guiding significance for the maintenance of steel wire ropes in daily use.
