Pengetahuan dasar tentang tali kawat
First, the definition of tali kawat
The steel tali kawat is a helical wire bundle in which the steel wires whose mechanical properties and geometric dimensions meet the requirements are twisted together according to certain rules. The steel tali kawat is composed of steel wire, rope core and grease. The steel tali kawat is first twisted into strands by multiple layers of steel wires, and then twisted into a helical rope by a certain number of strands with the rope core as the center. In material handling machinery, tali kawats are used for hoisting, pulling, tensioning and carrying. The steel tali kawat has high strength, light weight, stable operation, not easy to break suddenly and reliable operation.
Second, the composition and function of tali kawat
The steel tali kawat is mainly composed of steel wire, rope core and grease.
1. Kawat baja
The steel tali kawat needs to be subjected to alternating loads during its use, and its performance is mainly determined by the mechanical properties of the steel wire, the surface state of the steel wire and the structure of the steel tali kawat. The steel wire material includes carbon steel or alloy steel, which is made by cold drawing or cold rolling. The cross section of the steel wire is round or special-shaped (T-type, S-type, Z-type). The special-shaped cross-section steel wire is mainly used for the production of sealing tali kawats. High tensile strength and toughness, and suitable surface treatment of steel wire to meet the needs of different environmental conditions.
2. Inti tali
The main function of the rope core is to support the tali kawat 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 tali kawat and prolong the service life of the tali kawat.
3. Gemuk
There are two main functions of spraying grease during the twisting process of the steel tali kawat. One is to lubricate the steel tali kawat to reduce the wear on the surface of the steel wire. act as an inhibitor.
Finally, due to the unique properties of steel tali kawats, a more ideal product has not yet been found at home and abroad to replace steel tali kawats comprehensively or in one field. Therefore, steel tali kawats are widely used in metallurgy, mining, oil and gas drilling, machinery, chemical industry, aerospace It has become an indispensable component or material in other fields, and its quality has also been concerned by many domestic industries, and a lot of manpower and material resources have been invested in the research and product development of tali kawat use.
