Phosphating coated steel wire rope, a patented product in the past two years, is very wear-resistant after manganese phosphating. It is an ideal upgrade product of smooth steel wire rope, and its service life has exceeded that of steel wire rope imported from developed countries such as Germany and Japan.
Galvanized steel wire rope includes hot dip galvanizing and electro-galvanizing, with thick zinc layer and thin electro-galvanizing layer. Stainless steel wire rope, which is twisted with stainless steel wire, is more expensive. Plastic coated steel wire rope. The smooth steel wire rope produced for 180 years will be replaced by phosphating coated steel wire rope.
If steel wire rope is mainly used, according to the structure, diameter and strength grade of steel wire rope, the minimum breaking force can be found in GB89 18 standard, and the bearing capacity of steel wire rope can be divided by the safety factor.
Extended data:
The main function of the rope core is to support the wire rope and realize a stable cross-sectional structure. The rope core includes a steel core and a fiber core, and the fiber core includes natural fiber cores such as sisal, jute and cotton thread, and synthetic fiber cores including polyethylene and polypropylene filaments. Natural fiber core can store more grease, lubricate steel wire rope and prolong its service life.
During the twisting process of steel wire rope, spraying grease has two main functions, one is to lubricate the steel wire rope to slow down the wear of the steel wire rope surface, the other is to isolate the steel wire rope surface from oxygen in the air and inhibit the oxidation and corrosion of the steel wire rope.
