What are the advanced technology of manufacturing wire rope?

In terms of wire rope manufacturing process technology, the so-called advanced, should be the service life of the rope or the production efficiency of a substantial increase in the ability to achieve this standard is only phosphate coating wire rope technology, manganese phosphate coating to improve the abrasion resistance and corrosion resistance, fatigue life of the whole doubled to improve the achievement is remarkable.

China's annual output of 1.8-2 million tons of steel ropes ranked first in the world, phosphate coated steel wire rope is the world's revolutionary innovative technology in the field of steel wire rope, service life (fatigue life) of ultra-large leaps, glossy steel wire rope was completely eliminated, and fully into the era of phosphate-coated steel wire rope:

1.Phosphate-coated steel wire rope (China Patent), manganese or zinc-manganese phosphating treatment, steel wire Surface abrasion, rust and corrosion resistance capacity of the full leap, GB/T11376-1997 metal phosphate conversion film in the national standard on the phosphate film wear, rust role is described in detail, the lubricating grease infiltration of the phosphate film pores to play an exceptionally excellent friction reduction effect, and effectively inhibit the wire rope internal steel wire surface abrasion occurs, is a glossy steel wire rope of the upgraded products, can be used instead of the first plating and then pulling the thin zinc layer of zinc-plated steel wire rope. At present, the fatigue life of the phosphated rope is about 3 times that of the smooth rope, and the best one is 4 times that of the smooth rope, and the fatigue life can be compared with the fatigue test, and the service life can be greatly improved with the in-depth research on the abrasion-resistant phosphating solution later on. Phosphate film 3-60 g / m 2, steel wire phosphating without drawing process, directly twisted wire rope. According to the approximate price of the wire rope market now, manganese phosphate coated wire rope is about 1.4-1.6 times the price of glossy steel wire rope, and the service life extension is much higher than the price of the growth rate, so the phosphate coated steel wire rope daily average cost of use is only 30-45% of the glossy steel wire rope, the use of the cost is lower, more cost-effective

2. galvanized steel wire ropes, including hot-dip galvanized and Galvanized steel wire rope, including hot-dip galvanized and electro-galvanized two kinds, helicoidal hot-dip galvanized steel wire zinc layer is thicker, the thicker the zinc layer is the stronger the corrosion resistance the longer the use of electro-galvanized thinner. Due to the phosphide coating has a certain anti-corrosion properties, manganese phosphide coated steel wire rope can replace some varieties of thin zinc layer galvanized steel wire rope used, such as atmospheric environment but the air humid high-temperature environment, and hot-dip galvanized-phosphide double-coated steel wire rope corrosion resistance is further improved.

3. Stainless steel wire rope, the use of stainless steel wire twisted wire rope, such as 304 or 316 stainless steel, corrosion resistance is higher than the hot-dip galvanized carbon steel wire rope, the price is relatively expensive, the stainless steel wire for manganese phosphating coating treatment (stainless steel wire phosphating requires a special phosphate formula), the same can be a substantial extension of service life.

4. Plastic-coated wire rope, on the basis of steel wire rope, in the steel rope or strand rope outer layer coated with polyethylene, polypropylene.

5. Glossy steel wire rope, the United Kingdom began production in 1834, the domestic 1939 Tianjin First Steel Wire Rope Factory began production (bankruptcy in 2005), with the phosphating coating steel wire rope into the market in large quantities, it will be phosphating coated steel wire rope completely eliminated.

6. Marine engineering mooring ropes, the relevant standards are being developed in the approval process

7. Cable ropes

Atmospheric environment preferred manganese phosphide coated steel wire rope, corrosive environments preferred hot-dip galvanized - phosphide double-coated steel wire ropes, longer service life, lower cost of use.
