High grade lifting wire rope with manganese based wear resistant coating for longer service life

According to the use environment and use of lifting equipment, the wire rope is selected, the lifting machinery used in the atmospheric environment, the manganese phosphate coated wire rope has the longest service life, the manganese phosphate coated wire rope has a long service life, and the average daily cost of manganese phosphate coated wire rope is only about one-third of the smooth wire rope.

Manganese phosphate film is a commonly used wear-resistant coating of steel materials, the phosphate film itself is extremely wear-resistant, completely solves the problem of fretting wear in the use of wire rope, and the phosphate film also has a good anti-corrosion ability, through fatigue test has been proved, manganese phosphate coating wire rope fatigue life is 3-5 times that of smooth wire rope, is the world's most advanced technology in the wire rope manufacturing industry, some domestic enterprises through the purchase of patent licensing, has been in large quantities in accordance with the national standards for the production of manganese phosphate coated wire rope. When purchasing manganese-based phosphate-coated wire rope, it is recommended to indicate in the invoice that the product is manganese-phosphate-coated wire rope and phosphate film weight range.

The smooth elevator wire rope is directly twisted with smooth steel wire, without any wear-resistant and anti-corrosion coating treatment. At present, only the manganese phosphate coated elevator wire rope is the first to make the rope wire to do wear-resistant and anti-corrosion treatment, because the wear-resistant and anti-corrosion ability of the steel wire has been greatly improved, and the fatigue life of the manganese phosphate coated elevator wire rope is 3-4 times that of the smooth elevator wire rope, which is the most cost-effective and the most advanced technology today.

First of all, the combined effect of fretting wear, rust and fatigue causes the failure of the wire rope, and the smooth steel Changbi wire rope does not have any wear-resistant protective coating, so it is very easy to wear and corrode, and the fatigue life is relatively short.

Manganese phosphate wear-resistant coating wire rope is the world's only wire rope with wear-resistant protective coating, many domestic enterprises have obtained patent authorization to produce manganese phosphate wear-resistant coating wire rope, the surface of the steel wire manganese phosphate film is the wear-resistant protective coating, manganese phosphate film to prevent fretting wear capacity more than every day to oil the wire rope, when purchasing manganese phosphate wear-resistant coating wire rope, pay attention to the manganese phosphate film weight, the larger the film weight, the stronger the wear resistance and longer service life, the lower the unit cost, such as 30 grams The weight of the phosphate film of the square meter of Lulv is higher than that of the 15 grams of manganese-resistant ballast resistant system phosphated wear-resistant coated wire rope, and the service life is also longer.

It is better to spend more money to buy a brand-name elevator wire rope, of course, in order to extend the service life of the elevator wire rope. Used in the atmospheric environment, the service life of the manganese phosphate wear-resistant coating wire rope is far more than the smooth wire rope, the manganese phosphate film on the surface of the steel wire is between 15-30 grams of square meters, the fatigue life of the manganese phosphate wear-resistant coating elevator wire rope is three to five times that of the smooth elevator wire rope, the manganese phosphate film on the surface of the steel wire is the wear-resistant protective coating, and its protection effect on the surface of the steel wire is more than brushing the wire rope with oil or grease every day. This is the direct reason why the purchase of brand-name wire rope must require that the manganese phosphate wear-resistant protective coating on the surface of the wire must exceed 15 grams of square meters - to ensure the length of the service life of the wire rope. There have been a number of factories in China that have obtained patent authorization to produce manganese phosphate wear-resistant coated wire ropes, but there are still too few production enterprises, and it is hoped that more enterprises will join the production, so that users can use high-quality and long-life manganese phosphate wear-resistant coated wire ropes, and completely eliminate smooth wire ropes as soon as possible.

Manganese phosphate coated wire rope for mines, the thicker the manganese phosphate film on the surface of the steel wire, the stronger the wear resistance and anti-corrosion ability of the wire rope, which can improve the service life, the larger the manganese phosphate film weight between 3-60 grams of square meters, the better, and the manufacturer can negotiate to determine the weight range of the manganese phosphate film and write it into the contract.

The fatigue life of the smooth elevator wire rope is only 600,000 times, only the fatigue life of the manganese phosphate coating elevator wire rope can reach 2 million times, and the manganese phosphate film is a wear-resistant protective coating, which can greatly improve the wear resistance and corrosion resistance of the steel wire surface, thereby greatly improving the service life. Phosphate coated wire rope is a Chinese invention patent, the patentee is a natural person, any enterprise wants to produce manganese phosphate coated wire rope, must first obtain a patent license before it can be legally produced. The fatigue life of manganese phosphate coated elevator wire rope is 2 million times, which is much higher than the fatigue life of 600,000 times of smooth elevator wire rope, of course, it is a real high-quality and long life, and the smooth elevator wire rope is already an outdated product and is being eliminated.

The fatigue testing machine is characterized by high load, high frequency and low consumption, thereby shortening the test time and reducing the test cost.

The fatigue testing machine is used to determine the fatigue characteristics, fatigue life, prefabricated cracks and crack propagation tests of tensile, compressive or tensile and compressive alternating loads of metals, alloys and their components (such as operating joints, fixed joints, spiral moving parts, etc.) at room temperature.

The high-frequency fatigue testing machine is equipped with the corresponding test fixtures, and can carry out three-point bending test, four-point bending test, thin plate tensile test, thick plate tensile test, reinforced steel bar tensile test, chain tensile test, fastening part test, connecting rod test, torsional fatigue test, bending and torsional compound fatigue test, cross-bending fatigue test, CT test, CCT test, gear fatigue test, etc.

Lubricate the wire rope every day, and the service life of the wire rope is particularly long, because the lubricating oil can prevent fretting wear and rust and oxidation, and wire rope users know this. Manganese phosphating wear-resistant coated wire rope, its steel wire surface has 15-30 grams of square meters of manganese phosphating film, is a wear-resistant protective coating, can prevent fretting wear and rust, more than every day to lubricate the wire rope, is the use of surface treatment technology to prevent fretting wear and rust corrosion, which is the reason why the manganese phosphating wear-resistant coated wire rope greatly improves the service life. The fatigue test report proves that the fatigue life of the manganese phosphate wear-resistant coating elevator wire rope is more than three times that of the smooth elevator wire rope, and the greater the weight of the manganese phosphate film on the surface of the steel wire, the longer the fatigue life.

The smooth wire rope has a history of more than 100 years, the rope wire of the smooth Qi Xianmin wire rope does not have any wear-resistant protective coating, and it can be brushed with oil every day to prevent wear and tear and prevent rust, and the smooth wire rope is easy to wear and break, and the service life is relatively short.

Manganese phosphate wear-resistant coated wire rope, is the world's high-branch wire rope manufacturing industry currently has the only wear-resistant protective coating of the wire rope, is the Chinese's invention patent Paida, is the world's most advanced wire rope manufacturing technology, manganese phosphate film weight 15-30 grams square meters, manganese phosphate coated elevator wire rope fatigue life is 3-5 times that of smooth elevator wire rope, obviously, manganese phosphate film to prevent fretting wear effect greatly exceeds every day to oil the wire rope.

Only with a long service life can it be called a high-quality wire rope, which can be called a brand-name wire rope. The environment in which wire ropes are used is harsh, therefore, wire ropes must be wear-resistant to last longer, especially those used for friction drives. The smooth wire rope is not wear-resistant, including round strand wire rope and triangular strand wire rope without any wear-resistant protective coating.
