What is special steel wire rope? What are the characteristics of special steel wire rope?

What is special steel wire rope? For the word "special steel wire rope", everyone should know that steel wire rope is divided into two categories: ordinary steel wire rope and special steel wire rope. Ordinary steel wire rope is 6*7, 6*19 and 6*37 of the pointing contact series. Special steel wire rope is divided into wire contact steel wire rope, surface contact steel wire rope, multi-layer non rotating steel wire rope, surface contact multi-layer non rotating steel wire rope, triangle strand steel wire rope and anti twist steel wire rope. The company mainly divides special steel wire rope into six categories.

Special wire rope

Class I: wire contact wire rope: 6*19s, 6*19w, 6*25fi, 6*36sw, 6*55sw. There are two main forms of wire contact wire rope, Xilu type and valenton type. This kind of wire rope called Xilu type and valenton type is developed abroad and has been popularized abroad. However, in China, many users do not understand why it is so expensive to carry two letters and why the words "Xilu type" and "valenton type" are so expensive. In fact, it is a very simple principle, The main function of the line contact and filling type is to minimize the fatigue operation of the internal formula of the steel wire rope. The specific explanation: when the steel wire rope passes through the pulley, there is no gap between the steel wire and the steel wire due to the combination of thick and thin wires, so it is not easy to be bent. However, there is a gap between the steel wire and the steel wire in the ordinary point contact steel wire rope. When the steel wire rope passes through the pulley, it will be bent, operated back and forth, and the fatigue wire will be broken, The inner strands of steel wires also rub against each other, resulting in fatigue and broken wires.

Class II: elevator wire rope and basket wire rope: 8*19s, 8*25fi, 4*19s, 4*25fi

Class III: surface contact wire rope: 6k*36sw, 6k*25fi, 6*k31sw, which is generally used for domestic pile drivers and rotary drilling rigs

Class IV: multi strand non rotating steel wire rope: 18*7, 19*7, 24w*7, 35w*7.18*7 is the most popular, tower crane, crane, gantry crane (gantry crane), electric hoist, traveling crane

Class V: multilayer strand surface contact wire rope: 18*7k, 24w*7k, 35w*7k.

Category VI: Triangle strand wire rope and sealing wire rope: 6v*39s, 6v*48s, 4v*39s, 4v*48s. Z-shaped steel wire rope and sealed steel wire rope are mainly used for cableway and tank way.

Special wire rope

The special steel wire rope is characterized by higher fatigue resistance, higher breaking tensile strength and better wear resistance than the point contact steel wire rope with the same diameter. Because the tensile cross-sectional area of special steel wire rope is large, and the precision between strands and between wires is large, the probability of fatigue wire breaking should be greatly reduced, and a large cross-sectional area will strengthen the tensile force. As far as the special steel wire rope itself is concerned, it is a high-end product, and its service life is longer than that of ordinary steel wire rope. For our users, the price performance of special steel wire rope is better. It seems that the price of special steel wire rope with the same diameter is much higher than that of ordinary steel wire rope, but the service life of special steel wire rope is far longer than that of ordinary steel wire rope. This ratio far exceeds the price. That is to say, as long as special steel wire rope is used, I believe that the cost of using steel wire rope will be saved every year. In addition, the replacement times of steel wire rope will be reduced, the labor intensity of workers will be reduced, and the damage of steel wire rope to mechanical equipment will be reduced. In terms of social environmental protection, the use of special steel wire rope also plays a positive role. Because the steel wire rope industry is an industry with high energy consumption and high pollution, and the electricity consumption per ton of steel wire rope is more than 500 degrees, the use of special steel wire rope as much as possible also responds to our national policy of energy conservation, emission reduction and environmental protection. We lisen special steel wire rope focus on the production of high-quality special steel wire rope. Lisen people use their life energy to do higher, better and stronger special steel wire rope to provide high-quality steel wire rope for our steel wire rope users.
