Question 1: What is the steel wire of the steel wire rope? According to the different materials of wire rope core, it can be divided into hemp rope, wire rope, natural fiber wire rope and synthetic fiber wire rope. It has excellent corrosion resistance. Hemp core steel wire rope is often used in lifting operation, and the hemp core is soaked with lubricating oil to reduce the friction between strands and steel wire and prevent corrosion.

According to the number of strands and wires of steel wire rope, it can be divided into 6× 19, 6×37 and 6×6 1. The most commonly used wire ropes are 6× 19 and 6×37.

According to the different surface treatment of steel wire, it can be divided into smooth wire rope and plated bowl. Smooth steel wire ropes are often used in lifting operations.

According to the strand structure of steel wire rope, it can be divided into point contact rope, line contact rope and surface contact rope.

Except the central steel wire, each layer of point contact rope has the same diameter, and the strands are twisted in layers, and the steel wires cross each other to form point contact, so the contact stress is great when working, and the steel wires are easy to wear and break.

The wire contact stranded wire is formed by twisting steel wires with different diameters at one time. The steel wires in the steel strand are different in thickness, so the thin steel wire is placed in the groove of the thick steel wire, and the thick steel wire is in contact with the thick steel wire. Because the line contact wire rope is relatively dense, the breaking force of the wire rope with the same diameter is greater. The wire rope rotating in the same direction with the same diameter of the steel wire in the strand is also a line contact rope.

The inner steel wire of the surface contact rope has a special shape, and adopts special-shaped cross-section steel wire, and the steel wire is in surface contact. Its advantages are smooth appearance, good corrosion resistance and wear resistance, and being able to bear large lateral force. But it is expensive and can only be used in special occasions.

Special-shaped strand wire rope: Special-shaped strand wire rope is named because its strand section is triangular, elliptical or fan-shaped.

Galvanized steel wire rope: a steel wire rope made by galvanizing (or drawing after galvanizing) and twisting.

Steel wire rope can be divided into circular strand wire rope and irregular strand wire rope according to the form of strand section (mainly including triangular strand wire rope, elliptical strand wire rope and fan-shaped strand wire rope). According to the surface state of steel wire (wire rope), wire rope can be divided into smooth wire rope, galvanized (zinc-aluminum alloy) wire rope and plastic-coated wire rope.

Question 2: Is the wire rope made of Q235? Not necessarily. Mainly depends on what kind of wire rope you are. Have you hoisted the rope? What is its diameter? If it is used for hoisting, it is definitely not q235, and its strength is too small. Domestic steel wire ropes are generally 45#, 60#, 70# and 80#.

Question 3: Does the steel wire rope belong to the category of metal materials? Metal materials are divided into ferrous metals and nonferrous metals. Billet belongs to ferrous metal. Copper and copper alloys, aluminum and aluminum alloys are all nonferrous metals.

Question 4: What kind of material does the wire rope belong to financially? It depends on whether it is used in products or as a tool. If used in products, it belongs to raw materials, and if used as tools, it belongs to low-value consumables.

Question 5: What kind of material does the important steel wire rope belong to? Mainly depends on the occasion of wire rope use, such as whether it is used as a product or as a tool. If it is used in products, it belongs to raw materials (such as steel wire ropes for building decoration), and as a tool, it belongs to low-value consumables (elevators and other uses). Steel wire rope for important use in coal mine belongs to low-value consumables.

Question 6: What are the material properties of wire rope in finite element analysis? It should be a flexible part.

At present, the finite element method is used to analyze the wire rope, or to analyze the stress state of the wire rope, so as to find out the weak point of the wire rope. There are many papers in these areas, and I feel useless. There is a simple reason. Even if the stress analysis of wire rope is clear, what methods can reduce or change the stress of wire rope? There is not much room for improvement in the structure of wire rope.

The following paper is novel in conception, and advocates that the service life of steel wire rope can be improved by wear-resistant phosphating treatment of steel wire. The related problems of producing manganese phosphating coated steel wire rope, fretting fatigue and protective measures of hoisting steel wire rope, failure process of steel wire rope and principle analysis of prolonging its service life are discussed. These things may be the development trend of wire rope industry, which can be downloaded from paper net for reference only.

Question 7: What is the main material of wire rope? Thank you. Wire ropes can be divided into ordinary wire ropes and stainless steel wire ropes according to raw materials, among which stainless steel wire ropes are different according to different stainless steel materials.

Question 8: What material is the steel wire? I can't help but see the answer. Why don't you say it's made up of stirrups and gangs? Steel wire is generally high carbon steel, that is, carbon structural steel with carbon content of 0.60% and 0.7%.

Question 9: What is the material of light and hard steel wire rope? Generally, steel wire ropes made of SWRH82A or SWRH90A have high strength and light weight.
