Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Electroplating solution with solid particles or excessive foreign metal impurities, will lead to such problems. Solution: If the large roll galvanized wire to the above coating is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.

The life of the “wire”, is actually “low carbon steel wire”, carbon content in less than 0.2%. The surface is usually coated with zinc plating because it is easy to rust. Under atmospheric conditions, the galvanized layer will not rust before most of the fall off, relatively soft. The life of the “steel wire”, is carbon content in about 0.6% of the “carbon steel wire”, or carbon content in about 0.8% of the “high carbon steel wire”, they have enough hardness and elasticity after appropriate heat treatment, high strength. Uses such as winding ordinary spring and so on.

Enclosure to calculate the use of barbed rope, so as to reasonably plan to purchase the amount of barbed rope to facilitate construction.
- The drawing process of the product drawing process has a great influence on the product function. Generally, a large total surface reduction rate of about 90% (see area reduction rate) and a small pass surface reduction rate (about less than 23%) are selected to ensure the endurance of the product. On the high strength spring steel wire, drawing should control the exit temperature of each passage of the steel wire is lower than 150℃, to avoid the steel wire due to strain aging and appear to change the crack, which is the formation of steel wire scrap the primary disadvantage.

Due to the influence of production process or other factors, the zinc layer of galvanized wire products will be different to a certain extent, especially ordinary galvanized can not reach the beauty of electric galvanized, ordinary galvanized wire zinc layer is mainly for anticorrosion and corrosion prevention. Large volume galvanized wire products refers to the use of high quality low carbon steel, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized, cooling and other processes, some galvanized wire products are made of iron wire galvanized.

Iron products are common metal products in life. Iron products appear everywhere in our life, but there is a big problem in using iron products. Iron products will rust, and when rust occurs, it will affect the use and appearance of iron products. Adding non-metallic coating: clean, dry and coat the surface of iron and steel products with a layer of protective materials, such as oil, mineral grease, rust-proof grease, plastic and lacquer.
- In this temperature range, the zinc solution is severely corroded to the workpiece and the zinc pot, and the iron is lost at 560 degrees Celsius to add obviously, and the zinc will be the iron substrate above 660 degrees Celsius, zinc slag will be added quickly, plating cannot be used. Therefore, electroplating is carried out in the range of 430~450 degrees Celsius.

Different from the general zinc barbed rope, high zinc barbed rope surface zinc content is very high can reach the former 6-8 times, so in the service life also has a great advantage, ordinary products three or five years began to corrosion and the latter will take longer to change. Stainless steel barbed rope is in the material aspect of protection, so the durability is also better, these two products are long in the service life, but in the price is high.
-
Post time: 02-03-23 - If the requirements are higher, and it is humid place, it is recommended to use hot-dip galvanized barbed rope, although the price is higher, but the service life is longer, generally speaking, it is more cost-effective.

With the increasingly extensive use of hook mesh, the method of bridge rail is also different. The height of sidewalks or seatbelt outer railings should not be lower than 1.10 metres. The net distance between railings should not be greater than 140 mm and horizontal bar rails should not be used. The planning of the hook mesh is necessary to be safe and reliable, the bolt should be installed on the basis of the railing, its strength should meet the requirements of the standard.

The production process of large rolls of galvanized wire is a level of drawing, through the mold into a slightly smaller diameter than the original. And so on down to the desired length. One pull is not desirable, must be numbered, from coarse to fine is dependent on metal ductility. If it changes too much it just breaks. After drawing to a certain diameter, galvanized, so that the finished product.

The main difference between the two is the carbon content. The carbon content of iron is 2.11 percent or greater, while the carbon content of steel is 2.11 percent or less. The iron carbon alloy with carbon content above 2.11% is cast iron (pig iron), which is basically not malleable and cannot be drawn into wire. Secondly, the content of impurities is different. The content of harmful impurities such as sulfur and phosphorus in steel is smaller. Steel wire general color focus, iron wire color light point, white point.

Cold drawing wire is a metal cold processing, with wire rod as raw material, that is, the mouth of the steel bar. Cold drawing wire is a product produced by a series of processes such as shell stripping, which is a common wire. In the development and production of metal materials, cold drawing wire is a very common material, its performance is good, the range of use is very wide, manufacturers in processing are the use of cold processing to produce.

Every galvanized wire production into the peak season of the industry, the road to the factory will from time to time see transportation wire and container container vehicles, as well as galvanized bright silk short-distance transportation trucks, led to the utilization of labor in the surrounding countryside, solved the employment problem of most people. Galvanized wire is divided into hot plating wire and cold plating wire.
-
Most people in addition to pay attention to the price of barbed rope, many people for hot-dip galvanized barbed rope or cold galvanized barbed rope will have questions, in fact, these two products, the price difference is not very big, so how to choose hot-dip galvanized barbed rope and electric galvanized barbed rope?

Now it is more used in the binding of the construction industry. Compared with ordinary wire, it is also softer and has better luster. Use in daily life does not need to carry out maintenance and maintenance, saving a lot of time, but also save the cost of maintenance and maintenance. Annealed wire has good stability, good corrosion resistance, greatly prolonging the service life. There are many kinds, which can be selected according to different uses. The device for making annealed wire is simple, and the utilization rate of the device is improved. The material properties of annealed wire can meet different processing needs.
- Generally, galvanized wire used for welding is required to have a certain hardness. After acceptance of galvanized wire, the first thing to do is to feel the hand, and the other thing is to test on the machine. Because the average user does not have testing equipment, it is also very inconvenient to test on the machine. Use a micrometer to measure the diameter of galvanized wire evenly, and keep it about 0.02mm above and below the contract signing standard, with neat appearance, no leakage plating and no mess.
-
Many customers are in great need of galvanized barbed rope when they decide to purchase it, and the barbed rope specification determines the length of the later installation.
- (3) Can realize butt joint, Angle joint, lap joint, T joint and other joint forms of welding.

So, do you know how to pick the right dog cage? When choosing a dog cage, focus on quality and practicality! Let’s take a look at it:
-
Traditional barbed wire is woven into wire, with the development of the economy, the rapid rise of all walks of life, the limitations of the use of traditional barbed wire gradually exposed, such as: aquaculture, to the chicken circle a cage can not be too dense, the wire can not be too thick, woven mesh wire once the mesh over the surface of the net will become soft. We also have the solutions: 1, rolling the straight wire into a wavy shape, but still not enough to feed chickens with mesh can only stretch out the chicken beak can not feed! 2, is electric welding mesh, with the current to the longitude and latitude of the wire spot welding together, mesh do more than most is not restricted.
- Choose a cage with a reasonable structure, such as a tray under the cage, so that the dog can relieve itself directly inside the cage. It’s easy for the owner to clean up.
