During this process, each time the wire is pulled over, the surface hardens due to the high friction temperature. So basically every time you pull it you have to annealing it in the furnace. On the one hand, it is to reduce the surface hardness. On the other hand, during the process of wire pulling, only the surface is deformed, and the center is unchanged. So there’s a lot of stress inside. Therefore, it is necessary to rely on annealing to eliminate the internal stress, so that the wire becomes soft again to eliminate the stress before being drawn again.

- Annealing is to restore the plasticity of wire, improve the tensile strength of wire, hardness, elastic limit, etc., the wire after annealing is called annealing wire. In the production process of annealing wire, it is very important to ensure the quality of the finished wire, make the wire have certain strength and suitable degree of soft and hard. The annealing temperature is between 800 ℃ and 850℃, and the length of furnace tube is lengthened appropriately for enough holding time.
- Copper sulfate point test is a simple way to quickly distinguish ordinary carbon steel and all types of stainless steel wire rope. The concentration of copper sulfate solution used is 5%-10%. Before the point test, the experimental area should be thoroughly removed from the oil or other impurities, and a small area should be polished by grinding machine or soft grinding cloth, and then the test liquid drops to the grinding place. Ordinary carbon steel or iron in a few seconds will form a layer of outer metal copper, and the surface of stainless steel does not produce copper precipitation or display copper color.
Stainless steel barbed rope according to the different categories of nickel applications are not the same, in the dry indoor environment using 304 stainless steel effect is quite good. However, in both rural and urban areas, to maintain its appearance outdoors, it is necessary to stop washing frequently. In heavily polluted industrial areas and coastal areas, the surface will be so dirty that it will rust. But to achieve aesthetic effect in outdoor environment, it is necessary to use nickel stainless steel. Therefore, 304 stainless steel is commonly used for curtain wall, side wall, roof and other building uses, but in the corrosive industrial or Marine atmosphere, it is best to use 316 stainless steel.
After passivation treatment of galvanized layer, a layer of bright old and beautiful color passivation film can be generated, which can significantly improve its protective performance. There are many kinds of galvanized solution, which can be divided into cyanide plating solution and cyanide plating solution. Cyanide galvanizing solution has good dispersion and covering ability, coating crystallization is smooth and fine, simple operation, wide application range, has been used in production for a long time.

Some customers are more concerned about the quality of the problem, so for the service life is more important, thorn rope factory will generally recommend the use of high zinc thorn rope or stainless steel thorn rope.
Hot dip galvanized hexagonal net is made of low carbon steel wire by mechanized braided welding and then by hot dip zinc treatment. The net color is white and shiny, thick zinc layer, uniform mesh, flat mesh surface, solder joint tension resistance, high corrosion resistance. The surface of the steel wire is usually protected by hot-dip galvanizing, and the thickness of the galvanized protective layer can be made according to the requirements of customers. Hot-dip galvanizing hexagonal net is another kind of twisting mesh corresponding to the galvanizing hexagonal net.
Steel wire mesh by its own unique advantages in construction occupation, reinforcement anti-crack occupation is indispensable reinforcement anti-crack data, high product error is small, mesh mesh uniform, welding firm, strong acceptance, not easy to deformation, steel wire mesh in different fields have different called, in bridge engineering construction people call it soft reinforcement.
The cat cage is novel in shape, exquisitely crafted, exquisite in materials, luxurious and generous, and is an ideal choice for you to raise pet cats. Generally, high-quality steel wire is selected, and the surface is treated by spraying, dipping, chrome plating, galvanizing, and imitation gold. Cats have become an extremely widespread pet in families all over the world. There are fat pads on the bottom of their toes, so they walk silently. When catching mice, they will not startle them, and have sharp nails on the toes.
- Good word of mouth blade barbed rope must be a reasonable evaluation given by consumers after using, this is because many people feel good after choosing the blade barbed rope, whether in terms of safety protection or in the overall decoration and beautification effect is very good, so that in the actual choice will be more assured, In the eyes of many people, the high quality razor cord will not have problems, or the overall service life is really long, so that we can reduce a lot of cost, and can know whether it is the best.
- 1. Water washing: Clean the galvanized steel wire to remove the residual zinc liquid and impurities on the surface.
- 2.25*2.25mm means that the two strands are 2.25mm silk, and the barbed wire is also 2.25mm silk;
Post time: 19-08-22- Especially after passivation of galvanized layer, the surface of the oxide layer is thicker and compact, itself has high oxidation resistance. On the other hand, when the surface of the galvanized layer is damaged, exposing the inner iron matrix, because zinc is more active than iron, zinc will bear the role of sacrificing zinc anode, zinc will be oxidized before iron, so as to protect the iron layer will not be damaged.
Stainless steel wire is characterized by good corrosion, in chemical plants or pharmaceutical industry can often be used to stainless steel wire, suitable for acid, alkali environment. Aluminum alloy wire is characterized by high temperature, can adhere to the high temperature of more than 100 degrees Celsius does not fade, and has good corrosion, patience is also very good. It can be used for device manufacturing in construction industry.
The size of the galvanized layer of galvanized iron wire is related to the anti-corrosion ability and application effect of galvanized wire. The thickness of the galvanized layer of the general standard galvanized wire products should be tested after the product is formed. There are three specific test methods. Weighing method and cross section microscopy method are destructive experimental methods, and magnetic method is a relatively rigorous non-destructive method, but the measurement steps and requirements are relatively high, so they are rarely used in specific applications. The first two methods are intuitive and common methods.
