Large rolls of galvanized silk play a very important role in our life. Made of low carbon steel rod processing, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling and other process processes. Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire). Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.
- Carbon spring steel wire current national and occupational recommendation specifications are divided into two types: one is cold deformation steel wire, also known as cold tension spring steel wire. Cold drawn carbon spring steel wire is first quenched by lead to obtain soxhlet arrangement, and then the surface phosphating, with a large surface reduction rate drawn to the finished scale, the steel wire arrangement is fibrous, has high tensile strength and elastic limit, good winding and change function.

In GENERAL, THE HARDNESS OF A METAL IS OFTEN CONSIDERED AS THE RESISTANCE OF a MATERIAL TO COMPRESSION PLASTIC deformation, scratches, wear, or cutting. In the adjustment of zinc dip distance of galvanized wire, keep the original speed unchanged, according to the time of zinc dip, wire diameter, and then estimate the zinc dip distance. By adjusting the zinc dipping distance, the zinc dipping time of various specifications of steel wire is shortened by 5s on average compared with that before debugging, so that the zinc consumption is reduced, the zinc consumption per ton of steel wire is reduced from the original 61kg to 59.4kg.
- 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.

Select cut silk first to ensure that the raw material of the silk is exactly the raw material you need, the raw material will be used well. Choose high straightness, so that the length of the truncation will be the same, will not show a lot of length difference, the length of the truncated wire is a very important element to choose the truncated wire.
- 5, after the light plating should be carried out light treatment.

Railway is not only the main artery of national economy, but also an important means of mass transportation to protect people’s travel. It plays an important role in the process of economic and social development. Therefore, the safety issue is an important guarantee for railway transportation, one is a symbol of the railway transportation enterprise product quality, the other is also the focus of social attention. The off-road collision accident is one of the focus of public opinion on the railway industry. How to grasp the off-road safety management, eliminate the off-road collision accident from the source, maximize the protection of people’s life and property safety, and reduce the non-operational cost of railway enterprises is a key content of railway safety work in the new era. We should install protective nets on both sides of the railway, which are also barbed wire protective nets, so as to prevent accidents.
- Hook mesh from the point of view of weaving quality inspection requirements, hook mesh wire and silk staggered can not loose, the whole piece of hook mesh can not loose deformation. Of course, if the customer special requirements out of the net, showing loose phenomenon can not blame the production side. Whether the mesh meets the specification requirements and the wire diameter meets the wire diameter.
- Steel wire mesh is finished by fine welding of active welding equipment. The material can be divided into cold wire drawing, hot dip galvanizing, cold galvanizing, dip plastic, etc. To be used for bridge reinforcement, bridge deck pavement, building reinforcement, etc.
- 4. When the dog is tired or nervous, it can enjoy its own private space in the cage and let it have a good rest.

Did not do the adhesion test of powder spraying or fluorocarbon spray on the packaging galvanized wire, but there are two points for reference: one, in the sealed or air circulation environment, non-metallic volatiles can corrosion zinc coating; Second, zinc above 230 degrees (c) will brittle the base metal. After powder spraying and fluorocarbon spraying, it is necessary to bake at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in decreased adhesion of coating, and even leading to brittle situation of steel wire.

Removal of surface-active substances by activated carbon matting. Or make the bubble unstable according to overworry, these are all reasonable countermeasures; Other strategies should also be used to minimize the amount of surfactant taken in. The introduction of organic matter can make the electroplating process speed drop sharply. Galvanized iron wire blackening can be effectively prevented, such as: the work site to keep dry, reduce and do not use chemicals, operators with clean gloves and so on. In addition, hot dipping zinc factory can be required, after dipping zinc must be passivation treatment, passivation treatment of zinc has a better anti-discoloration effect, can effectively prolong the discoloration time, the combination of the two, discoloration should be able to solve. Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.

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:
-
Some customers are more concerned about quality problems, so for the service life is more important, barbed rope factory will generally recommend the use of high zinc barbed rope or stainless steel barbed rope.
- The top of the wall is installed with ordinary galvanized barbed rope for protection. Although the effect is better, the style is not beautiful. In recent years, it has been gradually replaced by blade barbed rope. First of all, the protection ability itself does not have any point of emphasis, can not use its own climbing at the same time, due to the relatively large volume of the intention to turn over the personnel caused no small difficulty, the whole body has a spike is very easy to be scratched or hook clothes, so in this aspect of the protection ability is better. Moreover, the style of spiral cross is more beautiful than the original single style, which is more suitable for some high-grade apartments and other external walls of the fence, at the same time, it will not cause the feeling of imprisonment in the interior.

With the development of mining industry, the classification of pig iron is already very broad in our country, which can satisfy the demand of mechanical industry. In general, the iron used to produce large rolls of galvanized wire can be divided into two classes. A metal exercised directly from the iron ore through the iron making stroke, the composition of the ore is iron oxide, silica and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed into it. The material produced in this way is called ordinary pig iron, which is also the material for the first grade.

The characteristics of these cages are small, light, easy to carry and easy to clean. For small animal cage, the wire diameter of the general iron wire is not very large, the thickness of the plastic is relatively thin, so the use of the time can not be “violence”, otherwise the cage in the “destruction” will occur under the welding or plastic crack.

Large roll galvanized wire is made of low carbon steel wire rod processing, is made of low carbon steel, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling and other surface treatment process processing. Large roll galvanized wire is divided into hot dip galvanized wire and cold galvanized wire (electric galvanized wire). Although galvanized galvanized wire and silver powder paint spray effect appearance is not much different. But the effect is very different, galvanized wire surface is zinc layer, good adhesion, good corrosion resistance.
