The wire rod should be normalized or soxhlet processed, instead of spheroidal annealing for standard large ones. Soxhlet process is widely used in the heat treatment of the center, especially the products before drawing. Avoid decarbonization during heat treatment. After heat treatment, sulfuric acid or hydrochloric acid pickling is used to remove iron sheet. The coating (see smooth carrier) can be dip-lime, phosphating, borax treatment or copper plating.

When laying steel wire mesh, according to the laying method from the middle to both sides in turn. Wall plastering engineering use wire mesh material is generally two kinds: one is electroplating, the other is hot dip galvanized. The former has low cost and a wide range of use. The cost of hot-dip galvanized material is slightly higher than that of electroplating, and the cost is high and the life is good to prevent rust. Hot dip galvanizing is in the case of heating plating. After the zinc is melted into liquid form, the base metal is immersed in it so that the zinc interpenetrates with the base metal and binds so tightly that there are no other impurities or defects left in the process.

Because the large volume of galvanized wire alloy elements in iron ore, can make the copper through the material thickening degree of strengthening, hardness, impact force, strength resistance, closing rate, elongation, so alloy iron in the exercise of good iron, is an important supplementary element. The difference between galvanized wire and general iron wire is very big, general iron wire is cheap, and because iron is not very stable, easy to rust in wet places, so the stability is not very good, life is not very long.
- Thorn rope used to circle cattle and sheep and other livestock also has one of the biggest features is the price is relatively cheap, for users engaged in the breeding industry, the investment is not small, the use of thorn rope to fence on the one hand is to reduce the cost, on the other hand is the protection effect is better.
- 2, line diameter, mesh spacing (refers to the edge of the twist to the opposite side of the distance).

Poor pretreatment before plating; Bath temperature is too low; Poor quality of additives or too many additives and organic impurities will cause poor bonding. The quality of additives also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the crystal lattice and cause stress, causing the coating to bubble.

- The common specifications of small hexagonal mesh in production are: the width is 1.22m, and the commonly used width is generally 1m. In terms of length, there are basically no restrictions on small hexagonal nets. 1-100 meters can be produced. The production wire diameter of small hexagonal mesh is generally No. 27 wire to No. 18 wire, and the aperture size is 0.95cm-5.08cm.

Galvanized wire coating is galvanized, aluminum plated, coated with nylon or plastic, etc. Zinc is divided into thin coating of steel wire after plating and thick coating of galvanized steel wire after drawing. The mechanical properties of thick coating are reduced compared with smooth steel wire rope, which should be used in severe corrosion environment. It is more resistant to corrosion, wear and heat than galvanized wire rope, using the first plating and then drawing method of production. Coated nylon or plastic wire rope is divided into two kinds of coated rope and coated stock after the rope.

Because of the high carbon content, simple cracks occur during water quenching, so double liquid quenching (water quenching + oil cooling) is mostly used, and oil quenching is mostly used for small cross section parts. This type of steel is generally used after quenching by medium temperature tempering or normalizing or in the surface quenching state. Mainly used for manufacturing spring and wear-resistant parts.

For the barbed rope products produced by the barbed rope factory, the number of rotating turns between the two thorns is usually 3-5. What is the internal relationship between this and the length of use?
-
The error of construction welding net diameter should be controlled at 0.02 mm. For example, we buy wire diameter of 89 wire welding net, with a micrometer to measure the diameter, the diameter of the allowable range is 87 -91 wire. In this range is qualified welding net. Because the accuracy has been compared, but no one can control it so well in the production process. The welding net can be accurate to 0.01 mm, so the error is allowed.
-
The corrosion or discoloration of galvanized iron wire in the atmosphere caused by oxygen, moisture and other pollution impurities is called rust or rust. After galvanized iron wire rusting, it will affect the appearance quality, seriously affect the use, and even cause scrap, so galvanized iron wire must be properly kept and pay attention to rust prevention.

Barbed rope is an isolation protective net made of iron wire, which is wound on the main line (twisted wire) through the winding machine and through various weaving processes. Thorn rope generally has three methods of twisting, the following Haorong for you to introduce in detail.
- The form of installation: in the top with the various cage tied together at least as wrapped stone cage net that combination closely not easy to use bad. If the local bandaging is appropriate, it can increase the stability of the structure. There are a lot of grid edge, if the stone cage net only hook in the cage edge and not prepared in the cage edge, even in loose.
-
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.

Post time: 14-06-24 - It helps to dissipate heat. Building grid (floor heating) has good thermal conductivity and heat dissipation, the appearance of heat dissipation effect is more average 2 cm, 2.5 cm, 5 cm, 10 cm, 15 cm, 20 cm. Wire rope thickness, net length, net width, mesh and other indicators can be stopped at any time according to customer request. The mesh, solder joints, and mesh are all equal.
- 2, the cage must be strong
- The new weaving machine can weave 3.5m wide, 5cm narrow, can be customized according to customer requirements.
- The cleaning agent used for cleaning has no effect on the adhesion of the coating and no corrosion on the base material. Acid activation Acid activation solution should be able to remove corrosion products and oxide film from the surface of parts without excessive corrosion of the matrix. Zinc plating may be zinc plated with zincate or chloride and appropriate additives shall be used to obtain a coating that meets the requirements of this standard. After light plating, light treatment is carried out. Passivated parts requiring hydrogen removal shall be passivated after hydrogen removal. Activation with 1% H2SO4 or 1% hydrochloric acid for 5 ~ 15s prior to passivation.

The characteristics of this kind of small animal cage, is small, light, easy to carry, but also easy to clean care. For small animal cages, 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 “violent”, or the cage under the “destruction” will occur welding or plastic crack off.
- The structure of the hook mesh is essentially permeable to air and water, which has a strong tolerance for the natural effect and filtration effect of groundwater. The suspended matter and silt in the water can be piled up in the rock filling joint and applied in mountain protection, which is conducive to the growth of natural plants and beautify the grass spray to reach the curing effect of their own in the later period. The gradual restoration of the original ecological environment is a perfect connection between beautification and protection.
- 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.
