Post time: 23-09-22The common weight standard of galvanized barbed rope is 25kg per coil, and the length of each coil varies from 220-250 meters according to the specifications of the barbed rope. And of course we all know that the heavier the disc the longer it is. But there is one point that is worth our attention, that is, the hollow inside the general larger disk is relatively small, and the hollow inside the lighter galvanized thorn rope is relatively large. The purpose of this is to reduce the number of bending of the thorn rope and make it easier and more beautiful when installing, on the other hand, it looks larger in appearance.
If the zinc coating is good, but when the light comes out in 3% nitric acid, there is a dark shadow on the coating, and the film is brown when passivation occurs, which may be caused by foreign metal impurities such as copper or lead in the galvanized liquid. When there is a problem in the process of galvanizing, check the temperature and current density first, and then measure and adjust the content of zinc and sodium hydroxide in the bath through the analysis of the bath. Whether DPE levels are low can be determined by Hull cell test.
Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust. Compared with electrogalvanizing, hot galvanizing has lower production cost and less impact on the environment than electroplating.
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.
In addition, heavy hexagonal net is commonly used in water conservancy projects, as the use of loading stone box, in order to achieve the purpose of river management, floods, in addition to it can also be used as slope prevention, retaining wall, breeding and cherish animals. Small hexagonal net is usually used for animal breeding, wall protection network, green vegetation network and so on.
- Canary cage is also known as hibiscus cage, jade bird cage. Can be made of nickel-plated alloy or bamboo, for the refined round, square or rectangular (breeding cage) bird cage. The top of the cage has two kinds of flat top and dome, and the bottom of the cage is closed with a bottom circle. The circular cage is about 33 cm high and 20 cm in diameter; The square cage is 24.7 cm long, 24.7 cm wide and 33.8 cm high. The spacing of the cage is 1 cm, and the diameter is 0.2 cm. Cage bottom NEED NOT BAMBOO, MAKE IT WITH PLASTIC BOARD, bottom plate CAN move, FACILITATE PULL OUT WASH. Two perches are placed in the cage, and a food and drinking pot is placed in the cage. The cage has a board at the top of the cage to change the bird’s habit of looking up at the sky.
Hot plating wire mixed rare earth and aluminum elements, make zinc liquid fluidity, more uniform coating, but also reduce zinc consumption. Hot-dip galvanized wire has better protective properties than cold galvanized wire, which makes it widely used in chemical experiment equipment. Hot plated wire coating is thick, so that it has good corrosion resistance, can be in the outdoor sun and rain and other harsh environment can be maintained for decades, so hot galvanized wire is widely used in construction, traffic guardrail and other outdoor facilities.
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.
- All can do spring can be called spring steel wire, and high carbon is the highest carbon content. Features: WITH high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is OK, but welding function and cold plastic deformation ability is poor.
Because there are many large livestock in pasture, and because of the large cost of development and easy to be destroyed by livestock, galvanized barbed rope is the best choice for enclosure. Pasture installation thorn rope is necessary, wire mesh factory to introduce the role of pasture installation thorn rope。
Post time: 18-05-22- The drawing process of waste product drawing process has a great influence on product function. Generally, large total surface reduction rate (see area reduction rate) and small pass surface reduction rate (about ≤23%) are selected to ensure the tolerance of products. About high strength spring steel wire, the exit temperature of each pass steel wire should be controlled when drawing below 150℃, to prevent the steel wire from changing cracks due to strain aging, which is the main disadvantage of steel wire obsoletion.
Hot dip galvanized welding mesh is made of iron wire, processed by precision automatic mechanical technology. The mesh surface is smooth, the structure is strong, and the integrity is strong. Even if the local cutting or local pressure is not relaxed, the hot dip zinc is processed. Hot dip galvanized welding mesh surface white color, thick zinc layer, high zinc content at the solder joint, uniform mesh, flat mesh surface, solder joint tensile resistance, high corrosion resistance. It has the advantages that ordinary barbed wire does not have.
- The chromium-plated layer has good thermal property. When the temperature is heated below 500℃, its luster and hardness are not changed obviously. When the temperature is higher than 500℃, the initial oxidation and discoloration occur, and the hardness decreases when the temperature is higher than 700℃. The friction coefficient of chrome coating is small, especially the dry friction coefficient, which is low among all metals. So the chrome coating has good wear.
Wire-wall welding net is widely used in industrial production, agriculture, engineering construction, transportation, mining and other processing and manufacturing industries. Such as machinery and equipment protective cover, animal guardrail, pot flower guardrail, window fence, safety exit guardrail, poultry cage, egg basket and home office food industry basket, paper basket and design decoration. It is suitable for general engineering building wall, pouring concrete, multi-storey building, etc., which plays an important structural role in the thermal insulation system. In the construction of the building, the thermal insulation board of hot-dip galvanized electric welding grid is placed on the inside of the outer mold of the wall to be concreted. The external thermal insulation board and the wall are one kind of live, and the thermal insulation board and the wall are integrated into one body after the removal of the mold. The coating on the surface of the weld core is called the coating. The coating of electrode plays a very important role in the welding process. If the photoelectrode without drug skin is used for welding, in the welding process, oxygen and nitrogen in the air will invade a large number of molten metal, metal iron and beneficial elements such as carbon, silicon, manganese oxidation and nitriding to form various oxides and nitrides, and residual in the weld, resulting in slag inclusion or cracks in the weld. The gas in the weld pool may produce a large number of pores in the weld. These factors can greatly reduce the mechanical properties of the weld and make it brittle.
Galvanized wire is processed from low carbon steel wire rod, after drawing forming, pickling rust removal, high temperature annealing, cooling and other processes. Galvanized wire is widely used. Electroplating temperature should be controlled at 30 to 50℃. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used.
The advantage of galvanized iron wire after annealing: after annealing increases the elongation of the iron wire. Makes the product softer and increases the range of application. After electric galvanizing hot dip galvanizing. Copper electroplating is widely used and screen production. Galvanized iron wire is a soft iron wire product processed by low carbon steel wire through cold drawing, heating, constant temperature, and even heat preservation. Generally, the quality of ordinary galvanized iron wire will be relatively soft, the softness is relatively balanced, and the color is consistent. It is mainly used in construction, mining, chemical industry and so on.
- Hard black galvanized iron wire is made of low carbon steel wire by wire drawing machine. Hard black galvanized iron wire is the first feature of high hardness, bright appearance. It is mainly used for welding clothes hanger, umbrella, metal mesh, basket, basket and other metal products. Soft black galvanized iron wire is made of low carbon steel wire after annealing and softening, and then cold drawing. Soft black galvanized iron wire is the first feature of good flexibility, slightly higher hardness, bright appearance. Mainly used for metal mesh weaving technology, welding net, process products of welding.
Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.
- ③ The galvanized iron wire shall not be damaged when it is tightened.
- 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.
Post time: 06-09-22With a large pickpocket used for steel wire, into the zinc liquid before the surface of the zinc ash stirring; Use a small outlet for galvanized steel wire; Zinc pot steel wire outlet in 30 minutes, with pickpockets back and forth, until the large, floating zinc residue into brown, real zinc ash, zinc ash surface. The extracted zinc ash should be brown yellow real zinc ash, zinc surface, effectively reduce zinc consumption. This is one of the biggest steps to bring zinc consumption down, and it’s a real problem, one that hasn’t been solved for years.
