Because the anti-aging and anti-corrosion ability of zinc-aluminum alloy wire is much higher than galvanized barbed rope, it is widely used in all kinds of places where personnel are scarce and lack of maintenance ability, and is used for island protection in coastal areas
The temperature of large roll galvanized wire should be controlled at 30 to 50℃ during electroplating. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used. Continuous production does not need heating, but needs cooling. Cooling can be in the groove side row thin wall plastic pipe, through the flow of tap water cooling, can also be used as a titanium pipe temperature control device.
The antisepsis of these materials is very different, the use of life is not the same. Cold galvanized cattle net, also known as electroplating, galvanized amount is small, rust in rain, but the price is cheap, the service life is 5-6 years. The amount of zinc on hot dip galvanizing (low zinc and high zinc) is about 60g to 400g, the service life is about 20-60 years, and the corrosion resistance is general.
In order to improve the corrosion resistance of steel pipe, the general steel pipe is galvanized. Galvanized steel pipe is divided into hot dip galvanized and electric galvanized. The layer of hot dip galvanized is thick, the cost of electric galvanized is low, and the surface is not very smooth. Used for steel blowing oxygen pipe, generally with small diameter welded steel pipe, specifications from 3/8-2 inches of eight. Made of 08, 10, 15, 20 or 195-Q235 steel strip, in order to prevent corrosion, some should be aluminized.
After the optimization of the process, mass production of 0.80mm electro galvanized steel wire electro galvanized zinc layer quality is controlled within 80 ~ 90g/m2, zinc layer quality dispersion is very small; The results show that the average weight of zinc layer is 14.5g/m2, the loss of zinc layer is less than 5%, and the tensile strength of steel wire is 2300 ~ 2500MPa. It not only effectively controls the quality of zinc layer of raw steel wire, but also reduces unnecessary waste and production cost.
Wire rod to stop normalizing or soxaustenitizing treatment, large specifications with spheroidizing annealing instead. In the middle, especially before the waste product drawing process of thermal disposal throughout the selection of soxaustenitizing disposal. Decarbonization should be prevented during thermal disposal. Sulfuric acid or hydrochloric acid pickling was used to remove the oxide sheet after hot treatment. Coating (see lubrication carrier) can be dipped in lime, phosphating, borax disposal or copper plating.

The common specifications of small hexagonal net in production are: the width is 1.22m, and the commonly used width is generally 1m. In terms of length, the small hexagonal net basically has no limitation. 1-100 meters can be produced. The production diameter of small hexagonal mesh is generally No. 27 wire to No. 18 wire, and the aperture size is 0.95cm-5.08cm.
Widely used in mining, petroleum, chemical industry, construction, mechanical accessories, protective net, packaging net, barbecue net, barbecue oven net, sintering furnace net, hardware products with net, hardware products with net, arts and crafts with net, vibrating screen net, net basket, food machinery with net, barbecue with net, wall net, grain with net, highway, railway, infrastructure with net.
Broken wire is the iron bright wire, fire wire, galvanized wire, plastic coated wire, paint wire and other metal wire, wire factory according to customer requirements for straightening after sizing cut, has the characteristics of easy transportation, easy to use, widely used in the construction industry, handicrafts, daily civilian and other fields. No limit on length, packing as required. Annealing wire also known as black oiled wire, black annealing wire, fire wire, black iron wire. Compared with cold drawing, black annealed wire is more economical as raw material for nails.
There are many important details that need to be paid special attention to during the production of barbed rope or blade barbed rope by the barbed rope factory. If any improper, it will cause unnecessary losses.
There is good toughness and elasticity, simply put, can be easily made into various shapes, and zinc as a coating is silver, very beautiful. Such characteristics make hot dip galvanized wire handicrafts, woven screen and other aspects have also been applied. Hot plating wire selection of high quality low carbon steel rod processing, is the selection of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, cooling and other processes.
Hardness is a commonly used property index in mechanical properties of metal materials. The iron wire factory introduces a fast and economical test method for hardness testing. However, for the hardness of metal materials, there is not a unified and clear definition including all test methods at home and abroad. In general, the hardness of a metal is often considered to be the resistance of the material to plastic deformation, scratches, wear, or cutting.
Barbed rope manufacturers specializing in galvanized barbed rope, hot dip galvanized barbed rope, blade barbed rope, stainless steel barbed rope, plastic coated barbed rope, positive and negative twisted barbed rope production for ten years.
Enclosure to calculate the use of barbed rope, so as to reasonably plan to purchase the amount of barbed rope to facilitate construction.
The material of the blade can be roughly divided into high quality steel wire, galvanized steel plate, stainless steel plate. The general technology used on the blade: hot dip galvanizing – stamping. The blade has the advantages of corrosion resistance, aging resistance, good weather resistance, easy installation, low price and so on. The use of blade rope: Blade rope has been widely used in military sites, prisons, government, banks, residences, private homes, villas, doors and Windows, roads, railway fences and border lines, etc., to ensure safety. Most prisons basically use razor blades.

Three methods of twisting the thorn rope: forward twisting, reverse twisting, reverse twisting.
The tensile strength of steel wire is high and the hardness is high. In the flattening process, the longitudinal movement resistance of steel wire per unit volume increases and the elongation decreases. The steel wire unit volume will move to the lateral resistance smaller, the width of the increase. On the contrary, the wire is easy to extend lengthwise, and its width decreases. This is the production of high steel wire hardness is easy to wide, small hardness, easy to stretch out of wide reasons. If the tensile strength deviation of steel wire is large, the hardness uniformity of steel wire strip is poor, the width difference of the billet rolled into large, will seriously affect the quality of the billet.
Because they are afraid of rain, there is no need to say more about this, and the surface packaging is more afraid of sun, so it is not recommended to prevent outdoor exposure to sunlight, which will lead to the loss of the woven bag, resulting in the internal blade barbed wire exposed to affect the later use.
5, play; Appreciation and pan touch. Light touch, over time, the cage will naturally precipitate the traces of time and history and vicissitudes of life. This process does not affect the normal use of the cage. However, it is necessary to maintain the cage continuously and not to use it to the end.
2. Dissolution treatment: Put the pickling steel wire into the dissolution tank, and dissolve the zinc powder with the bath liquid by heating, and the dissolved zinc liquid will adhere to the surface of the steel wire.
The wire mesh is composed of low carbon steel wire or medium carbon steel wire, high carbon steel wire or stainless steel wire. There are two kinds of manufacturing technology of steel wire mesh, one is the weaving method, the other is the welding connection, the formation of grid.
