The tensile strength of cold drawn spring steel wire is slightly higher than that of oil tempered steel wire. The large specification of cold drawn steel wire elastic force is too large, winding the spring is very difficult, so the cold drawn spring steel wire application specification is generally less than 8.0mm, oil quenching tempered steel wire application specification is generally less than 13.0mm. In fact, the diameter of 13.0mm spring is used to light tension spring steel wire, cold drawing wound made into shape and then quenched and tempered. Steel wire with diameter above 15.0mm is mostly made by heating winding process.

The interlocking system also allows deductions for easy attachment control.
Galvanized wire mesh is divided into hot dip galvanized wire mesh and cold galvanized wire mesh. Galvanized steel wire net selects the high quality low carbon steel wire, iron wire factory made by precision of automation machinery welding technology processing, smooth surface, firm structure, integrity is strong, even if the local cutting of galvanized steel wire net, or local also under pressure from loose phenomenon, after molding, wire mesh galvanized corrosion resistance good, has the advantage that the general steel mesh does not have.
Three methods of twisting the thorn rope: forward twisting, reverse twisting, reverse twisting.
Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Solid particles or excessive foreign metal impurities in the electroplating solution can cause such problems. Solution: If the coating of large galvanized wire is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.
Galvanized hexagonal mesh features: easy to use; Save transportation costs. It can be reduced into small rolls, and involved in moisture-proof paper packaging, occupying little space. Coating thickness uniformity, corrosion resistance is stronger; Simple construction, no special technology; Strong resistance to natural damage and corrosion resistance and the ability to resist adverse climate impact; Can withstand a wide range of deformation and still not collapse. Play the role of fixed heat preservation and insulation.
- Two: the color of the spray blade is beautiful and generous, and the color can be selected according to the use environment to integrate it with the surrounding environment. Plastic colors include grass green, dark green, black, red, white and so on.
1. Eliminate caked zinc residue on zinc liquid surface
Unless it is a specially customized model, the stainless steel blade barbed rope produced now is generally produced with a 22mm blade length mold, which is what we usually call bto-22 type. It doesn’t have to be the case that there are specifications from 11mm to 65mm. Unless the customer insists on customizing the specified length, the barbed rope manufacturer produces bto-22 stainless steel blade barbed rope.
The duration of the protective effect of galvanized layer on large roll galvanized wire is closely related to the coating thickness. Generally speaking, in the dry main gas and indoor use, the thickness of galvanized layer only 6-12μm, and in the environment is more severe conditions, galvanized layer thickness needs 20μm “to be up to 50μm”. Therefore, the influence of environment should be considered when choosing the thickness of galvanized layer.
Second: positive and negative twisting rope cost-effective
- Once you find that the beginning of it has deformation, rust or broken problems must be timely correction. Generally speaking, the blade barbed rope will not be damaged simply, but it cannot be ensured that it will not happen. Because the local place where the blade barbed rope is required is generally outdoors, the probability of presenting an incident will be greatly increased. For example, in the plantation under the hillside, the blade barbed rope was damaged and deformed by stones rolling down the mountain, which requires manual correction in time, otherwise the deformed blade barbed rope will not only affect the beauty, but also lay hidden dangers for safety.
3. Acid activation acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts, without excessive corrosion on the matrix.
The large roll of galvanized silk should be coated with oil, the fiber core is dipped in oil, and the grease should be able to protect the fiber core from decay and corrosion, the iron wire moistens the fiber, and lubricates the wire rope from the inside. The surface is coated with oil so that all the wire surface in the rope strand is evenly coated with a layer of anti-rust lubricating grease, which is used for the mine rope with friction lifting and mineral water, to be coated with black grease with increased wear and strong water resistance. Other uses are coated with red oil oil with strong film and good rust resistance, and require it to have a thin oil layer, which is easy to keep clean during the operation.
According to the galvanized iron wire manufacturer, galvanized iron wire is the selection of excellent low carbon steel, through drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized, cooling and other processes. Galvanized iron wire should pay attention to the following points in the use process:
Electric galvanized shaft wire direct selling is in the plating tank through the current unidirectional zinc gradually plated on the metal appearance, the 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 hot dip galvanizing, the production cost of electric galvanizing is lower. The difference between cold galvanizing and hot galvanizing: the difference between cold galvanizing and hot galvanizing is that the amount of zinc is different. They can be identified from the color. The color of cold galvanizing is shiny silver white with yellow. Hot dip galvanizing shiny white.
- The policy of wire mesh mesh size, wire, square meter steel content, galvanized amount, etc., to consider the corrosion resistance of wire mesh ability and system safety! Wire mesh galvanized is more fierce than the wire diameter, galvanized is very important, must be hot plating, welding after plating is better than the first plating after welding, as for wire diameter, inductive consideration of site construction and meet the needs of safety.
- Core diameter: according to customer requirements (mm)

Post time: 24-10-22The production process of large rolls of galvanized wire is a level of drawing, through the mold into a slightly smaller diameter than the original. And so on down to the desired length. One pull is not desirable, must be numbered, from coarse to fine is dependent on metal ductility. If it changes too much it just breaks. After drawing to a certain diameter, galvanized, so that the finished product.
Post time: 20-04-23With the development of mining industry, pig iron classification in Our country has been very extensive, to meet the needs of the machinery industry. Generally speaking, iron wire factory produces galvanized iron wire iron can be divided into two categories, is directly from the iron ore through iron tracing exercise out of the metal, the primary components of the ore is iron oxide, silica and other miscellaneous stones. When this ore is specially refined into metal iron, the elements such as carbon, silicon, manganese and so on are mixed in, so that the refined data is called – like general pig iron, also for the initial grade of the material.
