  • Deoxygenation of boiling steel is incomplete, oxygen content is high, phosphorus and other impurities distribution is uneven, local overspending, aging sensitivity and cold brittle sensitivity are high, hot cracking tendency is added. If unqualified electrode is used, if the content of carbon and sulfur in the weld metal is too high, cracks will occur. For example, when factories use acidic electrodes to weld Q235-A steel, the high carbon fernoganese in the electrode coating will lead to thermal cracks in the weld.
  • If the requirements are higher, and it is humid place, it is recommended to use hot-dip galvanized barbed rope, although the price is higher, but the service life is longer, generally speaking, it is more cost-effective.

  • For the specification of galvanized wire, the galvanized wire produced by our factory can range from No.8 to No.22, which refers to the BWG standard, that is, from about 4mm to 0.7mm, which can basically cover the type required by customers. As for the raw material of galvanized wire, normally, we use Q195 mild steel, and some factories will also use SAE1006 or SAE1008. The following is the zinc coating, for galvanized wire, this thing is more important, the general zinc coating is about 50g/m2 to 80g/m2, some customers need high zinc galvanized wire, zinc coating can reach 200g/m2 to 360g/m2. The tensile strength of galvanized wire is usually 350n/m2 to 800n/m2. Then there is the packaging specification of galvanized wire. The specifications of small rolls of galvanized wire are 50kg/ roll, 100kg/ roll and 200kg/ roll. Of course, there are large rolls of galvanized silk, the weight can reach 300kg/ roll or 800kg/ roll.

  • Excellent anticorrosive makes its popularity in the feed, the net surface smooth and tidy, increased the look and feel, can be adornment effect, this characteristic makes it to show in the mining industry, due to high quality with low carbon materials as raw materials, to make it unique general iron mesh screen does not have flexibility, determine its plasticity in use process, Thus can be used in the hardware process of deep processing and manufacturing, complex wall batch swing, underground leakage prevention cracking, light mesh body, so that the cost is much lower than the cost of iron screen, more able to understand its economic and practical.

  • (3) anti-freezing, residential protection, landscaping protection;
  • Scope of use: Because the obtained coating is thicker, hot-dip galvanizing has very good protective function than electric galvanizing, so it is an important maintenance coating for iron and steel parts in strict working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding and other occupations. In agriculture, such as pesticide irrigation, greenhouse and construction industry, such as water and gas transportation, wire casing, scaffolding, Bridges, highway guardrail and other aspects, have been widely used in these years.

  • 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.

  • When pickling, the galvanized wire needs to be slowly put into the cylinder to avoid liquid splashing on the body. Protective glasses should be worn in the pickling process to prevent acid splash out and hurt people. Pay attention to safety when receiving the line operation, the line tray needs to be lightly placed, stacked neatly, not more than 5 disks. No matter what kind of auxiliary materials are used, galvanized wire drawing must comply with national regulations, otherwise it is not allowed to be used.

  • 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.

  • 6, according to the wire diameter thickness to adjust zinc dipping time. Zinc dipping time should be adjusted according to the thickness of wire diameter. The method of adjustment is the length of the distance between the lead screw on the zinc pot and the ceramic sinking roll. The zinc dipping time of coarse wire diameter should be long, and the zinc dipping time of fine wire diameter should be short.

  • The mixture of rare earth and aluminum enhances the fluidity of zinc liquid, makes the coating more uniform, and also reduces the zinc consumption. Hot dip galvanized wire has better protection performance than cold galvanized wire, which makes it good application in chemical experimental equipment. Hot dip wire coating thicker, 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 dip galvanized wire is widely used in construction, traffic guardrail and other outdoor facilities.

  • Under normal circumstances, the organic matter contained in galvanized wire can make electroplating speed significantly reduced. Although chemical formulations facilitate high deposition rates, the deposition of organic matter does not meet the requirements of coating thickness, so activated carbon can be used to treat the bath.

  • The electrode is a kind of material that the coating (that is, the coating) is uniformly and centrally applied on the welding core outside the metal welding core. The electrode is composed of two parts: the welding core and the coating. The welding core is the metal core of the electrode. In order to ensure the quality and performance of the weld, there are strict regulations on the content of various metal elements in the welding core.

  • After the corrosion of impregnated hexagonal wire mesh, the original characteristics will be lost, and the shape, color and mechanical properties will be changed, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break and lose the original protection function. Usually, there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment is easier to rust than dry environment, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the corrosion of impregnated six-sided wire mesh, prolong the service life of the product.
