Hot dip galvanizing is also called hot dip zinc and hot dip galvanizing: is an effective way of metal corrosion, mainly used in various industries of metal structure facilities. It is to immerse the steel parts after rust removal into the molten zinc liquid at about 500℃, so that the surface of the steel parts is attached with zinc layer, so as to play the purpose of anticorrosion. Hot dip galvanizing process: finished product pickling – washing – adding bath aid – drying – hanging plating – cooling – drug – cleaning – grinding – hot dip galvanizing completion. Hot dip galvanizing is developed from the older method of hot dip galvanizing. It has a history of 140 years since it was applied to industry in France in 1836. However, the hot dip galvanizing industry has been developed on a large scale in the past 30 years with the rapid development of hot dip galvanizing wire.
- (6) Save transportation costs. It can be reduced into small rolls, and involved in moisture-proof paper packaging, occupying little space.

Post time: 15-07-22The first is the cost of raw materials galvanized sheet and galvanized wire, some specifications and waste calculation and so on. Then there is the cost of mechanical processing process and manual processing process. Finally, there is the cost of packing and shipping. In recent years, due to the rapid development of thorn rope manufacturers, so the profit margin of blade thorn rope is not particularly broad.
Domestic iron wire factory has been able to consume wire rope, radial low steel wire, umbrella steel wire, spring steel wire, bicycle saddle spring steel wire and other products. In the 1980s, hot – plated low carbon steel wire, fan net cover steel wire, carbon structure steel wire, bed steel wire and so on were also published. The elongation of wire is increased after annealing. Make the product more soft and increase the scope of application of the wire.
1, galvanized wire mesh molding sheet must be packed with flat hard data, to avoid eternal deformation due to poor packaging. It IS VERY IMPORTANT THAT EACH PACKAGE AND ROLL OF RAW SHEET MATERIAL BE MARKED WITH PRODUCT NAME, STANDARD, QUANTITY, TRADEMARK, batch number, MANUFACTURER, DATE of production, STACKING SYMBOL, INSPECTOR CODE AND INSPECTION CERTIFICATE.
Post time: 08-07-22Stainless steel barbed rope in the way of corrosion is not very, because the surface is not treated but rely on its own raw materials for corrosion resistance, so there will be no chemical reaction.
4. Keep the rinsing water clean after wire pickling, which is an important link to reduce zinc consumption. The management system of the rinsing water after the steel wire pickling should be regularly and regularly discharged after the rinsing water, and the rinsing water should be kept clean and low acid value as far as possible. The pH control is more appropriate.
Large rolls of galvanized wire in oxygen violently extinguished, spark, and sodium block, magnesium strip in oxygen extinguished, no spark phenomenon. This phenomenon is determined by the composition of galvanized wire. The galvanized wire used in the experiment is pig iron or steel wire, pig iron and steel are iron and carbon alloy, containing iron and carbon two elements of complex material. Carbon in galvanized wire will produce carbon dioxide when extinguished, solid into gas, volume will shrink rapidly.
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.

Some customers pay more attention to the quality problem, so they pay more attention to the service life. The barbed rope factory will generally recommend the use of high zinc barbed rope or stainless steel barbed rope.

- The management system of the rinsing water after wire pickling should be discharged regularly and regularly, and the rinsing water should be kept clean and low acid value as far as possible. It is more appropriate to control the pH value of 3. The concentration of plating aid should not be too high. The hot plating wire must be added with ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled within the range of 50~80g/L. If ammonium chloride or zinc chloride is added without reference to the results of laboratory analysis, it should be criticized and educated, and economic treatment should be given if necessary.
Post time: 22-12-22Welding electrode has a wide range of applications, can realize a variety of materials, a variety of profiles and a variety of joint forms of welding.
- In what aspects is the uniformity of galvanized wire reflected:
Post time: 11-04-23We must have a certain understanding of the hexagonal net, we are swayed by the beautiful shape of the hexagonal net, not only the shape of the hexagonal net is very beautiful, in fact, the practical value of survival is very high. The relevant information of Shaojie should be very clear to know that the high speed road guardrail network, hexagonal mesh of all kinds of guardrail network, the value of the high speed road is more prominent, it is not only used in a variety of roads, in a variety of sports ball venues and landslides to take care of, but also to reach the very close utility.
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.

Post time: 23-11-22- Wire mesh is the iron screen with high corrosion resistance, the same is also one of the iron net class of widely used net class, its efficient corrosion resistance function in breeding industry, construction industry and other aspects are much liked. Its smooth and neat net surface, not only increased their aesthetic feeling, but also can play a certain decoration effect.
- Similar to two materials in the coating part melting together, and coating thickness can reach 100 microns, so high corrosion resistance, salt spray test 96h no problem, equivalent to 10 years under the usual environment; Cold galvanizing is electroplating at room temperature. Although the thickness of the coating can also be controlled, the binding strength and thickness of the coating are relatively low, so the corrosion resistance is poor.

Post time: 19-07-22After proper heat treatment or cold drawing hardening, high carbon steel wire has high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is acceptable, but welding function and cold plastic deformation ability is poor.
Stainless steel blade barbed rope production process is basically similar to galvanized blade barbed rope production process, usually according to the mold to determine the size of the blade.
