Post time: 30-08-22- First, cold galvanized wire production process before treatment. Before galvanizing, a series of pre-treatment work on the steel wire is required, mainly including pickling, dissolution and brine or alkali washing.
Our country industry chooses the low carbon steel with good quality as raw material, and then produces the quality galvanized iron wire by drawing, galvanizing and other processes. Now the production technology of galvanized iron wire products can be divided into hot plating and electroplating two kinds of methods. No matter which one is chosen, it should be carried out in accordance with the corresponding operating specifications, so as to better ensure the production of good products. For key and important parts with tensile strength greater than 1034mpa before plating, the stress should be released at 200±10℃ for more than 1 hour and 140±10℃ before plating.
Galvanized iron wire will rust, mainly and the thickness of galvanized layer and the use of the environment, galvanized iron wire is also divided into cold galvanized iron wire and hot galvanized iron wire, in general, hot galvanized iron wire galvanized layer is thicker, rust prevention time is longer, generally can be 7 or 8 years without rust. If the galvanized layer is damaged, or long-term use in a humid environment, it will accelerate the rust time of galvanized iron wire.
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.
Large coil galvanized wire in the zinc immersion distance debugging, keep the original speed unchanged, according to t= KD to determine the zinc immersion time (1), where: t is the zinc immersion time is constant, take 4-7D is the diameter of steel wire mm, and then estimate the zinc immersion distance. By adjusting the zinc dip distance, the zinc dip time of steel wire of various specifications can be shortened by 5s on average. In this way, the zinc consumption per ton of steel wire decreases from 61kg to 59.4kg.
- The patented technology is used to regularly put zinc blocks into the plating aid pool, so that the bivalent iron in the plating aid becomes trivalent iron, and plays an important measure to stabilize the PH value within a numerical range, and also facilitate the filter to filter out the trivalent iron ions in the plating aid; The trivalent iron ion is controlled between 0.3 and 1.0g/L; When hydrogen is not released in the plating aid, the zinc block is continued. It is an effective measure to reduce zinc slag, improve the fluidity of zinc liquid and reduce the thickness of zinc layer to give full play to the function of plating aid filter.
Two, the production process is different
- Hongyu twist flower hexagonal mesh factory is the selection of low carbon steel silk woven, mesh structure he has the characteristics of corrosion resistance, high strength and ductility. Steel wire diameter up to 2.0mm-4.0mm, steel wire appearance is usually selected hot dip galvanized maintenance, galvanized maintenance layer thickness can be made according to customer needs, galvanized maximum can reach 300g/㎡.
Now most people want to choose a few when choosing barbed wire material better thorn rope, but the special barbed wire the better, not right, it is important to choose which model is most suited to their own thorn rope,, although is very simple product, but in the use of these products are for specific situation is different, and has a different effect, Maybe now consumers do not have too much concept of blade barbed rope, in fact, such barbed rope products have a higher safety factor.
- 6. It’s easy for your dog to get used to a strange place as long as it has a home he’s familiar with, so you can take your dog on a trip instead of leaving him at home.
Stainless steel barbed wire is mainly used in the place near the sea more, wet salty air for metal corrosion is particularly serious, and the selection of stainless steel barbed wire is in order to prevent corrosion.
- Attention should be paid to line collection and operation. Others shall not get on the train without the monitor’s consent. The wire reel should be put lightly, stacked firmly and neatly, not more than 5 discs. It is forbidden to contact human skin directly with acid and base. When the acid fog exceeds the specified target of the state, timely measures should be taken to control it; otherwise, production is not allowed.
- According to the habit often according to the basic galvanized hardware before plating treatment method, as long as it does not contact with water can keep 5~7 years or so without rust, of course, if it is a salt water test, it will not be over 4 hours. Hot dip zinc is to use zinc tin solution to cover the hardware, and the rust prevention time is about five times that of traditional galvanizing. The general outdoor construction is to use hot dip zinc, and the salt water test can do about 36 hours.
- The middle of the two thorns is 7 to 8 circles, while the ordinary thorn rope is only 3 and a half circles, showing neat and beautiful.

- It helps to dissipate heat. Building grid (floor heating) has good thermal conductivity and heat dissipation, the appearance of heat dissipation effect is more average 2 cm, 2.5 cm, 5 cm, 10 cm, 15 cm, 20 cm. Wire rope thickness, net length, net width, mesh and other indicators can be stopped at any time according to customer request. The mesh surface, solder joint and mesh are all equal.
- Knitting mesh number: according to customer requirements
They are good at expressing unspoken feelings to people. Their owners feel respect, dependence, admiration and affection. The process of caring for pets inspires people’s sense of responsibility, brings more meaning to people’s life, and helps people establish the fulcrum of life and confidence in life. In fact, dogs are very malleable animals. Through scientific and rational training, you can become a popular family member.
After annealing, iron wire will become softer and more flexible. Iron is a more active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements in dry air, its production cost is low, the use and scale is relatively wide, better protective function, so it is an important material for steel parts used in strict working environment.
Post time: 08-05-23Pet cage is generally made of high quality iron wire, low carbon steel wire, stainless steel wire welding, which is characterized by beautiful, lightweight, folding, easy to store. The surface treatment of pet cage is generally: cold galvanized, hot galvanized, spray, dip, chromium plating, nickel plating and other methods.
Post time: 27-10-22Strictly control the pH value of large roll galvanized wire bath, research shows that the size of the bath pH value directly affects the quality of steel wire coating, improper control of pH value will cause loose coating. When the pH value is greater than 3, the steel wire coating has burr caused by fine dendrites, and the surface is not smooth. The current density is strictly controlled. From the microscopic morphology, the higher the current density, the larger the zinc layer grain deposition, the less dense the corresponding zinc layer.
There are many kinds of galvanized solution, which can be divided into cyanide plating solution and cyanide plating solution. Cyanide galvanizing solution has good dispersion and covering ability, coating crystallization is smooth and fine, simple operation, wide application range, has been used in production for a long time. However, because the plating solution contains highly toxic cyanide, the gas escaping in the plating process is harmful to the health of workers, and the waste water must be treated strictly before discharge.
