If the surface of galvanized wire is black and the galvanized layer is thin and uneven, the galvanized wire is partly because the inventory storage time is longer, but also because the production technical requirements of galvanized wire do not meet the standard and lead to the quality problems of galvanized wire. According to the use of galvanized wire is different, galvanized wire has soft and hard, then the galvanized wire used for binding requires the flexibility of galvanized wire is better, the flexibility of galvanized wire is good, and it can be easy for workers to operate.
The formation process of hot dip galvanized layer is the process of forming iron-zinc alloy between the iron matrix and the outside pure zinc layer. The surface of the workpiece forms the iron-zinc alloy layer during the hot dip plating, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc solution, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the gravitational attraction between the atoms is relatively small.
Hot dip galvanized hexagonal net is made of low carbon steel wire by mechanized braided welding and then by hot dip zinc treatment. The net color is white and shiny, thick zinc layer, uniform mesh, flat mesh surface, solder joint tension resistance, high corrosion resistance. The surface of the steel wire is usually protected by hot-dip galvanizing, and the thickness of the galvanized protective layer can be made according to the requirements of customers. Hot-dip galvanizing hexagonal net is another kind of twisting mesh corresponding to the galvanizing hexagonal net.
We 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 introduction of the relevant information should be very clear to know 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 a very close utility.
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.
Cattle net in the outdoor use of a long time will inevitably show rust corrosion, this time the use of cattle net life depends on the maintenance of the product is not in place, we all know that cattle net if long exposure to harsh environment, the service life will be greatly reduced. How long does a normal cattle net last?
Pet cage has many types, and selective is bigger, pet cages are generally made of wire, with better coarse, then at the bottom with a wheel base, such a simple pet basket was made, in the wheel at the bottom of the mount is for the convenience of the mobile, a pet cages should also adapt to the location of the production in addition to a door, Convenient in pet feeding when more convenient.
With the development of mining industry, the classification of pig iron is already very broad in our country, which can satisfy the demand of mechanical industry. In general, the iron used to produce large rolls of galvanized wire can be divided into two classes. A metal exercised directly from the iron ore through the iron making stroke, the composition of the ore is iron oxide, silica and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed into it. The material produced in this way is called ordinary pig iron, which is also the material for the first grade.
Hexagonal mesh is a metal wire woven Angle mesh (hexagonal) made of wire mesh, the use of metal wire diameter is based on the size of the hexagonal and different. Also known as: twist flower net, stone cage net, gabion net, flood control network.
Large roll galvanized wire is processed by low carbon steel wire rod, through drawing molding, pickling rust removal, high temperature annealing, cooling and other processes. Large roll galvanized wire electroplating temperature should be controlled in 30-50℃. Because of the strong corrosivity of chloride ions in bath, quartz glass heater is generally used. Continuous production does not need heating, but need cooling cooling.
