For example, in gray iron, its carbon exists in iron ore in the form of graphite, the crack is often gray, soft and tough, simple filter cutting, suitable for casting. In the white iron, the carbon and iron are combined to form iron carbide, the crack appears white, the quality is very strong and brittle, and it is the material of malleable steel. Alloying grade is composed of various alloying elements with different composition and structure.
Dog cage mainly by welding, spraying, injection molding, surface treatment, electroplating dog cage is made of high quality steel wire, dog cages are with plastic and plastic surface treatment, electrophoresis, chrome plating, galvanized, imitation gold, etc., according to the customer request processing, respectively, also can be customized to sample, dog cage assembly of compact structure, neat and beautiful appearance, make folding and remove the cage is more convenient and quick, won’t take up too much space.
1. Simple grid structure, beautiful and practical; 2. Easy to transport, installation is not limited by terrain ups and downs; 3. Especially strong adaptability to mountainous, sloping and multi-curved areas; 4. The price is medium and low, suitable for large area. Main market: railway, highway closed network, field fence, district guardrail, all kinds of isolation network.
Heavy hexagonal mesh is made of steel wire woven into hexagonal mesh by special machinery. This kind of mesh, after cutting and assembling, can be made into fence mesh, mountain hanging mesh, vegetation three-dimensional mesh, assembly, etc. Alias: gabion mesh, heavy hexagonal mesh, ecological mesh, wire mesh, etc.
Welding mesh is also known as external wall insulation wire mesh, galvanized wire mesh, galvanized welding mesh, wire mesh, row welding mesh, touch welding mesh, construction mesh, external wall insulation mesh, decorative mesh, barbed wire, square eye mesh, screen mesh, anti-crack mesh. Stainless steel welding net, is made of high quality stainless steel wire row welding, more acid resistance, alkali resistance, solid welding, beautiful, wide use and so on.
Dog cage mainly by welding, spraying, injection molding, surface treatment, electroplating dog cage is made of high quality steel wire, dog cages are with plastic and plastic surface treatment, electrophoresis, chrome plating, galvanized, imitation gold, etc., according to the customer request processing, respectively, also can be customized to sample, dog cage assembly of compact structure, neat and beautiful appearance, make folding and remove the cage is more convenient and quick, won’t take up too much space.
Therefore, when the zinc reaches saturation in the solid melt, the two elements of zinc and iron atoms are diffused with each other, and the zinc atoms diffused into (or infiltrated into) the iron matrix migrate in the lattice of the matrix and gradually form an alloy with the iron, while the iron diffused into the molten zinc liquid forms an intermetallic compound FeZn13 with the zinc and sinks into the bottom of the hot galvanized pot, that is, zinc slag. When the workpiece is removed from the zinc leaching solution, the surface of the pure zinc layer is formed, which is hexagonal crystal, and its iron content is not more than 0.003%.
Titanium alloy with low carbon content is obtained because the carbon content remains the original concentration. The hardness of titanium alloy is mainly related to its carbon content. Therefore, after carburizing and subsequent heat treatment, the workpiece can obtain the performance of hard and tough inside. Galvanized wire varieties are mainly classified into three categories: electric galvanized wire, hot galvanized wire and galvanized wire. Among them, the classification of galvanized wire is divided into large roll galvanized wire, medium roll galvanized wire, small roll galvanized wire, galvanized shaft wire, truncated galvanized wire and other main production varieties.
Steel wire after galvanized treatment, the surface will be covered with a layer of zinc metal, to play the role of anti-corrosion, anti-fouling, enhance strength and beauty. The galvanized wire drawing treatment is to process the steel wire by stretching method to obtain a finer, higher strength and smoother surface, and improve its mechanical properties. However, will wire drawing affect the electrical conductivity of galvanized steel wire?
The large hexagonal mesh is called the stone cage net. Stone cage net before delivery, must be folded into a simple surface, packed compressed after delivery. Then put it in the right position to open, and then the block diameter suitable stone into the cage, the cover is tight, and then the various stone cage net and the adjacent stone cage net tied up.
There is no adhesion test of powder spraying or fluorocarbon spraying on packaged galvanized wire, but there are two points for reference: first, in sealed or air-free environment, non-metallic volatiles can corrode zinc coating; Second, zinc at higher than 230 degrees (c) will cause the matrix metal brittle. And powder spraying and fluorocarbon spraying are to be baked at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in coating adhesion decline, and even lead to (matrix) steel wire brittle situation may exist.
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. Galvanized iron wire has good anti-corrosion and anti-rust ability, so it can be prevented from being used in some outdoor guardrail or fence, especially on handicrafts, handicrafts are also of great use, galvanized iron wire, the surface is not easy to rust and oxidation.
