seizing wire galvanized

Barbed wire welding is the reason for the occurrence of black spots is because the welding wire action to be timely in the melting time, development should be appropriate, no argon, long time burning, current, distance, tungsten needle blunt, molten pool temperature is high, is the root cause of blackening. Continuous burning, is about the active welding machine energy selection, machine welding will appear black spots.

In the rolling process, if the surface of the steel wire is rough, the relative friction coefficient of the steel wire and roll increases, the friction resistance increases, the steel wire elongation decreases, the width increases. In the production of weighted leather material is easy to wide, is because of its rough surface. On the contrary, the surface of the steel wire is smooth, because the friction resistance between the steel wire and the roll is small, it is easy to extend, and the width is small. Domestic steel wire in order to prevent rust, the surface coated with butter, such as butter removal is not clean, easy to slip when rolled flat, also affect its width.

3, whether positive and negative twist, whether the need for bilateral silk.

Hot dip galvanizing is in the hot melt zinc liquid dip plating, production speed, thick but uneven coating, the market allows the low thickness of 45 microns, up to 300 microns above. It is dark in color, consumes more zinc metal, forms infiltration layer with base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environment.

Annealed wire is a soft iron wire made of low carbon steel cold drawing, heating, constant temperature, heat preservation and other processes. The composition of iron wire varies according to its use. It contains iron, cobalt, nickel, copper, carbon, zinc, and other elements. The hot metal billet rolled into 6.5mm thick steel bar is the wire rod, and then put it into the wire drawing device into a different diameter of the line, and gradually reduce the aperture of the wire tray, cooling, annealing, plating and other processing technology made of various specifications of iron wire.

1. Adjust electroplating process parameters

These citizens, who love the subway, rely on it and enjoy its speed, often like to call themselves the U-pin price. Is widely used in industry, agriculture, farming, construction, transportation and other welded wire mesh is used in the field of high quality low carbon wire line of welding and become, then after cold, hot dip plating, PVC plastic coated surface passivation, such as plasticizing processing, production of metal mesh with smooth surface, uniform mesh, solder joint is firm, stability, corrosion resistance, good corrosion resistance characteristics. The U nail price is made of high quality stainless steel wire row welding; For example, machine protective cover, animal animal fence, flower fence, window guard bar, channel fence, poultry cage and home office food basket, paper basket and decorative articles, more acid, alkali, welding firm, beautiful and other characteristics.

Large roll galvanized wire is processed from high quality low carbon steel wire rod. Each wire rod rolled by continuous rolling mill is not less than 200kg, but 15% of the number of plates in each batch is allowed to be composed of two, of which the weight of each rod is not less than 80kg, and 4% of the number of plates in each batch is allowed, and the mass of its single wire rod is less than 200kg, but not less than 40kg. Each rod rolled by semicontinuous mill shall not be less than 60kg, and each batch shall be allowed to have 5% disk nitrogen. The mass of the rod shall not be less than 60kg, but not less than 30kg.

With the development of mining industry, pig iron classification in Our country has been very extensive, can satisfy the demand of machinery industry. In general, iron used to produce large coils of galvanized wire can be divided into two classes. A metal produced directly from iron ore and iron smelting, consisting of iron oxide, silicon dioxide, and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed in, so that the refined material is called general pig iron, is also for the initial grade of the material.

Regular maintenance and maintenance, save a lot of time, but also save the cost of maintenance and maintenance. With good stability, good corrosion resistance, greatly prolong the service life. More kinds, can be selected according to different uses, making annealing wire device is simple, improve the utilization rate of the device.

Generally, due to wet weather and more precipitation, oxidation and rust of binding iron wire NetEase occurs, so we should better store and use galvanized iron wire to avoid rust as far as possible. About the barbed wire, the surface of the barbed wire attached a layer of galvanized layer, the galvanized layer if too thick will not meet the SGS environmental standards. But if it is too thin, it is easy to oxidize with water molecules and rust.
