The type of barbed rope is mainly reflected in the specification of the wire diameter, the thicker the diameter of the barbed rope produced is shorter, at the same time, the price is cheaper, mainly because the production efficiency is relatively high, because the price of the barbed rope is calculated according to the weight when it is sold. On the contrary, the finer the diameter of the wire, the longer the price is higher.

Black iron wire application in the process, the main is through the hot metal billet rolling into six point five mm wire rod, and then put it in the drawing into a line of different diameter, the plant and then gradually narrow drawing plate aperture, cooling and annealing, plating process, such as making a variety of different specifications of the wire, the wire compared with ordinary black iron wire, will be more softer, The softness is also very uniform, the color is consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding hanger, reprocessing industry, etc.

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.

That said, it can always deform by pulling hard without changing its integrity, so cold drawing has usually reached a limit, which is not a problem, because without this property it increases hardness, which is the desired effect. Cold wire drawing encountered more rain, when the climate is wet, easy oxidation and rust. Therefore, in the storage process should pay attention to avoid rust.

Nestor rolling cage, high-speed railway Nestor rolling cage and railway Nestor rolling cage are all produced, sold and installed in accordance with the technical requirements of the reference drawing of railway line 2012-8001. Nestor rolling cage is a kind of protective equipment emerging in railway in recent years. Nestor rolling cage is connected by Nestor connecting clip on the longitudinal tensile rib fixed on the bracket. The longitudinal tension and the support are connected with the Φ2.5mm cold-drawn galvanized steel wire around 2 laps and then tightened. The support is set in the column and the middle of the span of the protective fence of 3m. The other spans are only set with the upper column, and the support and the protective fence are connected with the bracket hoop. For the protective fence that has been installed with metal mesh, the Nestor roller cage is directly fixed on the transverse sheet and wire of the metal mesh with the cold-drawn galvanized steel wire of 2.5mm or the Nestor connection fastener.

The physical methods mainly include manual rust removal and mechanical rust removal, chemical rust removal is generally the use of pickling method, practical application, usually according to the appearance of the workpiece rust status and different post-treatment process, choose different rust removal methods, among which pickling rust cleaning is more commonly used. That is, the iron and steel workpiece with oxide skin or rust is etched in the acid lotion, mainly to remove the oxide or rust layer on the surface of the steel.

Spring steel wire should have high tensile strength, elastic limit, endurance and fatigue strength, and resistance to impact and oscillation. The strength and endurance objectives, especially to prevent the occurrence of modification cracks, are the key to the consumption of spring wire. The inner quality and outer quality of the wire rod directly affect the function of the wire.
