Iron wire is a metal wire made of iron, wire according to different purposes, composition is not the same, it contains elements: iron, cobalt, nickel, copper, carbon, zinc, and other elements. The wire is divided into several types according to its thickness. Iron wire production developed earlier because of its simple technology and wide application. Iron wire or steel wire is steel wire again cold-working products, the materials used are generally selected superior carbon steel or stainless steel. Usually, to produce iron wire (steel wire) ingots (ingots) , we need to go through several procedures such as peeling, pickling, washing, water washing, saponification, drying, drawing, annealing, cooling, pickling, water washing, galvanizing line, packing and so on. Wire and steel wire are generally produced by wire drawing and galvanizing. For example, widely used in industry, agriculture, aquaculture, construction, transportation, mining and other fields of welded wire mesh is made of high-quality low-carbon iron wire, then after cold plating (electroplating) , hot plating, PVC packaging and other surface passivation, plasticizing treatment, the production of Metal Mesh Level, Mesh uniformity, solid solder joints, with stability, corrosion, corrosion resistance good characteristics. The stainless steel welded wire mesh is made of high-quality stainless steel wire, such as machine shield, livestock fence, flower and wood fence, window guard fence, aisle fence, poultry cage and Home Office food basket, paper basket and decorative articles, etc. , more acid-resistant, alkali-resistant, welding firm, beautiful and so on. Galvanized wire in high-quality low-carbon steel wire processing, is the use of high-quality low-carbon steel, after drawing forming, pickling derusting, high-temperature annealing, hot galvanizing. Cooling and other processes from processing. Galvanized wire is divided into hot galvanized wire and cold galvanized wire (galvanized wire) . There is also a certain skill to distinguish between cold galvanized wire and hot galvanized wire. Hot Galvanized wire is dipped in a heated molten zinc bath. The production speed is fast, the coating is thick but uneven, and the thickness of the coating is 45 microns, which is permitted in the market, up to 300 microns or more. Dark color, consumption of zinc metal, and the matrix metal caused by infiltration layer, corrosion resistance, outdoor hot-dip galvanizing can be maintained for decades. Cold galvanizing wire (galvanizing wire) is in the galvanizing bath through the current unidirectional so that zinc gradually coated metal surface, slow production speed, average coating, thin thickness, usually as long as 3-15 microns, bright appearance, poor corrosion resistance, a few months will rust.
