  • Some welding methods of galvanized steel mesh will reduce the quality of low carbon steel welded joints, such as electroslag welding. Because the line energy is high, the coarse grains in the heat affected zone of welding will become very coarse, leading to a severe reduction in impact toughness. After welding, it is necessary to normalize with refined grains to improve impact toughness.

  • Through drawing forming, pickling rust removal, high temperature annealing, hot dip galvanizing. Cooling process and other processing. Electric galvanized iron wire selection of high quality low carbon steel as raw material, after drawing, galvanizing and other processes completed. It has the characteristics of galvanized layer, strong corrosion resistance and strong galvanized layer, etc. Electric galvanized iron wire is widely used in construction, highway wall, tie-flower, net weaving and other industries.

  • The formation process of hot dip galvanized layer is between the iron matrix and the outside of the pure zinc layer, the formation of iron-zinc alloy process, the workpiece surface in hot dip plating when the formation of iron-zinc alloy layer, 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 liquid, 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 attraction between the atoms is relatively small.

  • The principle of hot dip galvanizing is simply that clean iron parts are immersed in a zinc bath through Flux wetting, so that the steel reacts with molten zinc to produce an alloyed skin film.

  • Our country industry chooses the low carbon steel with good quality as raw material, and then produces the quality galvanized iron wire by drawing, galvanizing and other processes. Now the production technology of galvanized iron wire products can be divided into hot plating and electroplating two kinds of methods. No matter which one is chosen, it should be carried out in accordance with the corresponding operating specifications, so as to better ensure the production of good products. For key and important parts with tensile strength greater than 1034mpa before plating, the stress should be released at 200±10℃ for more than 1 hour and 140±10℃ before plating.
