Production technology and characteristics of galvanized iron wire
Wire application is very extensive, and believe that everyone has in life often see the occurrence of iron wire products, wire mainly adopted the form of low carbon steel wire rod processing, used the low carbon steel, after drawing molding, pickling, then again for high temperature annealing, then galvanized process, the process of cooling and other processing, then generate the wire.
Galvanized iron wire has good performance, toughness and elasticity is very good, the amount of zinc can reach 300 grams per square meter, and the galvanized layer is very thick, KangFuXing can also meet the requirements of use, the wire application range is very wide also, you can use in the construction industry, can also be used in hand crafts and preparation of silk screen, Can also do highway fence material, also can be used in the packing of the products, hot dip galvanized is melting in the heat of liquid zinc immersion plating, and production speed is quick, the zinc layer thickness, but not too uniform, thickness needs to be allowed on the market at present in 45 microns, high can reach more than three hundred microns, color is darker, consumption of zinc is much also, Metal forming infiltration layer and matrix, and the corrosion resistance is very good, in the outdoor environment, hot dip galvanized can stay for decades, cold galvanized or electricity galvanized, is in the plating bath by current unipolarity zinc plating on metal surface gradually, production speed is slow, but still very uniform coating, the thickness of thin, usually only 3-15 microns, appearance is very light, relatively hot dip galvanized, The production cost of electrogalvanizing is lower. Because the resulting coating is thicker, hot dip galvanizing has better protective properties than electric galvanizing, so it is an important protective coating for iron and steel products used in harsh working conditions.
