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.

The impregnated hexagonal wire mesh will lose its original characteristics after corrosion, and will change in shape, color and mechanical properties, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break and lose the original protection function. Usually there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment than dry environment easy corrosion, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the corrosion of impregnated hexagonal wire mesh, prolong the service life of products.

2. Eliminate caked zinc residue on zinc liquid surface

The difference is that hot dip galvanizing is dipped in zinc solution melted by heating, which has fast production speed and thick but uneven coating. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.

The technical term “galvanizing” means that the metal has been specially treated with zinc. Essentially, it’s wire covered with a very thin layer of zinc. It is because of this thin layer of zinc that galvanized wire has many characteristics. Zinc can be galvanized by dipping the wire into a zinc bath or by electroplating.

As we all know, even if it is the same kind of steel wire, because of the steel making process, wire drawing process and equipment are not the same, so the quality of steel wire production is not the same. Due to the different mechanical properties of steel wire itself, flattening process and equipment, the width and elongation of steel wire in the flattening process have different effects. Therefore, in the selection of wire diameter, the following three factors should be considered:
