Life said “wire”, in fact, is “low carbon steel wire”, carbon content in 0.2% below. The surface is usually coated with zinc coating because it is easy to rust. Under atmospheric conditions, the galvanized layer will not rust before most of the fall off, relatively soft. Life said “steel wire”, is the carbon content of about 0.6% of the “carbon steel wire”, or carbon content of about 0.8% of the “high carbon steel wire”, they have enough hardness and elasticity after appropriate heat treatment, high strength. The use of words such as winding ordinary spring and so on.
Hot dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot dip galvanizing is to first pickling the iron and steel parts. In order to remove the iron oxide on the surface of the iron and steel parts, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
Its wire diameter specifications include: 8#-24#, with thick coating, corrosion resistance, strong coating and so on. And according to the special needs of users, according to industry standards to provide various specifications of galvanized wire. Low carbon steel wire is called galvanized iron wire after drawing and galvanized, so galvanized wire products have certain characteristics. In order to better let galvanized wire play an effect, in the process of galvanized wire, generally according to customer needs to control the thickness of galvanized wire zinc layer, so that galvanized wire can meet the needs of customers.
There are two kinds of use, namely slope protection hook mesh, coal hook mesh, mining hook mesh, coal mine support network, roadway support network. The height of the outer rail of the pavement or seat belt should not be less than 1.10 m. The net distance between balustrade members shall not be greater than 140 mm, and horizontal rail shall not be used. Hook mesh planning is necessary to be safe and reliable, anchor should be installed on the basis of the railings, its strength should meet the requirements of the standard.
Compared with galvanizing, hot-dip galvanizing has lower production cost and less environmental impact than galvanizing. Because the coating obtained is thicker, hot-dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for steel parts used in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, ocean exploration, metal structure, electric power transmission, shipbuilding and other industries.
Environmental factors should be considered when choosing the thickness of galvanized layer. Galvanized wire in galvanized, pay attention to the above problems, can be well galvanized, to ensure the quality of galvanized wire. Galvanized methods are mainly divided into two types, one is hot dip galvanizing method, the other is electric galvanizing method. This paper mainly introduces the method of galvanizing. Electrogalvanizing is an electrolyte used for galvanizing.
