Pet cage is generally made of high quality iron wire, low carbon steel wire, stainless steel wire welding, which is characterized by beautiful, lightweight, folding, easy to store. The surface treatment of pet cage is generally: cold galvanized, hot galvanized, spray, dip, chromium plating, nickel plating and other methods.

The application of electric welding net is more widely, at present it has replaced the use of other parts of the wire mesh, the cost of electric welding net is lower, the production speed is very fast, so it is very popular. Welding net galvanized before the need for processing is recrystallization annealing, because the welding net must maintain a no oxide and no other impurities of pure iron active surface, if you can not keep its surface clean will lead to a bad galvanizing effect, galvanized layer and iron material is not closely combined, so this step is necessary.

Large roll galvanized wire is processed by low carbon steel wire rod, through drawing molding, pickling rust removal, high temperature annealing, cooling and other processes. Large roll galvanized wire electroplating temperature should be controlled in 30-50℃. Because of the strong corrosivity of chloride ions in bath, quartz glass heater is generally used. Continuous production does not need heating, but need cooling cooling.

There are three methods to detect the thickness of zinc layer of galvanized wire: weighing method, cross section microscopy method and magnetic method, among which the first two experiments will cause certain damage to galvanized wire, including the length of galvanized wire and the reduction of dosage. The general detection of galvanized wire galvanized layer is detected by magnetic method, which is also a more intuitive and convenient method. The standard of galvanized layer thickness is related to the wire diameter of galvanized wire. The larger the wire diameter of galvanized wire, the thicker the galvanized layer is. It is the thickness of galvanized layer and cast iron after centrifugal separation.

There are still some differences between electric mesh and wire mesh and steel mesh. This mesh is mainly a welding mesh made of high quality low carbon steel wire after straightening and cutting, and then welded by electric welding equipment. It can be said that because of the characteristics of fast production and convenient transportation, it has been applied in many industries. In today’s construction projects, people can also see the image of this network well. The application of welded mesh in this industry is mentioned because of its strong corrosion resistance and uniform mesh. It has become a special grid for floor heating in construction industry and has been applied in many fields.

With the development of mining industry, pig iron classification in Our country has been very extensive, to meet the needs of the machinery industry. Generally speaking, iron wire factory produces galvanized iron wire iron can be divided into two categories, is directly from the iron ore through iron tracing exercise out of the metal, the primary components of the ore is iron oxide, silica and other miscellaneous stones. When this ore is specially refined into metal iron, the elements such as carbon, silicon, manganese and so on are mixed in, so that the refined data is called – like general pig iron, also for the initial grade of the material.
