  • The precautions of galvanizing wire in galvanizing are introduced in detail! When galvanized wire is galvanized, it is generally necessary to pay attention to the following problems: the duration of the protective effect of galvanized wire is greatly related to the thickness of the coating. Generally speaking, in the dry main gas and in indoor use, the thickness of galvanized wire galvanized layer only 6-12 μm “, and in harsh environmental conditions, galvanized wire galvanized layer thickness needs 20μm “to B height up to 50μm”. Therefore, the environmental impact 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.

  • Deoxygenation of boiling steel is incomplete, oxygen content is high, phosphorus and other impurities distribution is uneven, local overspending, aging sensitivity and cold brittle sensitivity are high, hot cracking tendency is added. If unqualified electrode is used, if the content of carbon and sulfur in the weld metal is too high, cracks will occur. For example, when factories use acidic electrodes to weld Q235-A steel, the high carbon fernoganese in the electrode coating will lead to thermal cracks in the weld.

  • Cold wire drawing is a kind of cold processing of metal. The raw material is wire rod, which is produced by peeling, galvanizing and other processes. Galvanized cold drawing is used more in building materials. Its testing standards are also different. The strength of cold drawing is relatively high. Because of the high strength of steel, it plays a very important role in construction. It saves the construction steel in building materials, and also reduces the cost of the project. It also plays a very important role in the structure of concrete.

  • Galvanized wire coating is galvanized, aluminum plated, coated with nylon or plastic, etc. Zinc is divided into thin coating of steel wire after plating and thick coating of galvanized steel wire after drawing. The mechanical properties of thick coating are reduced compared with smooth steel wire rope, which should be used in severe corrosion environment. It is more resistant to corrosion, wear and heat than galvanized wire rope, using the first plating and then drawing method of production. Coated nylon or plastic wire rope is divided into two kinds of coated rope and coated stock after the rope.
