Hot dip wire is made of high quality low carbon steel, high carbon steel, by drawing, hot dip galvanized processing galvanized wire. Hot dip galvanized wire production process: wire rod – large drawing – annealing – medium drawing – annealing – galvanized. Hot dip galvanized wire has the characteristics of thick coating, strong corrosion resistance and firm coating. And according to the special needs of users, according to industry standards to provide various specifications of galvanized wire. Hot-dip galvanized wire is of better quality than electric galvanized wire. In the production process of hot dip galvanized wire more than an annealing process, so hot dip galvanized wire corrosion is stronger than electric galvanized.
Hot wire average performance: reflected in its cross section, longitudinal uniformity. In the actual operation process, such as the jitter of steel wire, the surface scum in the plating pan and other reasons will cause the accumulation of galvanized layer on the surface of galvanized wire, should try to solve the problem. In addition to these reasons, it is necessary to pay attention to the tooling and process must be stable, and to do regular tests to ensure the uniformity of galvanized layer.
The corrosion resistance of hot-dip galvanizing is much higher than that of cold galvanizing, also known as electric galvanizing. Hot wire will not rust for years, cold galvanizing will rust in three months. Cold galvanizing process is used to protect the metal from corrosion. For this purpose, the coating of zinc filler is used, which is coated on the protected surface by any coating method. After drying, the zinc filler coating is formed, and the content of zinc in the dry coating reaches 95%.
Steel is galvanized on the surface under the condition of cooling, and hot dip galvanized steel pipe is galvanized on the surface under the condition of hot dip, its adhesion is very strong, not easy to fall off, although hot dip galvanized pipe rust phenomenon, but in a very long period can meet the technical and health requirements.
