  • The external environment has great influence on the preservation of galvanized wire mesh. In the rainy season, it is necessary to pay attention to the air humidity of the workshop, warehouse and other departments. It is recommended to use a humidifier. Usually, the moisture absorption of book paper is larger than that of powder paper, and the pH value is higher. Generally speaking, in the normal environment of storage wire, storage time of two years is not corroded wire phenomenon. However, it should be noted that in the process of handling the iron wire, it should be handled gently to avoid the position of the coiling coil, which will cause the smooth pulling of the wire and affect the production.

  • During this process, each time the wire is pulled over, the surface hardens due to the high friction temperature. So basically every time you pull it you have to annealing it in the furnace. On the one hand, it is to reduce the surface hardness. On the other hand, during the process of wire pulling, only the surface is deformed, and the center is unchanged. So there’s a lot of stress inside. Therefore, it is necessary to rely on annealing to eliminate the internal stress, so that the wire becomes soft again to eliminate the stress before being drawn again.
