  • In the production of its own, to avoid injury, wearing the corresponding work clothes is very necessary, so that not only can avoid the occurrence of accidents, but also can better realize the production and processing of products. The application of black iron wire in the process is mainly through the hot metal billet rolled into a six-and-a-half-millimeter wire, and then put it into the drawing device to draw into different diameter of the wire, gradually reduce the aperture of the drawing disk, cooling and annealing, coating and other processes to make a variety of different specifications of the wire.

  • The difference is that hot dip galvanizing is dipped in zinc solution melted by heating, which has fast production speed and thick but uneven coating. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.

  • 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.
