  • 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.

  • The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion to the matrix. Galvanized wire can be zincate galvanized or chloride galvanized process, should use appropriate additives to obtain the low carbon steel wire standard requirements of the coating. When galvanized wire after light plating should be light treatment. Control the temperature of the bath of galvanized wire.
