The wire rod should be normalized or soxhlet processed, instead of spheroidal annealing for standard large ones. Soxhlet process is widely used in the heat treatment of the center, especially the products before drawing. Avoid decarbonization during heat treatment. After heat treatment, sulfuric acid or hydrochloric acid pickling is used to remove iron sheet. The coating (see smooth carrier) can be dip-lime, phosphating, borax treatment or copper plating.

Atmospheric relative humidity At the same temperature, the percentage of atmospheric water vapor content and its vapor saturation content is called relative humidity. Below a certain relative humidity, the corrosion rate of metal antirust oil is small, while above this relative humidity, the corrosion rate increases sharply.

In the process of production, the acid activation solution can remove the corrosion products and oxide film on the surface of low carbon steel wire without excessive corrosion on the matrix. Galvanized wire can be used zincate galvanized or chloride galvanized process, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire. When galvanized wire out of the light plating should be carried out light treatment. The bath temperature of galvanized wire should be controlled well.
