Black annealed wire is a specially treated precision metal wire, the production process is as follows:
1. Material selection: Select high-quality metal materials, such as iron, copper, etc., according to different application needs, you can choose different metal materials.
2. Conductor processing: The selected metal material is processed into fine wire, usually using wire drawing or wire drawing process. In this step, the diameter and surface smoothness of the wire need to be strictly controlled.
3. Annealing treatment: The processed metal wire is heated to the appropriate temperature, usually 700-900 degrees Celsius, and kept for a period of time. The purpose of annealing treatment is to eliminate the stress inside the wire and improve its flexibility and ductility.
4. Cooling: Slowly cool the annealed wire to room temperature. This step is to stabilize the crystal structure inside the wire and further improve its performance.
5. Surface treatment: According to the application needs, the surface treatment of black annealed wire can be carried out, such as galvanized, coating, etc. This can improve the corrosion resistance and service life of the wire.
6. Inspection and packaging: Strict quality inspection of the finished black annealing wire to ensure that its diameter, surface smoothness, strength and other indicators meet the requirements.
The qualified black annealed wire is packaged into a finished product ready to be sent to the market. This is the making process of the black annealing wire.
