Annealed black iron wire is made from low-carbon steel wire rod as raw material.
The production process usually includes the following main steps:
1. Raw material preparation: Select high-quality low-carbon steel wire rods and inspect and pre treat them.
2. Wire drawing: Use a wire drawing machine to pull the wire rod into the required diameter of iron wire.
3. Annealing treatment: Annealing is carried out in a specific annealing furnace to reduce the hardness of the iron wire and improve its toughness and ductility.
4. Surface treatment: Remove the oxide layer and impurities on the surface to ensure the smoothness of the wire surface.
5. Inspection and packaging: Conduct quality inspection on the finished products and package them after passing the inspection.
