The production and quality control process of copper wire rod involves the following steps:
Selection and preparation of raw material: The copper used in the production of wire rod must meet certain chemical and physical specifications. The raw material is carefully selected and prepared by removing impurities and smelting.
Smelting: Copper is melted in a melting furnace at a temperature of approximately 1,100 degrees. The smelting process is carefully controlled to ensure that the copper has the correct chemical composition.
Extrusion: Molten copper is molded into a solid block using a mold. The block is heated to a high temperature to soften it and then stretched through a series of dies to reduce its diameter and form wire rod.
Cooling: The wire rod is cooled in a cooling section to prevent warping and ensure a fine grain structure.
Annealing: The wire rod undergoes an annealing process to relieve internal stresses and improve its mechanical properties.
Inspection: Wire rod is carefully inspected for manufacturing defects such as cracks, porosity, deformation, etc.
