Description

Technical Field

[0002] Cables usually need to be annealed after drawing. Annealing is a heat treatment process that improves the structure and performance of the material by heating the metal material to an appropriate temperature and keeping it warm for a period of time before cooling it to room temperature. During the cable drawing process, the metal material will be stretched and deformed, causing the internal grains of the material to deform or precipitate, reducing the plasticity and strength of the material. In order to restore the plasticity of the metal material, reduce residual stress, and improve mechanical properties and processing performance, the cable needs to be annealed. By reasonably controlling the annealing process parameters such as temperature and holding time, the metal grains can be rearranged and internal stress can be eliminated, thereby softening the metal and improving processing performance. The annealed cable has better machinability and ductility, and is suitable for subsequent molding and processing processes.

[0003] In the existing cable drawing, when the cable is annealed after being drawn, a boiler system is usually used to perform secondary heating on the cable. However, the secondary heating of the cable using a boiler system is prone to uneven heating. Utility Model Content
