Problems solved by technology
[0003] The drawing process of nickel-chromium wire is completed through the drawing die. In order to eliminate the cold drawing hardening phenomenon and increase the elongation, it must be annealed to eliminate internal stress and defects and restore it to the physical and mechanical properties before cold working. Annealing needs to pass The annealing device performs annealing treatment, but the nickel-chromium wire of the annealing device is inconvenient to penetrate into the cooling structure, which is not conducive to annealing treatment

Description
technical field [0001] The invention relates to the technical field of alloy wire preparation, in particular to a bright annealing device and a bright annealing method for nickel-chromium wire drawing production. Background technique [0002] The main chemical composition of nickel-chromium wire is nickel and chromium, and its shape is filamentous, so it is called nickel-chromium wire. Nickel-chromium wire is also called nickel-chromium wire. Both nickel-chromium wire and iron-chromium-aluminum wire are called heating wires, because they are all electric heating resistance alloys, used as heating elements, or heating elements, also known as resistance wires, because they are often used as resistance elements. Nickel-chromium wire has high resistivity, good surface oxidation resistance, high temperature level, high strength at high temperature, good processability and weldability, and can be widely used in metallurgy, household appliances, machinery It is used as heating el...
