Abstract
Description
technical field
[0001] The invention relates to a resistance material, in particular to a nickel-aluminum resistance alloy wire. Background technique
[0002] Nickel-aluminum heating resistance alloys are used in the production of overheating protection and overheating protection components for precise control of current overload, effectively preventing (motors, transformers, etc.) from overheating due to excessive current. Due to the wide range of electric heating appliances such as water dispensers, water heaters, sandwich toasters, dishwashers, dryers, disinfection cabinets, microwave ovens, electric coffee pots, electric cookers, refrigerators, air conditioners, gluing machines, office equipment, and car seat heaters use.
[0003] The working temperature of the nickel-aluminum heating resistance alloy is about 1200°C, and the alloy material is required to have high high-temperature strength, high-temperature oxidation resistance, and heat-corrosion resistance when worki...

Embodiment Construction
[0010] The proportioning ratio of the heating resistance alloy wire component mass percentage of the present invention is shown in Table 1, and the material according to the proportioning in Table 1 is smelted in a vacuum induction furnace, and argon is used for protection (also can use intermediate frequency, electroslag smelting), through hot forging---hot rolling---drawing---annealing, the nickel-aluminum heating resistance alloy wire of the present invention is obtained. The specific preparation method of the heating resistance material wire is as follows:
[0011] 1) Vacuum induction smelting or intermediate frequency + electroslag remelting is used to smelt the above-mentioned alloys. The addition of various elements can be added in pure metals or in the form of intermediate alloys.
[0012] 2) Drawing the above alloy through hot forging, hot rolling, and heat treatment, and then repeating heat treatment and drawing to the wire material of the required specification.
