Resistance material for prolonging service life of overheated element

Abstract

The invention discloses a resistance material for prolonging the service life of an overheated element. The resistance material mainly comprises Ni, Si, Mn and Ti. Under the condition that the resistivity of a prepared resistance alloy is ensured, the high-temperature service life of the resistance material is prolonged remarkably.

Description

technical field

[0001] The invention relates to a resistance material, in particular to a resistance material for prolonging the service life of an overheating element. 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, ...

Examples

Embodiment Construction

[0010] The proportioning ratio of the component mass percentage of the resistive material prolonging the service life of the overheating element according to 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 be used intermediate frequency, electroslag smelting), and through hot forging---hot rolling---drawing---annealing, the nickel-aluminum heating resistance alloy of the present invention is obtained. The specific preparation method of the heating resistance material 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 draw...
