Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the examples.

[0026] The preparation process of the Fe-Ni-Mo alloy for the buzzer of the present invention includes: vacuum induction furnace smelting, forging billet opening, hot rolling into a strip billet, cold rolling into a finished product, and then tension straightening and low temperature stress relief annealing.

[0027] Specifically include the following steps:

[0028] (1) adopt the composition ratio shown in Table 1 to add raw materials, adopt vacuum induction furnace to smelt, obtain Conical alloy ingots;

[0029] (2) Forging: under the condition of 1100-1180 ℃, heat preservation for 1-1.5 hours, forging into a forging billet of thickness (50-90mm)×width (180-300mm).

[0030] (3) Hot rolling: under the condition of 1100-1170°C, keep warm for 30-60 minutes, and hot-roll into a hot-rolled billet of thickness (5-8mm)×width (180-300mm).

[0031] (4) Cold rolling: multi-p...

Abstract

The invention discloses a Fe-Ni-Mo alloy for a buzzer and a preparation method thereof. In terms of weight percentage, the alloy comprises the following components: Ni 47-48.5 wt%, Mo 0.20-2.0 wt%, Si 0.10-0.20 wt%, B 0.01~0.30wt%, Nb 0.05~0.15wt%, Y 0.05~0.10%, C≤0.03wt%, S≤0.02wt%, P≤0.02wt%, the balance is Fe and unavoidable impurities . It is prepared by smelting in a vacuum induction furnace, forging billets, hot rolling into strip billets, cold rolling into finished products, and then undergoing tension leveling and low temperature stress relief annealing. The alloy material in the invention can be used for the buzzer, and has excellent mechanical properties, magnetic properties and corrosion resistance.

Description

technical field [0001] The invention relates to an alloy material and a preparation method thereof, in particular to an Fe-Ni-Mo alloy and a preparation method thereof. Background technique [0002] With the modernization of science and technology and the rapid development of automation, the development of the electrical appliance industry and the electronic information industry is becoming more and more modernized and automated. The automatic control technology of electrical appliances in the electrical appliance industry has brought great convenience to information transmission and safe production. The application of automatic alarm devices is becoming more and more extensive, so the production and application of buzzers are also increasing year by year. [0003] The material of the vibrating and sounding thin film in the buzzer needs to have certain magnetic properties, high hardness and other characteristics. At present, with the continuous improvement of the applicatio...
