Problems solved by technology

The problem with the amorphous alloy strip is that the strip-making process conditions are high, the strip surface made of strip has many sand holes, and the quality of the strip is difficult to be guaranteed.
The main problem of the amorphous alloy material is that the carbon content is high, the smelting process requires high requirements, the process is complicated, and the carbon content in smelting is unstable.

Embodiment 1

[0032] 1) Prepare raw materials such as pure iron, pure silicon, ferroboron, chromium, copper and cast iron powder. The weight ratio of chemical components in the raw materials is as follows: iron 92kg, silicon 6kg, boron 3kg, chromium 0.2kg, copper 0.02kg, carbon 0.1 kg.

[0033] Among them, boron comes from ferroboron with a boron content of 17%, and carbon comes from cast iron powder with a carbon content of 30%, so the iron is the sum of the weight of industrial pure iron, ferroboron and iron in cast iron powder.

[0034] 2) Loading, vacuuming, heating

[0035]Put all the pure iron into the vacuum smelting furnace (produced by Xiangtan Electric Furnace Factory; power 100KW), and then sequentially load chromium, silicon, ferroboron, copper and cast iron powder raw materials, cover the vacuum smelting furnace tightly, and start the machine The pump evacuates the vacuum furnace. When the relative vacuum of the vacuum smelting furnace reaches 200Pa (that is, the vacuum pressu...

[0048] Prepare raw material pure iron, pure silicon, boron iron, chromium, copper and cast iron powder, make in the raw material have the chemical composition of following weight ratio: iron 93kg, silicon 6.05kg, boron 2.5kg, chromium 0.15kg, copper 0.02kg, Carbon 0.09kg.

[0049] Other than that, it is the same as in Example 1. The product technical performance index detection of the obtained iron-based amorphous alloy strip is shown in Table 1.

Embodiment 3

[0051] Prepare raw material pure iron, pure silicon, ferroboron, chromium, copper and cast iron powder, make in the raw material have the chemical composition of following weight ratio: iron 91.0kg, silicon 6.15kg, boron 2.90kg, chromium 0.18kg, copper 0.018kg , carbon 0.12kg.

[0052] Other than that, it is the same as in Example 1. The product technical performance index detection of the obtained iron-based amorphous alloy strip is shown in Table 1.

Abstract

The invention provides an amorphous alloy material with Fe as the main component and a preparation method thereof. The amorphous alloy material of the invention comprises the chemical components with the following parts by weight: Fe: 91.0-93.5; Si: 5.2-6.6; B: 2.5-3.3; Cr: 0.05-0.25; Cu: 0.010-0.030; and C: 0.05-0.20. The Fe-based amorphous alloy belt material has simple design in components, and good mechanical property and fine processability of the material; moreover, yield is over 90%. In addition, the manufactured Fe-based amorphous alloy belt material has high comprehensive magnetic property; and coreloss of a transformer manufactured by the amorphous alloy material is greatly reduced. The Fe-based amorphous alloy belt material enjoys wide application and low use cost and serves to save energy and protect the environment.

Description

technical field [0001] The invention relates to an amorphous alloy soft magnetic material, in particular to an amorphous alloy soft magnetic material with iron as the main component. Background technique [0002] Amorphous material is a new type of "superconducting magnetic" material born in the 1970s. Amorphous material and its preparation process are internationally recognized as a revolutionary progress in metal materials and metallurgical processes. Known as green material. The main raw materials of these amorphous materials are iron, silicon, boron, etc. Usually, the quenching technology of quenching and solidifying the master alloy from the molten state is used to prepare amorphous alloy thin strips, which are cast into thin strips by rapidly solidifying them. The thickness of the ribbon is less than a quarter of that of a human hair, and finally an amorphous alloy ribbon with short-range order and long-range disorder in the arrangement of atoms is obtained.
