Additive for B-Si containing iron-based amorphous alloy and nanocrystalline alloy

Abstract

The invention discloses an additive for a B-Si containing iron-based amorphous alloy and a nanocrystalline alloy. The additive comprises the following components by weight percent: 70%-90% of low-carbon ferrochromium, 0-10% of Sn, 0-20% of Pb and 0-20% of Bi, wherein the low-carbon ferrochromium comprises the following elements by weight percent: 63%-75% of Cr, 0.03%-0.15% of C, 1.0%-1.5% of Si and the balance Fe and inevitable impurities. By adopting the additive for the iron-based amorphous alloy and the nanocrystalline alloy, the homogenization of molten steel can be promoted and the soft magnetic property of the alloy can be improved.

Description

technical field

[0001] The invention belongs to the field of smelting amorphous alloys and nanocrystalline alloys, and in particular relates to an additive for iron-based amorphous alloys and nanocrystalline alloys. Background technique

[0002] During the preparation of amorphous alloys, the quality of molten steel directly determines the quality of the subsequently formed amorphous alloys. Therefore, the quality of molten steel is very important for amorphous alloys, and any difference in microscopic quality will affect the quality of the final amorphous alloy. In addition, the production process of nanocrystalline alloys is almost the same as that of amorphous alloys. They must go through steps such as master alloy smelting, molten steel purification, rapid quenching into amorphous strips, and annealing. The only difference lies in the production process of nanocrystalline alloys. In the final annealing into nanocrystalline phase. Therefore, molten steel quality is also...
