Problems solved by technology

Due to the unqualified appearance, size and performance, these waste strips cannot be sold or made into products such as iron cores, so they can only be discarded, resulting in a serious waste of resources and increasing production costs.
[0005] In the prior art, there is no method that can rationally utilize waste strips, save resources, and reduce production costs

Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The technical solution of this embodiment is: a method of smelting iron-based amorphous master alloy with waste strip

[0028] The method, the raw material that adopts is: waste strip material, slagging agent, pure iron, boron iron and industrial silicon; Said raw material is by weight percentage: waste strip material accounts for 0-50%, slagging agent accounts for 1-3% , the balance is pure iron, ferroboron and industrial silicon; the mass percentage of Fe, Si and B elements in ferroboron containing industrial pure iron, industrial silicon, and ferroboron except waste strips is (30-43) : (2-4): 1; The slagging agent is a mixture of quicklime and glass, and its weight ratio is 2:1.

[0029] The smelting method comprises the steps of:

[0030] Step 1, first add part of pure iron, all ferroboron and all industrial silicon into the indu...

Abstract

The invention belongs to the technical field of smelting of master alloys for amorphous materials and in particular relates to a method for smelting an iron-based amorphous master alloy with waste strips. The following raw materials are adopted: waste strips, a slag former, pure iron, ferroboron and industrial silicon. The smelting method comprises the following steps: I. firstly adding part of pure iron, all ferroboron and all industrial silicon to an induction furnace and heating the materials; II. after the materials in the induction furnace are chemically cleaned for the first time, adding all the waste strips; III. after the materials in the induction furnace are chemically cleaned for the second time, adding part of the slag former for slag forming and beating; then adding the residual pure iron; IV. when the materials in the induction furnace are chemically cleaned for the third time, introducing argon and adding the slag former for slag forming and beating; V. pouring the product into the master alloy in the required shape. The iron-based amorphous waste strips can be re-smelted by the method, and the prepared iron-based amorphous master alloy achieves the aims of saving resources and reducing the production cost.

Description

technical field [0001] The invention belongs to the technical field of smelting master alloys for amorphous materials, in particular to a method for smelting iron-based amorphous master alloys with waste strips. Background technique [0002] According to the composition of amorphous alloys, currently widely used amorphous alloys can be divided into three categories: iron-based amorphous soft magnetic alloys, cobalt-based amorphous soft magnetic alloys and iron-nickel-based amorphous soft magnetic alloys. The weight ratio of Fe in iron-based amorphous alloy is about 92%, and the rest is B, Si, C or P. It is characterized by high saturation magnetic induction (saturation magnetic induction can reach 1.4-1.7T), excellent soft magnetic properties For silicon steel sheet, the price is cheap, and it is most suitable to replace silicon steel sheet, as the iron core of medium and low frequency transformers (generally below 10 kHz), such as distribution transformers, intermediate fre...
