A method for preparing mother ingot by melting iron-based amorphous alloy material

Abstract

The invention discloses a method for preparing mother ingots by melting iron-based amorphous alloy materials. The method comprises the following steps that raw materials containing high-proportion alloy elements are put into an airtight medium frequency induction melting furnace to be fully melted and mixed; raw materials containing low-proportion alloy elements are placed in a sealed small material adding bin to be ground and crushed into powder; argon protection gas is fed into the medium frequency induction melting furnace from the bottom of the airtight medium frequency induction melting furnace, and powder of the raw materials containing the low-proportion alloy elements are blown into a melted alloy liquid; and melting is continuously conducted for 5 min to 10 min, the materials are cooled in an argon protection atmosphere through a crystallizer, and then the magnetic material alloy mother ingots are obtained. According to the method for preparing the mother ingots by melting the iron-based amorphous alloy materials, the low-proportion alloy elements in the iron-based amorphous alloy materials can be evenly mixed with other main components, and therefore the yield and performance stability of the iron-based amorphous alloy materials are guaranteed.

Description

technical field [0001] The invention relates to the technical field of an amorphous alloy material preparation process, in particular to a method for preparing a mother ingot by melting an iron-based amorphous alloy material. Background technique [0002] The miniaturization of low-voltage power supply transformers, monitoring transformers and other electrical devices has become a development trend. To realize the miniaturization of the above-mentioned electrical devices, it is first necessary to realize high-precision transformer cores, current transformer cores and voltage transformer cores. The miniaturization of products such as cores; the miniaturization of high-precision transformer cores, current transformer cores and voltage transformer cores depends on the development of new soft magnetic materials with high saturation magnetic induction.

Problems solved by technology

[0003] Traditional transformer cores, current transformer cores and voltage transformer cores are usually made of silicon steel sheets. The advantage of silicon steel sheets is that they have high saturation magnetic induction. The disadvantage of silicon steel sheets is that they have a large loss, and low flux density
