Problems solved by technology

For some small and medium-sized enterprises of amorphous alloy strips, most of the master alloys required for their production are produced by themselves, and there are few external sales. Due to their small production scale, the quality stability is poor
At present, the production process of amorphous alloy base metal is mostly intermediate frequency furnace smelting-casting steel ingot mold-demolding after cooling, which makes the shape of the base metal irregular and the production efficiency is low; due to the small capacity of each furnace of the smelted master alloy, resulting in There are differences in performance between furnaces, and the inclusions are unstable, resulting in unstable quality of the base metal

Embodiment Construction

[0032] The present invention will be further described below in conjunction with embodiment.

[0033] The production process of this embodiment: intermediate frequency furnace smelting——tapping steel to ladle, refining with bottom blowing argon and cooling——adding molten steel to tundish—tundish nozzle (separation ring)—mold—guiding roller table— Billet drawing machine-cutting machine-transverse cooling bed-roller table-cutting + hydraulic pressure breaking-roller table-casting billet collection.

[0034] The composition ratio of the amorphous alloy base material:

[0035]

[0036] The invention adopts the intermediate frequency furnace for smelting: the intermediate frequency furnace is used for smelting under the protection environment of argon gas.

[0037] The smelting operation process is as follows:

[0038] 1. The first furnace of the new furnace is not allowed to smelt this steel type.

[0039] 2. Material ratio: industrial pure iron 78.50%, boron iron 17.25%, me...

Abstract

The invention discloses a method for producing an amorphous alloy base material of a round billet. A high-capacity and medium-frequency furnace is utilized to smelt, and a horizontal continuous casting process is adopted to draw, so that a base material billet is regular in shape, and fewer in impurities by craft adjustment, and the produced base material is stable in quality and high in production efficiency.

Description

technical field [0001] The invention relates to a method for producing a round billet of an amorphous alloy parent material, which belongs to the field of casting. Background technique [0002] Amorphous transformers are widely used in the general trend of energy saving and emission reduction due to the advantages of low loss. Iron-based amorphous alloy strip is an indispensable basic material for the manufacture of amorphous transformers. It is used to produce the iron core of a new generation of energy-saving transformers. It is called a green, low-carbon and environmentally friendly material. One of the new materials. [0003] Amorphous alloy base material is used to prepare amorphous alloy strip. At present, in the domestic production enterprises of amorphous alloy strip, the large-scale enterprises produce the alloy base material for their own use and do not sell it to the outside world. Limited to the level of production equipment and the production conditions of the...
