New process for producing amorphous state strip under non-vacuum

Abstract

The invention relates to a new process for producing an amorphous state strip under non-vacuum. The new process is characterized by being performed according to the following steps that firstly, high-purity pure iron molten steel is produced, the high-purity pure iron molten steel is prepared by adopting ZL201410341008. 4, with the name of high-purity pure iron molten steel produced by a method for producing high-purity pure iron; secondly, Si, B and P alloys are matched into the high-purity pure iron molten steel to form amorphous magnetic material molten steel which flows onto a cooling copper roller rotating at a high speed through a nozzle wrapping seam of a spray nozzle of a crucible, and the molten steel is cooled into a thin strip suddenly and violently. According to the new process, an ultra-short flow path system composed of a coal-based vertical furnace and an intermediate frequency smelting system is utilized for producing low-impurity pure iron with iron larger than 99.9% to serve as a high-quality base material of an amorphous nanocrystalline soft magnetic material, and effective self control and improvement of the product quality are achieved. The new process is shorter than a traditional amorphous state strip technological process, little in tool equipment, saving in investment, low in energy consumption, low in cost and capable of performing self control on theproduct quality.

Description

technical field [0001] The invention relates to a new process for producing amorphous strips under non-vacuum conditions. Background technique [0002] In recent years, with the development needs of my country's industry 2025, the continuous improvement of production equipment in various industries and the development of high-tech industries in the fields of communications, audio-visual, electrical engineering, automation equipment, automobiles, magnetic separation and bioengineering, magnetic materials, amorphous The rapid development of pure iron alloys has brought a broad market to the pure iron industry [0003] The domestic and foreign raw material pure iron is developing towards ultra-purification, which promotes the development of hard magnetic materials (such as NdFeB) and soft magnetic amorphous materials (such as SiFeB). [0004] Amorphous alloy, also known as metallic glass, is a long-range disordered metal solid, which usually refers to the mixing and melting of ...
