双联法冶炼铁基非晶合金母材的工业化技术开发

Commercial Technical Development of Duplex Process for Smelting Iron Base Amorphous Alloys Parent Metal

通过实验室试验及磁性能测试,确定了合金的成分(Fe80Si7B13);通过合理的工艺路线和中频炉设备适应性改造,重点是增设熔炼及浇铸过程的氩气保护设施及使用低碳低熔点保护渣,采用转炉和中频炉双联工艺生产出了夹杂物<5μm的非晶合金母材。与传统冶炼工艺相比,生产成本每吨低约3 500元,实现了铁基非晶合金母材的低成本和规模化生产。

The compositions of the Fe80Si7B13 alloys were determined by laboratory test and magnetic energy testing. Through the reasonable process route and adaptive transformation of the medium frequency furnace equipment, the emphasis is on the addition of argon protection facilities in melting and casting process and the use of low carbon and low melting point protection slag, the amorphous alloy with〈 5 μm inclusion was produced by duplex steelmaking of converter and intermediate frequency furnace. Compared with the traditional smelting process, the production cost of the product is reduced about 3 500 Yuan per ton and the low- cost and scale production of iron base amorphous alloys parent metal is realized.
