硅—铝—钡—铁合金在高碳钢生产中的应用

USE OF SiAlBaFe DEOXIDANTFOR STEELMAKING PRODUCTIONOF HIGH CARBON STEEL

进行了硅—铝—钡—铁合金替代硅—铝—铁合金应用于高碳钢的终脱氧工业性试验，结果表明，由于硅—铝—钡—铁脱氧剂中钡在钢水中的作用，使钢的奥氏体晶粒度、非金属夹杂物、硫化物的级别均优于硅—铝—铁合金脱氧的钢，因而完全可以取代后者用于炼钢中脱氧，而且还可减少吨钢用铝量。

Industry experiment of application SiAlBaFe deoxidant for steelmaking production of highCarbon steel was did. Results show, because of the action of the Barium in the complex deoxidant, purity quality of steel was made progress, austenic crystal grai was made fineness, mechanical property of steel was improved.
