自动化硼酸盐熔融与X-射线荧光光谱分析组合技术在铁合金工业中的应用

Integration of the robotized borate fusion technique with XRF analysis within the context of the ferroalloy industry

铁合金是高附加值的金属,在用作钢铁行业的原材料时,铁合金可以调节钢的最终成分并赋予其物理和化学性质。在炼钢过程中,精确控制铁合金加入量可以降低成本,另外,铁合金中的杂质又可能影响钢的性能。铁合金正确的表征是必要的,因为这对钢的生产质量以及钢铁生产企业的经济效益有重大影响。在种类繁多的铁合金中,采用硼酸盐熔融制备样品并用X-射线荧光光谱测定主次及一些微量元素是非常有效、广为人知的方法,有着很好的准确度和精度。多种高性能的熔融仪器可被集成rFUSION自动熔融系统,该系统的熔融片制备可实现独立操作而不用人工介入。对于生产来说,rFUSION自动熔融系统可以提高并且稳定分析速度,确保分析结果的质量不会因生产率而降低。另外,因为采用有效的标准化设计、rFUSION熔融系统还可以确保熔融过程的标准化,使结果有很好的一致性和均匀性。

Ferroalloys are high added-value materials used as raw materials in the steel industry for adjusting the final composition of steel and providing its physical and Chemical properties. A precise management of the quantities of ferroalloys added in the steel making process leads to significant sav- ings. Moreover, impurities in ferroalloys can affect the properties of steel. Proper characterization of ferroalloys is necessary since it has significant impacts on the quality of steel production, along with major financial consequences for steel manufacturing companies. Sample preparation by borate fusion, coupled with XRF analysis, is an effective and renowned technique for accurate and precise determination of major, minor and some trace elements in a wide range of ferroalloys. High performance fusion instruments can be integrated into the rFUSION robotized system, allowing fused disks preparation to run independently and without manual intervention. In regard to production, the rFUSION automated fusion system increases and stabilizes analysis output rates while assuring the quality of results is never compromised over productivity. In addition, the rFUSION ensures of the fusion process and brings consistency and uniformity of the results, owing to its standardization design.
