钢中痕量硼作为辅助合金元素,可以增加钢的淬透性,硬度和抗张力,改善钢的焊接性能。因其含量低(0.000X％～0.00XX％),超出了炉前化学分析的分析范围。我室以美国DV-4光谱仪,使用优选标样和正确的元素干扰校正方法,分析钢中痕量硼,获得了较好的准确性和分析精度,缩短了分析时间,达到了炼钢生产炉前快速分析的要求。 1 试验部分 1.1 仪器与工作条件 光谱仪:Spectrovac 1000(DV-4)真空直读光电光谱仪(美国Baird公司)40通道 计算机系统:IBM-PC/XT,使用MC-20软件(美国Baird公司)
Trace boron in steel as an auxiliary alloying elements can increase the hardenability of steel, hardness and tensile strength and improve the welding performance of steel. Because of its low content (0.000X% ~ 0.00XX%), beyond the chemical analysis of the furnace front of the analysis. My room to the United States DV-4 spectrometer, the use of the preferred standard sample and the correct element interference correction method, the analysis of trace boron in steel, obtained good accuracy and accuracy, shorten the analysis time, reached the steelmaking furnace Quick analysis before the request. 1 Experimental 1.1 Instrument and working conditions Spectrometer: Spectrovac 1000 (DV-4) vacuum direct reading photoelectric spectrometer (Baird, USA) 40-channel computer system: IBM-PC / XT using MC- 20 software (Baird, USA)
