粗钢检测

用燃烧法成功地测定了各种钢铁材料中碳元素和硫元素的含量。优异的线性度与多点校准可以精确分析从几个ppm到高达2%的碳含量。由于inductar CS cube对样品均匀性和制备要求较低，而且可以快速准确的得到测试结果，inductar CS cube元素分析仪完全适合于过程控制、质量控制或钢铁材质的认证。

分析测定钢中非金属夹杂物的是一项复杂的工作，它既需要对钢样中存在的大量夹杂物进行定量分析，测量其尺寸、形貌等，又需要测定它们的化学组成和分布，以及变化趋势等。目前，常用的夹杂物分析方法有：光镜金相法、手动扫描电镜分析法、全自动扫描电镜分析法等。

对不锈钢、镍基合金等高耐蚀性金属样品的元素组成进行了大量分析。Multiwave 5000中的20SVT50转子在高达250℃的先进温度水平下提供了成熟的SmartVent技术，从而为需要更高温度的难消化金属提供了极好的消化质量。用于内部温度测量的智能温度传感器可实现快速、准确的温度控制，这对于反应性样品尤为重要。后续分析设备用ICP-MS和AAS等可以测试结果正常。

对于传统的方法如XRF和Arc / Spark OES来说，同时测量钢铁样品中的重要元素有时是困难的，而ASI的J200 LIBS仪器为其提供了一种简单的解决方案。

钢铁材料中的碳、硫是确定钢铁产品规格和质量的重要元素，钢中含碳量增加，屈服点和抗拉强度升高，但塑性和冲击性降低，当碳量0.23%超过时，钢的焊接性能变坏。此外，碳能增加钢的冷脆性和时效敏感性。 典型的例子是低碳钢、高碳钢、高碳钢力学性能变化。 硫在通常情况下也是有害元素。使钢产生热脆性，降低钢的延展性和韧性，在锻造和轧制时造成裂纹。硫对焊接性能也不利，降低耐腐蚀性。所以通常要求硫含量小于0.055%，优质钢要求小于0.040%。在钢中加入0.08-0.20%的硫，可以改善切削加工性，通常称易切削钢。 那么针对于钢铁中的碳、硫元素我们应该通过怎样的方法来检测呢？在GB_T20123-2006规定了高频燃烧红外吸收法为标准方法，那这个方法是如何实现的呢？

钢铁中除基体元素铁以外的杂质元素有碳、锰、硅、硫、磷等。对于铁合金或合金钢来说，随其品种的不同常含有一定量的合金元素，如镍、铬、钨、钼、钒、钛、稀土等。钢铁中杂质元素的存在对钢铁的性能影响很大。 钢铁中的主要化学成分有哪些,它们对钢铁性能有何影响。

在炼油行业，管道和设备内的硫化腐蚀是导致管道泄漏的一个重要原因，硫化腐蚀可导致管道和设备寿命缩短，从而必须提前更换，以及非计划中的停运，有潜在财产损失和造成人身伤害的危险事故。若暴露于无H2的硫化腐蚀环境中，低硅含量（Si<0.10％）碳钢的腐蚀速率更将加快。

本实验采用了原子吸收光谱法测定发样中的锌和铜的含量,方法简单、快速、准确、灵敏度高。此实验用了火焰原子吸收法以及石墨炉原子吸收法对锌喝铜的含量作了检测。实验表明,锌所测得的含量为232.419:铜所测得的含量为10.0127ug/g。

1.痕量元素分析 2.湿法消解 3.基体匹配 4.标准加入 随着科技的发展，对钢铁行业提出了越来越高的要求。在不同的使用环境下，对钢铁中杂质元素的含量要求有所不同。在中低合金钢中，常见的五害元素(Pb、Sn、As、Sb、Bi)很容易在钢铁中产生偏析，富集于晶界，易于在组织中形成内裂纹，会降低钢的性能。 在采用ICP-AES对高铁基体样品进行检测时，常常因Fe的大量谱线对待测元素产生很大的光谱干扰，故选择合适的分析谱线与分析方法尤为重要。 本文采用湿法消解对中低合金钢中的Pb与Sn杂质元素进行分析。

1.常量和痕量元素分析 2.湿法消解法+微波消解 3.基体干扰 耐热钢是一种广泛应用与日常生活中的材料，由于其在高温下具有较高的强度和良好的化学稳定性也是工业上的普遍用材。铬、铝、硅在高温下能促使金属表面生成致密的氧化膜，是提高钢的抗氧化性和抗高温气体腐蚀的主要元素。但铝和硅含量过高会使室温塑性和热塑性严重恶化。所以其含量应予以控制。 同时部分样品中具有高含量的碳、硅等，属于难消解元素，故对样品前处理提出一定要求。 且在耐热钢样品中Fe、V等元素具有大量谱线常对其他元素的测量产生光谱干扰，选择合适的分析谱线以及测定方式可进行准确测量。 本文采用盐酸+高氯酸+硝酸微波消解样品，使用ICP-5000测定耐热钢样品中的铝、锡、钛、钴、铜、钼、钒、钨8种元素的含量。

不同等级的钢具有不同的元素含量指标，大多数钢和不锈钢等级规定 硫的重量百分比小于 0.05%，且磷的重量百分比小于 0.04%。利用电 感耦合等离子体发射光谱 (ICP-OES) 技术能够轻松测量样品中这一浓度范围内的元素，实验室从期望能否“完成工作”进一步考虑特定仪 器能否提高其样品通量、降低成本、简化样品前处理和仪器运行，以 及能否在大批样品分析过程中提供可靠的结果。本应用简报证明了 Agilent 5100 垂直双向观测 (VDV) ICP-OES 仪器在使用 GB/T 20125-2006 方法分析钢铁样品时的性能和优势。该仪器在这一应用中具有许多优势，包括能够快速分析大量具有挑战性的钢铁样品。

Steel manufacturers conduct quality control testing for a range of metals and trace elements to ensure the grade and performance of their final product. The Standardization Administration of China uses their GB/T 20125-2006 standard “Low-alloy steel – Determination of multi-element contents – Inductively coupled plasma atomic emission spectrometric method” to control the quality of manufactured steel products. Different grades of steel have different specifications for elemental content, with most steel and stainless steel grades required to have less than 0.05 % by weight of Sulfur and 0.04 % by weight of Phosphorus. With the Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) technique easily able to measure elements at this concentration within a sample, laboratories are looking beyond whether an instrument can ‘do the job’ to whether a specific instrument can improve their sample throughput, lower their costs, simplify sample preparation and instrument operation, and deliver reliable results throughout the analysis of a large batch of samples. 2 This application note demonstrates the performance and benefits of Agilent’s 5100 Vertical Dual View (VDV) ICP-OES instrument in the analysis of steel samples, using the GB/T 20125-2006 method. The instrument offers many advantages for this application, which involves the rapid analysis of a large number of challenging steel samples.
