A Spectral Analysis of Tool Steel by a Low-voltage Spark Source and a Line Array Ultraviolet CCD Sensor

In this work, we propose a novel analysis lines and comparative lines of the six alloy elements of the tool steel (W, Cr, V, Si, Mn, Mo) within the bandwidth of 280nm~310nm wavelength for carrying out the simultaneous quantitative analysis for the six alloy elements of the tool steel. Steels have fundamentally different in their qualities depending on the types and amounts of elements added. In reality, special steels are produced for the several purposes. The correct and rapid analysis of the amounts of elements required and impurities involved for the steel produced is important for the quality of the product. The most frequently used additives in the metal industry are the six elements mentioned above. However, the method of simultaneous and rapid analysis of the above-mentioned elements is not completed. Here the key point is to choose an analysis line and a comparative line for each element used in the analysis. Especially, tool steel plays an important role in the machining industry. The ultraviolet sensors have been extensively used for the spectrum analysis in the steel industry in recent years. We propose a method that quickly analyses tool steel material by combining the ultraviolet sensor with a computer. We choose an analysis line and a comparative line for Si, Mn and Al, which are auxiliary impurities, and for W, Cr and V, which are main alloy components, and make a test curve. According to our recent work, this is the first paper that deals with the analysis of the tool steel by combination of ultraviolet sensor and computer.
