Abstract In metallurgical steel making a quick analysis of on-the-spot sample is required to know the process of steel making. A new-type spectrometer,laser-induced breakdown spectrometer developed by ourselves,was presented in the present paper. A Nd∶YAG laser with pulse width of nanometer was used as an ionization and excitation source. Emission from the plasma appeared when the laser beam was focused on the surface of sample. After it was spectrally resolved by a Paschen-Runge polychromator,detected by photomultiplier detectors,integrated by gate intensifier,and converted by analog-to-digital converter,the final result was transmitted to a computer in order to complete data processing. Compared to the common spectrometer on-the-spot in metallurgy,this instrument allows fast analyis without sample preparation (one minute or less),with high precision and sensitivity,so it is very suitable for the analysis of on-the spot sample in metallurgy. In recent years with the fast development of optical fiber,on-line analysis of liquid steel and dynamical control of metallurgical processing will come true by using this instrument.
