摘要： Provided are a method for analyzing nitrogen in a metal sample with which nitrogen content in a metal sample is determined accurately and at low cost, an apparatus for analyzing nitrogen in a metal sample, a method for adjusting nitrogen concentration in molten steel, and a method for manufacturing steel. The method for analyzing nitrogen in a metal sample according to the present invention includes: a melting process in which a metal sample containing a nitrogen component is melted in an argon gas atmosphere by performing impulse heating to gasify the nitrogen component; and an analyzing process in which nitrogen content in the metal sample is determined by analyzing nitrogen gas generated in the melting process and the argon gas by using a gas discharge optical emission method. By analyzing the nitrogen concentration of a sample taken from molten steel by using the analysis method described above, and by determining treatment conditions for adjusting nitrogen concentration on the basis of the nitrogen analysis value derived by the analysis, nitrogen concentration in molten steel is adjusted.

摘要： A calibration assembly generates elemental mercury and oxidized mercury for calibrating components of a mercury monitoring system, including making necessary adjustments to efficiencies of a mercury compound converter and an elemental mercury detector. The calibrator generates an elemental mercury sample having a known elemental mercury concentration, [Hg 0 ] 1 and combines an oxidizing component with the elemental mercury sample, thereby producing a reduced concentration of elemental mercury [Hg 0 ] 2 within the sample. The calibrator measures the concentration of elemental mercury [Hg 0 ] 2 within the sample and calculates a difference between the known elemental mercury concentration, [Hg 0 ] 1 and the reduced concentration [Hg 0 ] 2 . The difference between [Hg 0 ] 1 and [Hg 0 ] 2 is substantially equal to the concentration of oxidized mercury produced by the calibrator. The concentration of oxidized mercury can also be calculated as the difference between elemental mercury detected after passing a sample stream containing oxidized mercury through a channel which includes the converter and the reduced concentration [Hg 0 ] 2 detected after passing the sample stream through a channel which bypasses the converter. By providing oxidized mercury at calculated concentrations, the calibrator allows a user to calibrate continuous emission monitoring systems for accurate response to both elemental mercury and oxidized mercury.

摘要： Electromagnetic acoustic resonance (EMAR) method by using an electromagnetic acoustic transducer (EMAT) is used for determining hydrogen concentration of a radioactive metallic object. In one preferred embodiment, resonance frequencies fr, fr are measured with the EMAT, where fr is a resonance frequency when a direction of an amplitude of a transverse ultrasonic wave generated by the EMAT is the same as the rolling direction of the metallic object of rolled material, and ft is a resonance frequency when a direction of the amplitude of the transverse ultrasonic wave is perpendicular to the rolling direction. A value R is calculated by using: R = (fr - ft)/{(fr + ft)/2}. The hydrogen concentration of the metallic object is calculated on the basis of the experimentally determined relation between the value R and hydrogen concentration.
