Popis:	Emission spectrochemical analysis of steel products is considerably affected by segregation of elements and inclusions in specimens.To cope with this inconvenience in routine check analysis of low alloy steels, “movable electrode stand”has been devised with which the electric discharge is obtained while the test piece is being moved.In using this method, proper choice of excitation conditions is necessary, for the intensity ratio of spectrum lines is different from what the usual method gives, and careful designing of the electrode assembly, the constancy of moving velocity in particular, is important for the assurance of reproducibility of analysis.
