ANALYSIS ON CHEMICAL COMPOSITIONS OF HIGH SPEED WIRE ROD

The present paper discussed the experimental technology for analysis on the chemical compositions of the high speed wire rod using the direct reading spectrograph. Results indicate that secondary processing on the quenched samples can improve the analytical precision of the carbon content; and increase in Ar gas flow rate and use of the high hardness alloyed steel as the specimen platform is benefitial to the improvement in the analytical precision of N content; and application of the new type high power excitation source to the analysis on Ca content and utilization of the type calibration method in the analysis on Al content have achieved satisfactory results; and implementation of the longitudinal flattening method can effectively solve the problems about analysis on the chemical compositions of the small diameter finished wire rod using the direct reading spectrograph.
