Inclusion quick analysis technique for clean steel

TANG Fuping,CHANG Guihua,LI Hong,CHEN Benwen,LI Guangbang Ansteel Co.Ltd.,Anshan 114001,China  
The principle of analyzing inclusions in steel by spectrum instrument was presented.The curve of Al2O3 pulse intensity by spectrum with its content by chemical analysis was established based on studying original Al2O3 pulse intensity from spectrum instrument,the relationship between the spectrum intensity and the inclusion size was determined,at last Al2O3 content and size distribution analysis on-line was realized.In comparison of chemical methods,the average error of the spectrum method is 3×10-6.The time of analyzing the inclusion content and size was shortened to 5 min from 2-5 d,which can offer a effective inclusion analysis technique for inclusion on-line control in steel-making and refinement processes.
