THE NON METALLIC INCLUSION STUDY IN CAR STEEL SAMPLES AND DETERMINATION OF ALUMINUM AND CALCIUM SOLUBLE/ INSOLUBLE PART
Journal Title: Journal of Science And Arts - Year 2011, Vol 14, Issue 1
Abstract
This paper aims to present the results of the study of Al and Ca inclusions in three car steel samples by using the Spark-Dat method. The inclusional analysis of steel's purity was realized with the 21 NEOPHOT Metallographic Microscope. Also, are presented data obtained at determination of the Ca and Al soluble/insoluble parts in the same samples. The values for the fractions (0.104; 0.067; 0.106) and (0.10; 0.10; 0.10), prove the fact that in the steel elaboration the conditions have been created for an improper behavior at continuous pouring. The values of the account totinsolAlAl/totinsolCaCa/32OAlCaO(0.00086; 0.00161; 0.00077) emphasize the fact that the steel from the samples forms the solid alumina at the temperatures of melted steel.
