Abstract

Quantitative methods for determining the contamination of non-metallic inclusions (NMI) steel can be divided into metallographic, physicochemical or chemical. The quality control of steel in the metallurgical industry mostly uses a method in which their microstructure is observed on undigested destruction. In this way, the initial morphological characteristics of the NMI are revealed and their quantity, size and distribution can be estimated.Presented work is a part of a larger project investigation on the distribution of non-metallic inclusions in liquid steel, carried out using both: physical and numerical modelling research techniques. Therefore, before performing the model investigations, determinations were made, including the disclosure of the inclusions morphology occurring in the steels along with their diameters.
