Abstract
The hypothesis of the dependence of the content of non-metallic inclusions in steel on the composition of the slag at the ladle-furnace has been considered. The subject of the research is an array of data on non-metallic inclusions in products, data on the chemical composition of slag on the "ladle-furnace ", the object of study is products (rails, wheels, pipes), as well as metal and slag. In the course of the study, the connection between the chemical composition of slag on the "furnace-ladle" and non-metallic inclusions in products was approximated by correlation method.
Keywords
The method of pair correlations, nonmetallic inclusions, unit "furnace-ladle".
