Research of Influencing of an Elemental Composition of Steel and Ways her having Poured on Quality of Hire with Usage of Methods of Mathematical Statistics

摘要

The statistical analysis of steel chemical composition, influence on rolled metal guality has been made; the ways of steel pouring have been investigated. As the object of research of a tube billet and an axial billet at the Dneprovsky iron and steel works have been taken. The regressive equations describing the guality of the billet, that can be used ready rolled product control are obtained.
