Abstract

Abstract

Non-metallic inclusions of 72A Steel investigated invest using multi-measurements in Jiuquan Group. The amount, type, source, composition and distribution of the inclusions were discussed. The results show that more than 60% of inclusions in billet come from exotic inclusions, and 40% of inclusions in billet origin from oxides. The main reason of wire-breaking is large exotic inclusions. It is important to control the composition, shape, size and distribution of these endogenous and exotic inclusions.
