Losses of Metal During Continuous Casting of Stainless Steel Slabs Alloyed With Titanium and the Ways of Their Reduction

Abstract

The paper deals with the factors affecting the formation of rough surface defects during continiuos casting of stainless steel alloyed with titanium and, as a consequence, losses of metal during casting. The general view and chemical analysis of non-metallic inclusions in rough surface defects of continuously cast slabs are provided. It is affirmed that conditions of casting, rather than melting and preparation to casting, have a critical effect upon surface defect formation. The changes of chemical composition of slags in the mold (at the starting, middle and finishing moment of casting the heat) and in the tundish (at the same moments near the ladle shroud and near the stopper) are also determined
