The Influence of Transient Casting on Inclusions in Steel

Abstract

Influence on the transient casting of large inclusions in steel were studied by means of tracer method, kinds of steel large inclusions content in transient casting is 1.5 times ~8 times to the steady casting, large inclusions principal from crystallizer mold powder entrapment, then the tundish slag and the ladle slag. Slag and refractory has a certain influence on high quality steel. Reducing fluctuations caused by transient casting is the key to improve the quality of the steel.
