Application of M-EMS on Billet Caster for Producing Medium and Low Carbon Steel

Tang Jian-ping

Abstract

The paper introduces application of M-EMS on billet caster for producing medium and low carbon steel in Steel-melting Plant of Baotou Steel in detail.Practice confirms that M-EMS can refine grain size of steel,which can make the average grain size of 08Al steel increase from 9.0 to 9.6,and the average grain size of SWRCH·35K steel increase from 9.9 to 10.6.At the same time,M-EMS can improve internal quality of continuous casting billet with medium and low carbon steel remarkably,enlarge central equiax crystal zone of casting blank,and decrease centre burst and segregation,which are particularly obuious for medium carbon steel.
