Abstract：
The continuous casting techniques of several typical special steels(bearing steel and spring steel)slab were reviewed.The applications of low and superheat casting,electromagnetic stirring and light pressing were illustrated.The improvement of internal quality of slabs,the causes of micro segregation,macro segregation and carbide unevenness of slabs and the improvement measures indicate the important significance of electromagnetic stirring and light pressing technology in improving the internal segregation of slabs.
