Abstract

Abstract

The helical, linear and rotary magnetic field were employed in the experiment on solidification of the molten metal Tin (Sn) by means of a new type of multifunctional electromagnetic stirrer (EMS). The influences of the stirring types on the metallurgical effects were investigated. The results of industrial test at secondary cooling zone for billets demonstrated that the helical EMS can mitigate the white band for strand, increase the ratio of the equi-axial zone, decrease the defects in the central part, improve macrosegregation and distribation of the inclusions, and help to remove the inclusionst
