Description

By preliminary tests for small ingots of Type 430 steel, the effect of electromagnetic stirring on refining of solidification structure was confirmed.<BR>A pair of linear-motor type stirrers was set in the slab caster and conditions of stirring and temperature of liquid steel in tundish for refining of solidification structure were investigated. By electromagnetic stirring of such a mode that directions of the two stirrers are same and are reversed every ten seconds, and by controlling the superheat of liquid steel in 15 to 25°C, equiaxed structure more than 50% in thickness of slab is secured and the ridging of cold sheet is improved.
