In order to decrease center segregation together with center porosity, electromagnetic stirring has been applied to continuous casting of billets, blooms and slabs. As well known, however, the violent agitation in the pool is powerful to prevent center segregation, but promotes the formation of white band To tackle this problem, the turbulent electromagnetically driven flows in the pool are theoretically analyzed. Especially focusing on the effect of the electromagnetically driven reverse-turn flows on the structure, the solidification experiments were conducted by use of the Sn-10% Pb alloy Theoretical equation of the maximum velocity appearing at every half period for the reverse-turn flow is given as follows where, B = k3 yfr^/\(aw/ti)l/4B}.
