Effect of an AC Magnetic-field on the Dead-zone Range of Inclusions in the Circular Channel of an Induction-heating Tundish

In this paper, the radial electromagnetic force in horizontal circular channel of an induction-heating tundish is derived. A dimensionless trajectory model inclusion developed and numerically solved to acquire moving inclusion. When lower half channel, direction vertical component pinch which acts on opposite buoyancy. Provided their magnitudes are same, there a balanced-position for inclusions channel. Therefore, dead-zone exists near balanced-position, where removal time with AC magnetic-field longer than without it. Then, effect parameters range identified, makes it possible improve efficiency inclusions. The decreases increasing intensity. intensity 56.3, shielding parameter 10–15.9 optimal decrease dead-zone.
