Abstract

PURPOSE: To increase the contact time between molten metal and an inoculant, and improve inoculation effect by applying rabbling force to the inoculant installed in the pass position of the molten metal by using electromagnetic force.
CONSTITUTION: A pocket 1 is provided in a position where the molten metal 1 in a mold passes, and a prescribed inoculant is installed therein. An electromagnetic furnace body 2 is installed on the outside circumference of this pocket 1 by applying side pressure under which the molten metal does not directly contact, and the rabbling force in an upward or rotating direction is applied by about 200W450 gauss electromagnetic force. Thereby, the melting of the inoculant into the molten metal is accelerated and the effect of inoculation is improved.
