Abstract
PURPOSE: To float and remove non-metallic inclusions, segregated elements, etc. together with the air bubbles rising in the center of rotation and cast the clean cast ingot by forming the mold to vertical type and feeding gas into the molten metal from the bottom during rotation.
CONSTITUTION: When gas is fed into the molten metal through piping 22 while the mold is being rotated, air bubbles 19 float in the central part of the mold without diffusing. At this time, non-metallic inclusions and segregated element thickened portions 20 of smaller specific gravities are adsorbed by the air bubbles 19 and discharged to the molten metal surface from the central part. The upward current of the molten metal becomes downward current 21 as the air bubbles 19 elute, thereby making natural convection. At the same time, lining 6 causes the solidification of the molten metal around porous bricks 7 to stagnate, thereby maintaining gas supply. Unless the relations of d≤8461N×(square root of h) are established among the inside diameter d of the opening of the head top part refractories 2 of the pouring port and heat metal frame 1, the number of revolutions of mold Nrpm and the recess depth h of the molten metal surface, the molten metal will overflow and fly through the opening during rotation.
