POURING METHOD OF MOLTEN METAL

摘要

PURPOSE:To suppress closing of a nozzle and to stabilize continuous operation by acting the DC magnetic field to the molten metal flow passing through the inside of the nozzle and preventing sticking of an inclusion to the inside surface of the nozzle. CONSTITUTION:The molten metal 2 in a tundish 1 flows through the inside of a nozzle 3 and is poured into a casting mold 4. The molten metal 2 passes through the magnetic field of an electromagnet 5 by which the flow is made laminar and the chance at which the inclusion in the metal 2 sticks to the inside surface of the nozzle 3 is decreased. The closing of the nozzle 3 is thus suppressed and the continuous operation is accomplished stably.
